# Tessera GUI automation
|
||||
|
||||
[workflows](workflows/README.md) contains repository workflows.
|
||||
|
||||
## CI source checkout
|
||||
|
||||
All workflows use `runs-on: ces-control`; no shared Runner configuration is changed.
|
||||
`actions/checkout@v4` reads source over HTTPS using Gitea's automatically supplied
|
||||
`GITEA_TOKEN`. No additional SSH key or known_hosts secrets are required, and
|
||||
`persist-credentials: false` prevents credentials from being retained for later
|
||||
build steps.
|
||||
|
||||
Consumer workflows read the exact Aster commit from the checked-out project's
|
||||
`vendor/aster` gitlink, then use another standard checkout into that directory and
|
||||
verify the resulting HEAD. They do not follow Aster main automatically. Aster is
|
||||
currently a public repository, so reading it does not require private cross-repo
|
||||
authorization. If that visibility changes, diagnose the job token's read access
|
||||
instead of assuming an SSH key must be distributed.
|
||||
|
||||
The SSH URL in `.gitmodules` is retained for developer Git operations, which
|
||||
continue to use the dedicated codex-bot identity. CI's built-in job token is
|
||||
separate from local developer credentials.
|
||||
|
||||
Workflow definitions do not prove CI passed. CI/deployment state is not queried
|
||||
automatically. Local runtime checks are not performed for Aster, Lyra or Hestia;
|
||||
Tessera permits local native builds/window runs, with automated tests in CI.

# Tessera GUI workflows
|
||||
|
||||
[ci.yml](ci.yml) verifies this project on main pushes and manual dispatch from main. It runs on ces-control, with a 60-minute timeout. HTTPS checkout and job token details are in [the parent README](../README.md).
|
||||
|
||||
There is no production service deployment in this workflow.
|
||||
|
||||
The container includes the Endor examples used by the live guide and tests. It
|
||||
validates the actual Aster-backed source-to-UI path, snapshot lifetime, layout and
|
||||
execution budgets, failed-update preservation and stale-result invalidation, in
|
||||
addition to the existing rendering checks and Clippy. Cargo uses official sources.
|
||||
The primary example now executes top-level let statements and ui.page().render
|
||||
through Aster's Interactive interface. Function-entry compatibility, original
|
||||
source positions, page methods and page budgets are also checked. The workflow
|
||||
checks the macOS packaging script's syntax without running it on Linux.
|
||||
Docker is used only in this remote workflow; local compilation is native.
|
||||
|
||||
The test image installs DejaVu Sans/Mono and Noto CJK for font metrics and Chinese
|
||||
fallback checks. Text regression tests inspect glyph selection, measured advances,
|
||||
fractional scale, multiline bounds, Unicode truncation and antialiased opacity.
|
||||
|
||||
## Incremental verification
|
||||
|
||||
Gitea 1.26 concurrency groups cancel superseded runs on the same ref. Markdown-only
|
||||
pushes to main skip verification; pull requests do not trigger this workflow; executable Endor examples and Rust
|
||||
files (including embedded guide strings) still trigger checks. Manual dispatch
|
||||
runs verification only when main is selected. Existing queued runs created from older workflow
|
||||
revisions retain their old behavior.
|
||||
|
||||
The workflow invokes [verify-ci.sh](../../scripts/verify-ci.sh). Docker builds the
|
||||
Rust 1.91.1/system/font toolchain from Dockerfile.ci over stdin, without sending a
|
||||
source build context. The checkout is mounted read-only at /build. Named volumes
|
||||
persist Cargo registry/git downloads and /cargo-target across container removal,
|
||||
including failed tests and cancelled runs. Main push and manual runs use the main cache scope. Changing Rust/toolchain compatibility requires updating
|
||||
the image and cache prefix in the script. Cargo lockfiles and fingerprints decide
|
||||
which dependencies/artifacts are reusable; caches do not bypass checks.
|
||||
|
||||
A host flock serializes each scope's writable target cache. Signal handling
|
||||
removes only the current run's named container; it never prunes shared Docker
|
||||
resources or deletes cache volumes. The first run populates caches; later runs
|
||||
still execute fmt, all tests and Clippy. Cargo compilation remains single-job to
|
||||
limit memory pressure on the shared host. No CPU-time guarantee is implied.

Mount.bounds() rejects reads during measurement, including old geometry on an existing Mount. The current occurrence's allocated Bounds become available while its arrange method runs. Structural contexts are prepared before layout, geometry is committed after successful layout, and onMount/onUnmount notifications then run before paint/publication. Both layout phases share one read-only VM call and instruction budget; temporary results can be modified, existing business state cannot. Read versions are captured before hooks, so a hook changing a measured dependency schedules another pass before publication. Dependencies are currently tracked per object. Source measurement results are cached by Mount identity, method, child sizes, constraints and actual object reads, including decoding an existing returned MeasureResult. Cache entries contain borrowed identities and versions, adding no GC roots. Mount-reading measurements currently bypass the cache conservatively because object-level tracking cannot distinguish layoutVersion/geometry from stable structure. Global dictionary writes or changes to another field on a read object can also cause conservative misses. Native measurements keep their shape cache, and arrangement still visits each active occurrence. ui.stats() exposes sourceMeasureHits/sourceMeasureMisses; diagnostic statistics are rejected inside read-only rendering because allocation/count observations are not stable layout inputs.

Native dragging starts after 12 logical pixels and shows a blue insertion marker. Same-window drops call the actual Page `moveTab` and `activate`; cross-window drops first call `moveToWindow`. Source overrides participate. An override that declines or redirects the window move prevents the remaining destination reorder. Page identity and Page-owned tasks survive movement, while a cross-window move replaces Mounts and cancels old Mount tasks. Invalid source/target generations, layout versions or unpublished tab orders are rejected before callbacks. Callback failure stops the domain; earlier writes do not roll back. Escape cancels a drag. Overflow drops use visible gaps; drag auto-scroll remains pending. See [tab-placement.endor](examples/tab-placement.endor).

`window.close()` and a secondary native close button call the same managed method.

Window resource objects may remain referenced after closing, but reject resource operations; id/pages remain queryable.

Open Pages appear in the native shell tab bar. Set `page.title` to label a tab; omitted titles use their open-order number. Clicking a tab or its close control calls the actual Page's `activate()` or `close()` method in the existing VM; source overrides participate. Ctrl+Tab / Ctrl+Shift+Tab cycle pages, and Cmd/Ctrl+W closes the active page when the page has keyboard focus. Overflow arrows expose additional pages. Closed Pages follow managed references and GC; a retained Page can be reopened. The tab projection contains opaque session-local IDs and text, with weak reverse lookup in the runtime, and adds no Page roots. Requests carry the published layout version; an old tab event is rejected. Switching creates new presentation Mounts while preserving the business objects. See [tabs.endor](examples/tabs.endor).

The macOS title strip occupies 44 logical pixels and shares its row with the native window controls. The left rail and title strip form one neutral chrome surface. Content is inset by a 56-pixel rail, an 8-pixel top gap, and 8 pixels at the right and bottom. Page constraints use the remaining height; published Mount geometry and event coordinates remain relative to the content area. Window viewport snapshots continue to report the full native inner size. The host translates drawing and native pointer coordinates at this boundary. Console reset preserves the last picture with input disabled until a new live frame is published.
|

The host has one collapsible left sidebar, with page navigation and Console/Sources/Network/Settings. Cmd/Ctrl+B toggles it. Collapsed, the host draws only its expand button alongside the three real macOS window controls; content fills the native inner window with no top strip or surrounding inset. Only this small control area intercepts page input. `ui.viewport()` / `window.viewport()` and the API viewport headers report the available page area, including the width recovered when the sidebar collapses. Page drawings and hit tests share one camera transform. See [page surfaces](docs/page-surfaces.md).

The native window publishes its current logical content size to the existing VM worker on startup, resize and scale changes. The worker coalesces the latest size, updates the managed viewport input, and refreshes the same runtime without adding Console source/history entries. ui.viewport() returns a fresh managed width/height snapshot; reads during rendering depend on the private input object. User changes to a returned snapshot do not resize the window. Unchanged sizes cause no frame; a fresh or unopened Console runtime updates its inputs without replacing a preserved displayed page. Failed resize layouts stop the affected runtime and preserve the displayed frame.

The default Column/Button policy propagates available cross-axis width minus padding and leaves height unconstrained; Row propagates available height and leaves width unconstrained. Page uses both viewport bounds. Native and source desired sizes are clamped to their supplied constraints, while source arrange can still allocate explicit child bounds. The window clips overflow and pointer targeting to its extent; TextBlock wraps to its available width; source layout now settles constraints over repeated measurement/arrangement passes as described below. See [layout-cache.endor](examples/layout-cache.endor). GET code also exposes X-Tessera-Viewport-Width/Height headers without evaluating source.

Row, Column and Overlay can nest with main/cross alignment, per-child alignment, margin, asymmetric border/padding, fixed/auto/fill sizes and min/max constraints. Page owns the root; scrolling is a finite ScrollView around ordinary layout. Scene2D owns world positions and CanvasViewport provides a finite UI box with an explicit Camera2D. Multiple views can share a scene while retaining independent cameras; assigning the same camera explicitly shares navigation. The old `Page.mode` API remains for compatibility.

Scene3D, Group3D, mesh geometry, lights and programmable perspective/orthographic cameras render through finite Viewport3D boxes. OrbitController handles rotation, pan and zoom and can be replaced by an Endor controller. Ray picking and world-space Panel3D UI use the same transforms and depth visibility. A panel can contain ordinary UI, a 2D canvas or another 3D viewport. Rendering currently uses the existing CPU compositor with bounded depth/texture surfaces; this is not a GPU renderer.

Native pointer clicks now resolve source `hitTest(self, mount, point): Bool` overrides in reverse paint order, then dispatch through the existing capture/target/bubble route. The Point is local to that occurrence; `point.inside(bounds)` uses a half-open rectangle and `point.inCircle(cx, cy, radius)` includes the circle boundary. Each candidate is first restricted to its Mount rectangle, so hit shapes can refine that area, but cannot expand it. A rejected target falls through to another interactive occurrence, including a parent. Ordinary Blocks become interactive through a live click subscription or a source onEvent override; disconnecting the final click subscription updates that status.

A waiting coroutine retains its evaluated operand and frames as managed edges; waiting performs no VM execution or active polling. Source side effects and IO initiation before await are not replayed. When the dependency completes, the owning VM worker resumes the waiter through the existing fair quantum scheduler. Cancelling/replacing/closing the waiter releases its frames and operand; it does not automatically cancel an independently owned or shared dependency. Dependency cancellation propagates cancellation to its waiters without running the remainder. An unhandled dependency failure becomes a source await error (with the original provider message), fails the waiter and follows the existing shared-runtime fault rule; provider failure alone still only fails its own Task. Self-await and cyclic Task waits fail explicitly. Read-only layout/paint cannot await. Waiting state is reported as running, while active() remains true; result() is unavailable until completion. These APIs do not introduce try/finally or change the existing exception model.

While a native tab drag is held over an overflow arrow area, the strip waits 350ms then reveals one hidden tab every 120ms, including in a compatible destination window. The preview scroll does not activate Pages or change business state. Drawing, hit testing and insertion gaps share the same transient visible range; release uses its full-order insertion index. Leaving the strip stops the timer; release, Escape, a new press or runtime generation change restores the normal active-tab-centered strip. A resize or changing tab count clamps the range. Native drag/mixed-DPI behavior still requires platform validation; application-exit cleanup is described below.

Application exit now uses a private VM-worker control channel, independent of HTTP queue capacity. Main native close and a managed primary Window.close request asynchronous cleanup; duplicate requests coalesce and mutation requests are rejected with 503 while exiting. An unpublished candidate/input refresh is cancelled without replay. The current VM cancels all Task entries, closes managed windows, detaches occurrences child-before-parent per window, and invokes normal onUnmount hooks once. It does not run layout/paint during shutdown. All windows are closed before hooks run; new windows and tasks are forbidden. A stopped/faulted VM detaches without source hooks; reset/discarded pictures cannot revive an old VM. A hook error aborts remaining source hooks, releases prepared hook roots, drops the VM and reports failure before native exit. Completed shutdown is acknowledged to the GUI, which then ends the event loop. An OS exit bypassing CloseRequested uses a five-second bounded final fallback; non-cooperative native calls remain atomic and force-kill/crash cannot guarantee notifications. Native stderr records the window/mount/task-entry counts and whether source hooks were enabled, or the cleanup error. See examples/exit-lifecycle.endor. Cross-platform exit/drag validation remains broader follow-up work.

## 建议阅读顺序
|
||||
|
||||
1. [main](../src/main.rs)：创建原生循环、共享文档与执行 worker。
|
||||
2. [原生应用](../src/shell/app.rs)：理解窗口生命周期、可用视口、输入边界和最终 present。
|
||||
3. [API worker](../src/runtime/api/worker.rs) 与 [运行时](../src/runtime/endor_host.rs)：理解候选/活跃 VM、输入串行化、分片刷新和发布。
|
||||
4. [桥接层](../src/bridge/ui_bridge.rs)、[Block](../src/model/block.rs) 与 [Mount](../src/model/mount.rs)：区分共享业务对象、每次出现和展示事务。
|
||||
5. [快照](../src/model/snapshot.rs)、[源布局](../src/render/source_layout.rs) 和 [源绘制](../src/render/source_paint.rs)：理解依赖缓存、只读执行及挂起工作。
|
||||
6. [二维视口](../src/render/viewport.rs)、[3D](../src/render/scene3d.rs) 和 [面板映射](../src/render/scene3d/panel.rs)：理解布局/世界/视图的边界。
|
||||
7. [任务](../src/runtime/tasks.rs)、[provider](../src/runtime/io_tasks.rs) 和 [事件传播](../src/runtime/event_dispatch.rs)：理解异步交付资格与生命周期。
|
||||
|
||||
## 阅读时需要保留的边界
|
||||
|
||||
- Block/Data 属于共享业务组成；Mount 属于一个展示位置，不能把一次出现的尺寸写回共享对象来代替排版。
|
||||
- ObjectRef/WeakObjectRef 的含义由真实托管拥有关系决定；派生缓存中的身份索引不能成为隐藏根。
|
||||
- 窗口线程消费完整发布值；VM、源回调和托管堆操作只在执行 worker 内推进。
|
||||
- submission 防止旧请求覆盖新输入；session 防止跨 VM 资源误用；layout_version 防止旧几何上的离散操作误触。
|
||||
- Pending Work 同时拥有续体与上下文；取消必须关闭原 VM 的只读执行并恢复未提交 Mount，不能只丢弃 Rust 值。
|
||||
- 场景世界不是无限尺寸的排版盒子；有限视口参加布局，摄像机负责投影，命中沿相同链逆变换。
|
||||
- 现有 CPU 绘制、缓存范围与输入队列限制仍按当前代码执行；说明性注释不代表性能优化已实现。
|
||||
|
||||
## Rust 逐文件说明
|
||||
|
||||
每行说明该文件本次新增注释解释的职责和目的。生产函数/方法均增加中文入口说明；复杂状态机另外补充阶段和不变量说明。集成测试文件增加整体阅读与检查点说明，测试程序文本和源码范围断言保持原样。

# Endor 脚本：龙与文字实时绕排
|
||||
|
||||
完整程序：[examples/illustrated-manuscript.endor](../examples/illustrated-manuscript.endor)。它通过普通 Page、源 measure/paint、托管事件及 owner-scoped Task 工作。Tessera 没有 Dragon / Flame / Manuscript 专用 Rust 类型、专用启动参数或动画循环；Rust 只补齐可被其他脚本复用的图形与文字能力。
|
||||
|
||||
## 运行
|
||||
|
||||
在仓库根目录启动普通应用：
|
||||
|
||||
```sh
|
||||
cargo run --release --locked
|
||||
```
|
||||
|
||||
另开终端，在同一个仓库根目录提交原始 Endor 文件：
|
||||
|
||||
```sh
|
||||
curl --request PUT --header 'Content-Type: text/plain; charset=utf-8' \
|
||||
--data-binary @examples/illustrated-manuscript.endor \
|
||||
http://127.0.0.1:4737/v1/namespaces/app.main/code
|
||||
```
|
||||
|
||||
这是普通源码提交，没有预编译场景或原生替身。资源路径目前相对于应用工作目录；通过以上根目录启动方式使用 `examples/assets/manuscript/`。从其他目录启动时，修改脚本的 `assets` 路径为绝对路径。图片、字体、正文都在示例目录，不编入宿主。素材与字体许可见 [NOTICE](../examples/assets/manuscript/NOTICE.md)。
|
||||
|
||||
移动鼠标让龙跟随，按住左键喷火，松开停止。离开窗口、取消指针或失焦也会停止喷火。空闲两秒回到卷曲姿势。原生窗口缩放触发普通布局和 paint；窄窗口切换到脚本预备的小字号。关闭 Page 会取消其定时任务，不留下应用级动画循环。
|
||||
|
||||
## 脚本对象分工
|
||||
|
||||
| 对象 | 状态与责任 |
|
||||
| --- | --- |
|
||||
| `Segment` | 一节身体的位置、角度及共享图片引用 |
|
||||
| `FireArt` | 一张火焰图及其原始轴角；这些校准值是示例素材数据 |
|
||||
| `Flame` | 一个粒子的位置、速度、尺寸、年龄及 FireArt 引用 |
|
||||
| `Dragon` | 身体链、火焰集合、目标点、输入状态、时钟样本和随机种子；实现追随、恢复、生成/更新/删除粒子及绘图描述 |
|
||||
| `Manuscript : RectBlock` | 普通视觉子类；组合预处理文字、首字母图片、龙和 Page，覆盖 measure/paint，通过 onMount/onUnmount 管理 Task |
|
||||
| `Page` / `Task` / `Event` / `Mount` | 沿用 Tessera 已有托管体系：Page 是任务 owner，Task 调用脚本 tick，Event 带局部指针位置，Mount 提供当前出现的几何 |
|
||||
|
||||
这些是同一 VM 中的普通对象与引用。身体并不是多个重量远程 actor；图片被多个出现/粒子共享，临时 PaintCommand 只描述本帧绘制。
|
||||
|
||||
## 从输入到一帧
|
||||
|
||||
1. `view.on("pointermove", dragon.pointer)` 显式订阅连续输入。宿主把原生指针转换成 Event，再交给普通传播链；脚本读取 `event.mount.bounds()`，将目标点换算到自己的 700 单位画布。按下/松开只改变脚本 `pressed`。
|
||||
2. `onMount` 用 `ui.after(page,"animation",80,self.tick)` 创建 Page 所有的任务。`tick` 调用脚本 `Dragon.step()`，再安排下一个任务。80 ms 是脚本参数；宿主不知道这是龙的动画。
|
||||
3. `step` 先采样通用单调时钟。头向目标移动，其余 19 节依次跟随上一节，保持间距 30，并把相邻转角差限制在 ±0.25 弧度。空闲时由脚本计算卷曲目标并插值回去。
|
||||
4. 粒子在脚本中更新位置、速度与年龄，倒序删除超过 12 步的粒子。每步最多产生 1 个、总数最多 12 个，最长边仅 12–20 个画布单位。随机变化由脚本自己的确定性种子和数学函数产生。
|
||||
5. 普通属性变更使源 paint 的已观察依赖失效。`paint` 从当前几何生成图像绘制命令，再由脚本选择哪些图片形成避让区，交给通用文字流布局。
|
||||
6. 正常文字使用缓存整词形状；喷火时脚本请求字素粒度，并在 `heat` 中按粒子距离修改临时文字命令的位置、角度、透明度和颜色。没有把热力规则藏进宿主。
|
||||
7. 返回的 DisplayList 经过现有只读 paint 校验、Frame 发布和 CPU 栅格化，在普通窗口中呈现。VM 对象不进入窗口线程。
|
||||
|
||||
paint 内创建/修改的是临时返回对象，不能写已有龙状态或读取文件/时钟。资源加载、时钟采样和状态更新发生在初始化、事件或任务中。
|
||||
|
||||
## 绕排与预处理
|
||||
|
||||
脚本初始化时用 `prepareText` 准备两套正文和提示文字。字体/字号/行高/颜色/设备分辨率属于准备参数；每帧只传新几何与避让区，复用字形形状和透明图像。
|
||||
|
||||
`Dragon.artwork` 返回普通图像命令。脚本循环调用通用 `imageExclusion(command,padding)`，由图片 alpha 轮廓产生保守凸包，并给首字母添加矩形避让。`flowText` 对整个行带求交、合并遮挡区间，再依次填充剩余的左右片段；同一个文字 cursor 跨片段继续，不复制或跳过词。单词装不下所有可用片段时才退回字素边界。
|
||||
|
||||
当前提供面向本示例的从左到右文字流，不声称完整支持所有文字系统的双向段落。字素绘制会改变部分字偶距；这是喷火效果的取舍。正文超出当前页的部分留在准备数据中，当前示例保持单页，未增加滚动文档业务。
|
||||
|
||||
## 火焰角度与尺寸
|
||||
|
||||
火焰 PNG 自身方向各不相同；把它们一律当作朝右图片会错位。脚本在 `FireArt.axis` 中记录每张图片原始轴角，绘制时使用：
|
||||
|
||||
```endor
|
||||
image = p.art.image
|
||||
imageScale = p.size * scale / math.max(image.width, image.height)
|
||||
angle = math.atan2(p.vy, p.vx) - p.art.axis
|
||||
drawing = sprite(image, ox + p.x * scale, oy + p.y * scale, imageScale, angle, 0.5, 0.5)
|
||||
```
|
||||
|
||||
角度以弧度表示，在屏幕坐标中正方向为顺时针；原始素材校准值与 PNG 一起属于应用数据。尺寸按最长边归一化，窄高的 PNG 不会因宽度较小而放大。舌头同样通过局部 anchor 定位，使其偏移随头部一起旋转。
|
||||
|
||||
## 可复用宿主接口
|
||||
|
||||
入口是 `g = ui.graphics`，数学入口是 `g.math`。宿主实现位于 `src/bridge/graphics.rs`、`src/render/image.rs` 和 `src/render/text_flow.rs`。
|
||||
|
||||
| 方法 | 行为 |
|
||||
| --- | --- |
|
||||
| `loadImage(path)` | 读取有界普通 PNG 文件，返回共享不可变资源及 width/height |
|
||||
| `loadFont(path,family)` | 注册开放字体，验证指定 family；相同资源复用，冲突不替换既有字体 |
|
||||
| `readText(path)` / `textSlice(text,start,end)` / `string(value)` | 初始化用有界 UTF-8 资源读取、按字符切片及标量文本转换 |
|
||||
| `prepareText(text,font,size,lineHeight,color,rasterScale)` | 生成与障碍无关的缓存文字资源 |
|
||||
| `sprite(image,x,y,width,height,angle,anchorX,anchorY,opacity)` | 返回普通 PaintCommand；旋转围绕原点，anchor 决定图片局部偏移 |
|
||||
| `imageExclusion(command,padding)` | 图像实际 alpha 轮廓的保守凸包，应用该命令的平移、缩放与旋转 |
|
||||
| `circleExclusion(x,y,r)` / `rectExclusion(x,y,w,h)` | 通用几何避让区 |
|
||||
| `flowText(prepared,x,y,w,h,exclusions,letterMode)` | 生成可检查/修改的普通文字图像命令列表 |
|
||||
| `math.float/sin/cos/sqrt/atan2/abs/min/max/clamp/floor/now` | 通用实数与图形数学；float 是显式二进制浮点入口，now 仅在事件/任务中采样 |
|
||||
| `ObjectList.append/remove/extend/added` | 通用托管集合编辑/批量追加/持久添加；paint 只能编辑本次创建的临时集合 |
|
||||
|
||||
PNG 单张最多 4M 像素，文件最多 4 MiB；准备文字最多 16 KiB、缓存最多 8M 像素；最多 512 个避让区、1024 行和 10000 条绘图命令。资源读取不允许在 paint/layout 中执行。图形边界显式窄化数字，源语言的精确数值表示不会被改写。

原生连续指针输入需显式订阅。生产端在有界队列中只合并相同窗口/session/目标的相邻绝对移动采样，按下/松开/取消及目标变化都是顺序边界。后台 relay 直接把内部 Input envelope 送进同一 VM worker 队列并等待完成，窗口线程不等待；不绕行 HTTP。worker 等既有刷新结束后才重验 Mount/session 并更新连续事件版本，避免动画发布新帧时丢掉移动或松开。外部 HTTP 无法创建内部 envelope，继续严格校验帧版本。
|
||||
|
||||
## Aster 语言扩展
|
||||
|
||||
为使上述逻辑留在源码中，独立 Aster 分支实现了真实四则运算、非字面量负号、六种比较、if/else 与 while，并同步 ASDL、AST 生成产物、名称分析、bytecode 验证与 VM。整数/十进制/有理数保持精确；有 BinaryFloat 操作数才选择浮点算术，混合数值比较避免大整数丢精度。循环沿用同一累计指令限制与协作暂停机制。不是在 Tessera 中解释另一个小语言。
|
||||
|
||||
## 验证与范围
|
||||
|
||||
```sh
|
||||
cargo test --locked
|
||||
cargo clippy --locked --all-targets -- -D warnings
|
||||
cargo fmt --all -- --check
|
||||
TESSERA_MANUSCRIPT_SNAPSHOTS=/absolute/output/path \
|
||||
cargo test --release --locked manuscript_script_snapshots -- --nocapture
|
||||
```
|
||||
|
||||
快照测试加载实际 Endor 文件，经 VM、事件、源 paint 和软件渲染器输出 endor-rest/crossing/fire/narrow 等 PNG。覆盖持续喷火达到上限、角度校准、最长边尺寸、字形呈现、宽窄窗口，以及任务确实调用脚本和关闭 Page 后停止。另一项集成测试验证指针驱动头部移动、取消与粒子回收。不是用 Rust 动画或手工绘图替代源码执行。
|
||||
|
||||
当前采用既有 CPU 后端；无 GPU 实现，也未达到稳定 60 FPS。参考本机 release 样本，16 次持续喷火的 VM 更新与完整 Frame 刷新约 1.4–1.5 秒（不含 OS 呈现），不能把 80 ms 定时参数当作实际帧率。性能结果属于脚本通路而非之前已移除的原生原型。
|
||||
|
||||
|
||||
本次还补上了指针类型的 HTTP 白名单。最初只测 VM 分发遗漏了真实 worker 入口，随后通过真实 HTTP 回归复现并修复 `unsupported event kind`；动画期间的过期事件竞争则通过内部原生 envelope 解决。测试分别覆盖 HTTP 的坐标/类型/严格版本、原生 envelope 换帧后仍投递且旧会话不穿透，以及生产端合并不跨越按下/松开。最终运行窗口已由用户确认“持续正常，松开也正常”。系统自动事件投递/截图权限未开启，因此最终展示图来自实际脚本的 VM→Frame→软件渲染快照，原生交互验证来自用户操作。

# Endorphin 页面空间与窗口边界
|
||||
|
||||
> 下文的 Page.mode 是前一阶段的兼容接口。当前默认页已迁移到普通 Page、Row/Column、滚动容器和独立 Scene2D / CanvasViewport / Camera2D。新代码请使用 [统一场景架构](scene-architecture.md)，不要再把横纵排版或相机作为 Page 的固有模式。
|
||||
|
||||
本次按参考图的“左侧栏展开/收起”两种状态调整原生宿主。窗口保留系统关闭、最小化和缩放按钮；宿主管理入口集中在左侧栏。收起后只保留展开按钮及系统三键，页面从窗口左上角铺满，不再保留顶部标签条、左侧空轨或内容卡片边距。
|
||||
|
||||
页面内容、卡片、文字和操作按钮由 Endor 源码渲染。默认 [开始页](../src/bridge/ui_bridge/start_page.endor) 是真实的画布 Page，其操作创建另外三种 Page；不会把示例的静态截图当作可操作界面。
|
||||
|
||||
## 四种页面模式
|
||||
|
||||
| `page.mode` | 布局 | 浏览方式 |
|
||||
| --- | --- | --- |
|
||||
| `window`（默认） | 根 Page 等于可用区域，子组件按纵向流组织 | 应用自行安排内部布局或 ScrollBlock |
|
||||
| `vertical` | 宽度跟随可用区域，高度至少一屏并随子组件增长 | 纵向滚动，偏移限制到内容范围 |
|
||||
| `horizontal` | 高度跟随可用区域，宽度至少一屏并随子组件增长 | 横向滚动；普通纵向滚轮也可推进横向页面 |
|
||||
| `canvas` | 直接子组件使用各自的 `x`、`y` 世界坐标 | 双向平移、缩放，视角不限制到内容边界 |
|
||||
|
||||
侧栏展开占用 256 个逻辑像素；收起归还全部宽度。`ui.viewport()`、`window.viewport()` 和 GET code 的 viewport headers 均报告实际可用页面区域。窗口变更重排同一个运行时，不重放源码。窗口模式保证根 Page 填满，但不会强迫每个子组件拉伸。
|
||||
|
||||
```endor
|
||||
page = Page()
|
||||
page.mode = "canvas"
|
||||
page.title = "我的画布"
|
||||
card = Button("一个真正的 Endor 组件")
|
||||
card.x = -120
|
||||
card.y = 90
|
||||
page.render(card)
|
||||
page.panX = -200
|
||||
page.panY = 0
|
||||
page.zoom = 1
|
||||
```
|
||||
|
||||
`page.render(root)` 替换内容；`page.append(child)` 继续添加。直接画布子组件的 `x/y` 决定位置，内部 Row/Column 仍使用原来的流式布局；纵向、横向和窗口页面不使用子组件的 `x/y` 排列。共享 Block 可以有多个 Mount，不会为画布复制业务对象。
|
||||
|
||||
## 交互与坐标
|
||||
|
||||
- 滚轮或触控板平移；嵌套 ScrollBlock 优先处理其可滚动方向。
|
||||
- 画布支持空格＋左键拖动、鼠标中键拖动；已有按钮键盘焦点保留 Space 激活。
|
||||
- 画布支持捏合、Cmd/Ctrl＋滚轮缩放，以指针位置为锚点。
|
||||
- Cmd/Ctrl+B 展开/收起侧栏；侧栏提供新建、切换和关闭页面及四个开发工具入口。
|
||||
- Cmd/Ctrl+T 新建，Cmd/Ctrl+W 关闭，Ctrl+Tab / Ctrl+Shift+Tab 切换页面。
|
||||
|
||||
`panX/panY` 是可视区域左上角的世界坐标，`zoom` 为 0.1–4。变换是 `screen = (world - pan) * zoom`；绘制使用正变换，原生点击/滚动使用逆变换。VM 中 Mount 始终使用世界坐标，worker 根据同一视角重新检查可见性。Page 自己保存视角，切换后仍保留；有限页面在内容缩短或窗口变大时限制偏移。
|
||||
|
||||
画布没有内容边界裁剪，但保留现有运行预算：坐标为有限数且绝对值不超过 1,000,000，维度、对象数和绘制命令数仍有上限。“无限”指可以向内容以外导航，不代表无限内存或数值范围。
|
||||
|
||||
原生相机事件 `page-pan/page-zoom` 经过真实 HTTP worker，再由所属 VM 更新 Page；它们使用 `mount=0` 和当前 window/session/layout_version。平移 delta 使用可视区域像素；缩放 delta 为 `[factor,0]`，point 是可视区域内的锚点。普通点击与嵌套滚动的 point 使用世界坐标。过期事件返回 409；不适用于当前模式或参数非法的相机事件在执行前拒绝。
|
||||
|
||||
## 实现位置与验证边界
|
||||
|
||||
- [page.rs](../src/render/page.rs)：模式约束、视角、正逆坐标变换和有限页面偏移限制。
|
||||
- [sidebar.rs](../src/shell/sidebar.rs)：唯一宿主管理栏及折叠后点击遮挡范围。
|
||||
- [page_input.rs](../src/bridge/ui_bridge/page_input.rs)：串行 VM 内的视角变更。
|
||||
- [API 回归](../src/runtime/api/tests.rs)：真实 HTTP 平移、指针锚定缩放、负世界坐标点击、过期/非法事件。
|
||||
- [宿主回归](../src/runtime/endor_host/tests.rs)：四种模式、实时内容增长、共享对象坐标、视角恢复和默认页真实按钮。
|
||||
|
||||
本地格式、153 项测试和 all-target Clippy 均通过；release app 已构建并实际启动。运行中平移与缩放事件返回 200，并读回 Page.panX=80、Page.zoom=2，随后恢复初始视角。最初 HTTP worker 漏接相机事件导致 400，现由完整链路回归覆盖。
|
||||
|
||||
macOS 当前未授予本次工具模拟输入和窗口截图权限。模拟滚轮未生效，无法据此声称真实鼠标/触控板、捏合或窗口外观验收通过。侧栏指针拖放、跨窗口拖放尚未迁移；原有 `moveTab/moveToWindow/detachToWindow` 与版本校验的 API 保留。没有修改 Aster 或引入新的 GUI/语言依赖。

# 场景交互性能研究
|
||||
|
||||
## 结论
|
||||
|
||||
性能问题有可验证的解决路径，但单改 Aster 字典不能让当前世界 UI 达到稳定 60 FPS。本 PR 交付可重复基准和研究记录；去除字符串键比较临时分配的改动仍在独立 Aster 分支，未随本 PR 集成；面板纹理缓存实验因当前示例收益不足而撤回。没有实现 GPU 后端或宣称完成性能目标。
|
||||
|
||||
## 方法
|
||||
|
||||
在 Apple M4 Pro、macOS 15.6 本机使用 release 构建，固定 1024×800 逻辑视口、1× / 2× 像素比例，分别加载 world-ui 和 scene3d 示例。每组执行 33 次真实 scene-orbit 运行时分发，前 3 次作为预热，统计后 30 次的均值、P50、P95。每次先测分发到文档更新，再测变化后的软件绘制，最后测相同显示列表的缓存绘制。没有运行 Console 编译来代替原生事件。
|
||||
|
||||
```sh
|
||||
cargo test --release --locked scene_interaction_performance -- --ignored --nocapture --test-threads=1
|
||||
```
|
||||
|
||||
这是无窗口的运行时与软件渲染基准，包含回调、快照、布局和运行时收尾，但不包含本地 HTTP、OS 事件排队、窗口呈现或输入到显示延迟。阶段耗时不能简单当作实测 FPS。时间是本机样本，不是跨设备保证；基准默认 ignored，普通回归不以绝对耗时断言通过。
|
||||
|
||||
## 对照结果
|
||||
|
||||
世界 UI、2× 像素比例，单位 ms：
|
||||
|
||||
| 条件 | 更新均值 | 更新 P95 | 变化绘制均值 | 变化绘制 P95 |
|
||||
| --- | ---: | ---: | ---: | ---: |
|
||||
| 原始 Aster | 8.456 | 8.843 | 18.704 | 20.742 |
|
||||
| 借用字符串键比较 | 6.842 | 7.226 | 18.598 | 20.665 |
|
||||
| 再加面板纹理缓存实验 | 6.823 | 7.053 | 18.410 | 20.482 |
|
||||
|
||||
去掉字符串键比较的分配后，本组更新均值减少约 19%，绘制基本不变。面板缓存的绘制收益约 1%，不足以证明值得在本次增加缓存与失效复杂度，因此撤回。
|
||||
|
||||
作为对照，普通 scene3d 示例在 2× 下更新约 0.94 ms、变化绘制约 6.15 ms；它的视口尺寸、覆盖像素和 UI 复杂度不同，不能据此把两个示例的全部差值都归给某一层。
|
||||
|
||||
## Aster 发现与保留的修改
|
||||
|
||||
`EndorDictObject` 用插入有序的数组存储，`dict_position` 逐项调用 `key_equal`。原实现每次比较都会把内联文本或托管 String 转成新的 String；查找名称时会重复分配和复制候选键。
|
||||
|
||||
本次只改为借用字符串切片比较。保留线性查找、原 key_equal 分支、对象检查、只读依赖观察、键的插入身份与顺序、写入验证和引用计数流程。新增测试覆盖空文本、普通文本、Unicode、托管 / 内联字符串等价替换、删除和引用释放。
|
||||
|
||||
没有把通用字典直接改成 HashMap，也没有绕过 heap.replace_payload 的事务性边验证。前者还需处理托管键相等 / 哈希与顺序语义；后者涉及 GC、失败原子性和只读保护。它们不属于本次已经证明安全的改动。
|
||||
|
||||
## 尚未解决的主要成本
|
||||
|
||||
1. 世界 UI 的摄像机变化后，当前统计仍为 measured=8、arranged=88；普通 3D 为 measured=0、arranged=14。数据证明相机更新没有彻底绕开排版。
|
||||
2. 3D 变化帧仍在窗口线程逐像素进行 CPU 绘制。当前世界 UI 的绘制本身已超过 60 Hz 的 16.7 ms 预算，其他 CPU 优化不能消除这个事实。
|
||||
3. 原生连续输入仍逐项经本地 HTTP 发送，有界队列不等于按显示帧合并；真实排队和呈现延迟需要另外测量。
|
||||
|
||||
## 后续实施顺序与条件
|
||||
|
||||
1. **相机更新专用路径。** 复用已有 Mount 几何、UI 排版和绘制结果，仅更新视图 / 投影、可见性和命中映射。必须检查源 measure / arrange / paint 的实际读取依赖；源函数若读取相机，应继续正确失效。不能无条件跳过所有布局或绘制。验收：不依赖相机的 UI 在旋转时零测量、零重新排版，依赖相机的源协议回归仍通过。
|
||||
2. **按帧收集连续输入。** 原生操作直接进入进程内通道，连续手势按捕获会话 / 目标与顺序合并；点击、页面切换和运行时替换保持边界。外部 HTTP API 保留严格版本校验。验收包括缩放锚点、非交换手势顺序、嵌套捕获与过期会话，不能只检查最终数值。
|
||||
3. **GPU 合成与独立渲染。** 现有不可变网格、变换、相机、深度和 UV 数据可以成为渲染输入；VM 对象留在运行时线程。GPU 应直接向窗口表面呈现，同时合成 2D / 3D 内容，避免每帧 GPU→CPU 回读后再交给 softbuffer。跨线程队列只保留最新可呈现快照；纹理、缓冲与缓存均需资源预算和正确失效。
|
||||
|
||||
建议验收目标：固定示例 2× 下相机更新 P95 ≤2 ms、GPU 绘制 P95 ≤8 ms，另外记录真实窗口的帧间隔和输入到呈现延迟。目标尚未达到，也没有用无窗口基准宣称原生 60 FPS。
|
||||
|
||||
## 检查说明
|
||||
|
||||
Aster 全工作区测试发现 compiler 的 classes 测试中两项解析失败（第三行 expected EOF），以及 core 的 managed_coroutine_hard_budget_accumulates_and_error_releases_frames 指令预算失败。将对象实现恢复为未优化的基线后，这三项失败均能复现，说明不是本次借用字符串比较引入；不把全工作区标为全绿。对象层测试通过，Aster 全工作区 Clippy / 格式通过；GUI 为 186 项通过、1 项默认忽略的基准，GUI Clippy / 格式通过。该基准已经另行在 release 模式实际执行。
|
||||
|
||||
本次没有修改用户指向的 builtins.rs 第 176 行（该处是函数对象定义）。实际热路径修改位于 Aster 的 store_builtins.rs。
|
||||
|
||||
## PR #6 主线兼容修复
|
||||
|
||||
2026-11-12：合入最新 GUI main，保留 main 的 Aster f3e1670，而非旧性能分支 fd247ac。旧引用缺少 GUI 目前使用的精确读取依赖接口，不能为性能实验回退。上文数值是原有实验记录，不代表当前主线已经采用借用键优化。本 PR 的最终差异仅包括本研究记录和默认 ignored 的基准；Aster 优化需单独更新其分支并审阅后再集成。PR 标题中的 WIP 将移除，交付范围为可运行基准，不承诺上述后续性能目标。
|
||||
|
||||
本次兼容修复检查：GUI `cargo test --locked` 为 186 passed / 1 ignored；Clippy（全部 target，警告视为错误）、格式和差异空白检查通过。最初沙箱内 9 项 HTTP 测试因不能监听本地端口失败；允许回环网络后全套重跑通过。本次未重跑历史 release 性能采样，也未修改 Aster。

# UI、场景、视口与摄像机
|
||||
|
||||
本次完整实现目标的持续记录。完成布局并不等于完成场景或原生交互验收。
|
||||
|
||||
## 边界
|
||||
|
||||
- Page 负责页面身份、生命周期和根内容。Row、Column、Overlay 负责有限盒子内的排版。
|
||||
- Scene2D、Scene3D 管理世界对象。世界不是一个无限宽高的布局盒子。
|
||||
- CanvasViewport、Viewport3D 是有限的 UI 盒子，可以加入 Row、Column、Overlay，也可以放进世界内的有限 UI 面板。
|
||||
- Camera2D、透视和正交摄像机是显式对象。视口保存自己的尺寸、裁剪和投影比例；共享场景不隐式共享摄像机。
|
||||
- 摄像机控制器独立于摄像机数据。移动相机只改变投影、可见性和命中坐标，不应重新排版无关内容。
|
||||
- 视口覆盖 UI 不随世界移动。世界内 UI 面板拥有有限大小，使用普通布局，再由对应的世界变换呈现。
|
||||
- 嵌套视口的输入逐级逆变换，尊重裁剪和捕获；同一手势不能同时驱动内外相机。
|
||||
- 无限导航受数值、可见对象、递归、内存和绘制预算约束；引用环必须在发布部分结果前拒绝。
|
||||
|
||||
## 当前实现状态
|
||||
|
||||
| 阶段 | 状态 | 证据 / 剩余工作 |

||||

||||

| 3D 场景、视口和摄像机 | 完成 | 软件深度缓冲、网格/变换/灯光、透视/正交相机、可替换控制器、射线拾取、世界空间 UI 及 2D/3D 嵌套 |
|
||||
| 可见性与资源防护 | 完成 | 2D 屏幕索引、3D BVH / 视锥剔除、场景缓存、连续原生事件版本更新、字形 LOD 和嵌套资源预算 |
|
||||

|
||||
|
||||
## 有限盒子的接口
|
||||
|
||||
现有 `Row(padding, gap, children...)`、`Column(padding, gap, children...)` 保留，新增 `Overlay(padding, gap, children...)`。Overlay 为构造协议兼容保留 gap 参数，但叠放不使用 gap；子项顺序决定绘制和命中顺序。
|
||||
|
||||
- `mainAlign`: `start`、`center`、`end`、`space-between`。Overlay 对应横向对齐，不使用 space-between 分散规则。
|
||||
- `crossAlign`: `start`、`center`、`end`、`stretch`。Row 对应纵向；Column 对应横向。Overlay 对应纵向。
|
||||
- `alignSelf`: `auto` 继承所在父容器的 crossAlign，或以上交叉轴选项。属性在对象上，每个 Mount 根据自己的父容器解释。
|
||||
- `marginTop/Right/Bottom/Left`: 外边距参与父容器的测量、主轴分配和对齐。不折叠外边距，不支持负外边距。
|
||||
- `paddingTop/Right/Bottom/Left`: 数值覆盖对应边；`auto` 回退到构造参数或容器的 padding 属性。非容器回退为 0。
|
||||
- `borderTop/Right/Bottom/Left` 和 `borderColor`: 边框占据 border box 内侧，压缩内容空间。原生绘制产生实心直角边框；自定义 paint 可调用基类绘制，也可自行提供完整外观。
|
||||
- `boxWidth/boxHeight`: `auto`、非负数值或 `fill`。保留 RectBlock / ScrollBlock 原有 width/height 和源子类字段语义，通用盒尺寸使用独立名称。数值表示 border box，不包含外边距。
|
||||
- `minWidth/minHeight/maxWidth/maxHeight`: 盒尺寸边界，最低值不得超过最高值。父分配小于最低值时，外部有限约束仍然生效。
|
||||
- 主轴 `fill` 使用零基准分享剩余空间；未显式设置 flex 时权重为 1。最大值饱和后，剩余空间继续分给其他项目。交叉轴 fill 使用父容器提供的有限内容尺寸。没有有限父分配的 fill 报错。
|
||||
- `stretch` 仅拉伸交叉轴 auto 尺寸，遵守盒尺寸边界；数值固定尺寸保留。显式源 arrange 返回的布局始终优先。
|
||||
- `overflow`: `visible` 或 `clip`；后者同时裁剪后代绘制和指针命中。需要滚动时使用 ScrollBlock，滚动轴与内层 Row/Column 排版独立。
|
||||
|
||||
尺寸、边距和边框必须有限、非负，受现有 1000000 上限限制。根约束、每个 Mount 的偏好尺寸、分配、收敛判定及源协议缓存均保持独立。示例见 [box-layout.endor](../examples/box-layout.endor)。
|
||||
|
||||
布局阶段验证：本地 `cargo test --locked` 的 162 项回归全部通过，`cargo clippy --all-targets --locked -- -D warnings`、格式与差异空白检查通过。新增用例执行实际 Endor 脚本，覆盖共享对象在不同父容器中的对齐、实时边距变更、flex 分配、叠放、尺寸边界、文本换行、有限 fill、无界 fill 拒绝、源 arrange 优先、裁剪命中和可运行示例。本阶段尚未重新打包或进行原生指针验收。
|
||||
|
||||
## 2D 场景与视口
|
||||
|
||||
`Scene2D(children...)` 持有世界内容。直接子项的 x/y 是世界位置；Row/Column/Overlay 仍然只解释自己的有限内容布局。给世界内卡片设置 boxWidth，即可在其内部换行和嵌套排版。
|
||||
|
||||
`CanvasViewport(width, height, scene)` 是可参加普通排版的有限盒子，世界范围不参与它的本征尺寸。视口可使用通用盒模型尺寸、边框、内边距和 flex。每个新建视口拥有自己的 `Camera2D()`；显式赋值 `second.camera = first.camera` 才会共享视角。摄像机 x/y 是可视内容左上角的世界位置，zoom 范围 0.01–100；也可以 `Camera2D(x, y, zoom)` 创建。嵌套投影还受合成变换预算限制。
|
||||
|
||||
视口的有限内容框裁剪世界绘制和输入，Overlay 中的兄弟 UI 保持固定。场景内可以放另一个 CanvasViewport：布局坐标不变，投影逐层合成，指针逆变换至目标组件坐标。相机改变时复用不变的测量结果。`view.mounts().at(index).fitView()` 使用指定 Mount 的有限尺寸及场景直接子项的有限边界适配摄像机，不把无限世界当作排版边界。
|
||||
|
||||
滚轮优先交给命中的可滚动 ScrollView；其余平移交给最内层画布。空格加左键或中键拖动锁定开始时的视口，不因指针跨到另一个视口而切换相机；捏合及 Cmd/Ctrl+滚轮围绕指针缩放。`viewport-pan` / `viewport-zoom` 使用真实 Mount 身份及帧版本，通过 HTTP worker 串行修改所属 VM 的摄像机。非法缩放锚点在进入 VM 前拒绝，过期帧返回 409。
|
||||
|
||||
`ScrollView` 是现有 ScrollBlock 的名义子类型别名，滚动轴和其内容 Row/Column 排版独立。默认开始页已使用普通 Page + 独立场景/视口，纵横示例使用 ScrollView 对应的滚动容器组合；不再设置 Page.mode。原有 Page.mode/panX/panY/zoom 暂保留兼容旧脚本，不用于新架构示例。
|
||||
|
||||
示例见 [scene-viewports.endor](../examples/scene-viewports.endor)。回归包含两个视口共享同一业务对象、显式共享相机、嵌套变换、真实点击回调、相机修改时测量数为 0、真实 HTTP 链路及软件渲染像素中的缩放/裁剪。它们不能替代原生鼠标和触控板验收。
|
||||
|
||||
2D 阶段最终验证：169 项本地回归全部通过，all-target Clippy 拒绝 warnings 通过，编辑器未报告错误。默认页的真实按钮事件也已迁移验证。未将原生窗口验收记为完成。
|
||||
|
||||
## 3D 基础接口与当前边界
|
||||
|
||||
- `Scene3D(nodes...)` 管理世界对象；`Group3D(nodes...)` 组合变换。`children` 是 ObjectList，可显式替换；共享节点可以出现多次，路径循环会拒绝。
|
||||
- `Box3D(width,height,depth,color)` 创建网格；`Geometry3D(ObjectList(Vec3(...),...), ObjectList(Triangle3D(a,b,c),...))` 创建不可变顶点/索引缓冲，再用 `Mesh3D(geometry,color)` 实例化。可替换 mesh.geometry；修改原输入 Vec3 不会改写已建立的不可变几何。
|
||||
- 网格/组有 x/y/z、rotationX/Y/Z（角度）、scaleX/Y/Z；局部缩放、X/Y/Z 旋转、平移依序应用，再继承父组变换。`translate(dx,dy,dz)`、`rotate(dx,dy,dz)` 可在 Endor 中直接调用。
|
||||
- `DirectionalLight(dx,dy,dz,color,intensity)` 使用传播方向，Scene3D.ambient 为基础照明。当前材质是完全不透明的平面着色。
|
||||
- `Viewport3D(width,height,scene)` 是普通有限 UI 盒子，可以放入 Row、Column、Overlay 或 Scene2D 中。背景与 3D 内容在独立表面上渲染，再交给现有原生软件合成器；采用实际深度缓冲、六面视锥裁剪，没有用静态图替代三维场景。
|
||||
- 每个新 Viewport3D 有独立 PerspectiveCamera；可用 `view.camera = OrthographicCamera()` 替换，或显式共享同一个 camera。摄像机字段为 x/y/z、targetX/Y/Z、upX/Y/Z、near/far、透视 fov（角度）、正交 height。宽高比由每次视口投影提供，不写回共享摄像机。`camera.translate(...)` 同时平移位置与观察目标。
|
||||
- `OrbitController()` 独立于摄像机数据，默认绑定到新视口。左键拖动旋转，中键/空格拖动平移，滚轮/捏合缩放。view.controller 可替换为提供 `update(camera, gesture)` 的 Endor 对象，或设为字符串 `none` 禁用。CameraGesture 提供 kind、dx/dy、factor、width/height、pointX/pointY。透视缩放改变观察距离，正交缩放改变 height。
|
||||
- `view.mounts().at(index).pick3D(x,y)` 接受投影前页面空间中的指针坐标，返回 RayHit3D 或空值；结果包含实际托管 mesh、世界 point/normal、distance、triangle 和 barycentric。原生指针点击对应视口时，标准 click Event.hit 提供相同结果；点击空白时为空。拾取与绘制共享摄像机和变换，遵守 near/far。

固定 Aster 版本不支持数值算术表达式，不能用 `x = x + dx` 编译控制器。因此示例使用可运行的原生 translate/rotate 操作；自定义控制器可以调用这些方法或直接设置摄像机字段。未修改 Aster 源码或 gitlink。
|
||||
|
||||
3D 表面最长边按需降采样至 2048，单表面不超过 4194304 像素；缓存最多 8 个不可变表面、总计 8388608 像素。三角形、顶点、场景节点、灯光、光栅工作和摄像机范围均有检查；超过光栅预算返回错误，不发布截断的半幅结果。降采样保留原始视口宽高比，使绘制与拾取使用相同投影。
|
||||
|
||||
示例见 [scene3d.endor](../examples/scene3d.endor)。测试覆盖真正的 Endor 构造/修改、最终渲染像素、深度顺序、透视/正交独立视图、近面裁剪、射线回调、可替换控制器的真实 HTTP 路由以及循环/非法几何拒绝。原生硬件交互尚未验收。
|
||||
|
||||
3D 基础阶段检查：176 项本地回归全部通过，all-target Clippy 拒绝 warnings 通过。后续世界空间 UI 与嵌套资源/可见性工作尚未完成，因此整体目标及 PR 仍处于进行中。
|
||||
|
||||
## 世界空间 UI 与组合
|
||||
|
||||
`Panel3D(worldWidth, worldHeight, content)` 把普通 Endor Block 放进 3D 场景。面板有独立的 uiWidth/uiHeight（默认 512×320，整数 1–2048）和不透明 background；本次 UI 表面不实现透明材质。世界尺寸控制平面几何，UI 尺寸提供有限排版约束，两者互不代替。面板与组/网格一样支持位置、旋转、缩放及 translate/rotate。
|
||||
|
||||
内容仍是同一个托管对象树，正常执行 measure/arrange/paint/hitTest；每次出现有自己的 Mount、有限尺寸、滚动状态和纹理。一个组件可以放进多个不同尺寸的面板，不复制其业务状态。3D 摄像机移动不改变 UI 的排版尺寸。UI 绘制指令按面板收集，透视裁剪时保留 UV，并按深度进行透视校正插值；普通网格会正确遮挡面板。
|
||||
|
||||
指针先沿视口摄像机发射射线，再沿可见面板的逆世界变换映射到 UI 像素，然后继续通过内部 CanvasViewport 的逆变换。被其他网格挡住的 UI 无法收到指针命中。拖动捕获使用平面的连续逆投影，因此指针移出面板后不会把同一手势交给另一个摄像机。Mount.toView(x,y) 将组件本地坐标转到页面视图坐标；toLocal(x,y) 执行反向转换，无法命中可见面板时返回空值。pick3D 另提供实际 node/mesh 和实例编号。
|
||||
|
||||
面板 UI 可以继续嵌入 CanvasViewport 或 Viewport3D，后者也可以再包含 Panel3D；普通 Overlay 的兄弟 UI 仍固定在其 UI 空间。引用环在派生布局前拒绝；世界 UI 最多嵌套 8 层，光栅/纹理像素采用统一总预算。滚动视口与普通画布的世界内容不会撑大外层有限视口或外层滚动范围。
|
||||
|
||||
示例见 [world-ui.endor](../examples/world-ui.endor)。世界 UI 阶段的 181 项完整本地回归和 all-target Clippy 均通过；新增回归覆盖真正的像素、托管回调、材质遮挡、多面板独立尺寸、再次嵌入 3D、真实 HTTP 射线/UV 摄像机输入、循环和递归预算。
|
||||
|
||||
## 可见性、连续输入与资源
|
||||
|
||||
3D 场景快照构建世界 AABB 的 BVH，摄像机变化复用相同的不可变场景和索引。视锥查询剔除不可见网格，射线查询按近到远缩小候选；序列化不携带缓存，反序列化后可重建。几何或变换变化会生成新场景和新索引。
|
||||
|
||||
普通 2D 交互和相机目标使用 128px 屏幕网格。每个对象最多进入 256 格，索引总计最多 65536 项；巨大矩形和项目化的 3D 面板 UI 进入精确命中的后备集合。后备集合仍遵循原有裁剪、投影和反向绘制顺序，不因近面投影或索引预算遗漏对象。源 hitTest 仍逐一执行其真实协议，未更改源覆盖行为。
|
||||
|
||||
原生输入使用有界 64 项队列。同一个运行时的连续 viewport / scene / scroll 事件在出队时更新到当前帧版本，保留原窗口、会话和捕获 Mount；目标消失、控制器禁用、运行时更换或失败时丢弃。所有窗口共用同一事件客户端和权威文档。离散点击及外部 HTTP 请求仍严格拒绝过时版本，不自动重放业务动作。队列满时仍可拒绝新输入，不保证任意输入速率下无损。
|
||||
|
||||
文字先裁剪再遍历可见字形像素；字体超过 512 设备像素时使用有界字形位图采样，避免高倍率缩放产生巨大单字形分配。字形缓存逐字检查 4096 项 / 32 MiB 阈值，整形缓存继续限制字符串数量与源字节数。极端放大时清晰度受字形 LOD 限制。面板派生槽位限制为非负 i64，避免哈希高位造成偶发排版错误；重复标识拒绝发布。
|
||||
|
||||
## 原生验证记录
|
||||
|
||||
2026-11-11：本地完整回归、格式、all-target Clippy 和 release 应用打包；实际启动 Tessera.app，通过本机 API 加载 world-ui 示例，并取得原生窗口截图，确认立方体、倾斜面板和内部 Canvas 的显示。系统 `CGPreflightScreenCaptureAccess` 为 true，`CGPreflightPostEventAccess` 为 false；集成的原生自动操作工具还因 OpenSSL 配置读取权限启动失败。因此 API / VM 事件与像素测试不宣称为硬件鼠标或触控板验收。最终检查数量及交付提交在 PR 中记录。
|
||||
|
||||
最终完整回归为 186 项通过；运行中的原生实例验证世界 UI 按钮将计数从 0 改为 1、scene-orbit 改变摄像机、scene-zoom 改变观察距离、重复旧帧请求返回 HTTP 409，空闲连续采样的版本保持一致。保留应用窗口供用户直接操作。

# Illustrated Manuscript
|
||||
|
||||
An interactive illuminated manuscript page featuring an animated dragon that follows your cursor, breathes fire on click, and causes text to flow around it in real-time.
|
||||
|
||||
**[→ Live Demo](https://illustrated-manuscript.vercel.app/)**
|
||||
|
||||
## Overview
|
||||
|
||||
This project renders a medieval manuscript page on Canvas, featuring a hand-painted dragon made of sprite segments. The dragon tracks the mouse cursor with chain-physics (20 body segments with angle constraints), and clicking makes it breathe fire. Text reflows around the dragon body and fire particles each frame using [Pretext](https://github.com/chenglou/pretext)'s `layoutNextLine` API — no DOM measurements, no CSS reflow.
|
||||
|
||||
### Features
|
||||
|
||||
- **Real-time text exclusion** — text wraps around arbitrary moving shapes (dragon body + fire particles), re-laid out every frame via Pretext
|
||||
- **Chain-physics dragon** — 20-segment inverse-kinematics body, hand-painted sprites, wing flapping, idle rest pose
|
||||
- **Fire-breathing** — click to spawn particle bursts from the dragon's mouth; particles push and distort nearby text characters
|
||||
- **Illuminated drop cap** — hand-drawn initial letter in manuscript tradition
|
||||
- **Medieval aesthetic** — IM Fell English font, parchment tones, hand-painted sprites throughout
|
||||
|
||||
## Tech Stack
|
||||
|
||||
- **[Pretext](https://github.com/chenglou/pretext)** — Pure JS/TS text measurement & layout engine by [Cheng Lou](https://x.com/_chenglou). Enables laying out text without DOM reflow, line by line with variable widths
|
||||
- **WebGL2 + 2D Canvas** — offscreen 2D Canvas compositing, uploaded to WebGL2 texture for display
|
||||
- **Vite** — build tool
|
||||
|
||||
## Project Structure
|
||||
|
||||
```
|
||||
src/
|
||||
config.js — constants, responsive layout calculations
|
||||
dragon.js — dragon physics, sprite rendering, fire particle system
|
||||
story.js — manuscript story text
|
||||
main.js — entry point: WebGL pipeline, input, text layout, render loop
|
||||
public/
|
||||
dragon-sprites/ — 23 hand-painted dragon body part PNGs
|
||||
fire-sprites/ — 10 fire particle PNGs
|
||||
img/dropcap.png — illuminated drop cap
|
||||
(IM Fell English loaded via Google Fonts)
|
||||
```
|
||||
|
||||
## Getting Started
|
||||
|
||||
```bash
|
||||
npm install
|
||||
npm run dev
|
||||
```
|
||||
|
||||
Open in browser. Desktop recommended — mobile support is limited.
|
||||
|
||||
## How It Works
|
||||
|
||||
1. **Text preparation**: story text is segmented and measured once via `prepareWithSegments()`
|
||||
2. **Each frame**: dragon segments and fire particles generate exclusion rectangles
|
||||
3. **Text layout**: for each line, available width ranges are computed by subtracting exclusion zones, then `layoutNextLine()` fills each range
|
||||
4. **Fire text effect**: characters near fire particles are displaced, rotated, and color-shifted based on proximity
|
||||
5. **Rendering**: everything composites on an offscreen 2D Canvas, then uploads to a WebGL2 fullscreen quad

It was the third candle the abbess had confiscated, and Sable had nodded gravely each time and stolen another from the chapel stores. She kept reading by its unsteady light, hunched beneath her wool blanket in the scriptorium where the novices slept on straw pallets between the copying desks.
|
||||
|
||||
It was the bestiary that held her. Not the psalter, not the gospels, not the lives of saints with their wooden sufferings. The bestiary. Some brother at Lindisfarne had painted it two centuries ago, and his creatures had a quality she could not name, a weight to them, as if they had been observed from life rather than copied from pattern books. His lions looked hungry. His basilisks looked bored.
|
||||
|
||||
And his dragon, coiled in the lower margin of the forty-seventh leaf, looked like it was breathing.
|
||||
|
||||
She had watched it for six nights before she was certain. The movement was slight, a swelling of the ribs, a settling, barely more than the flicker the candlelight threw across the page. On the seventh night she held her breath and placed a finger beside its painted flank, and the parchment was warm.
|
||||
|
||||
\u201CYou could simply ask,\u201D the dragon said.
|
||||
|
||||
Sable jerked her hand back. The dragon opened one eye, yellow as egg tempera, and regarded her with an expression she recognized from the abbey cats: mild contempt for a creature too slow to be interesting but too close to ignore.
|
||||
|
||||
\u201CI am called Voss,\u201D it said. \u201CThough the brother who painted me called me several other things, mostly under his breath, mostly because I would not hold still.\u201D
|
||||
|
||||
\u201CYou are paint,\u201D Sable said. It came out less firmly than she intended.
|
||||
|
||||
\u201CI am gall ink and oak soot and gum arabic,\u201D Voss replied. \u201CAlso rabbit skin glue, which I find personally offensive. But I am not paint. Paint does not get stiff from two centuries of holding the same pose.\u201D He uncurled one leg and stretched it across the margin rule, his claws dimpling the parchment. \u201CYou, on the other hand, are trespassing. This page is not assigned reading for novices.\u201D
|
||||
|
||||
\u201CI am not a novice. I clean the scriptorium.\u201D
|
||||
|
||||
\u201CEven worse. A servant reading. The brothers would be scandalized.\u201D
|
||||
|
||||
\u201CThe brothers are asleep.\u201D
|
||||
|
||||
\u201CThe brothers,\u201D Voss said, \u201Care always asleep. That is the principal advantage of monasteries.\u201D He yawned, and his breath smelled of lamp-black and something older, something mineral, like a cave after rain. A thin red tongue uncurled and tasted the air above the page.
|
||||
|
||||
Sable leaned closer. In the candlelight she could see the crosshatching of his scales, each one laid down with a single stroke of the brush. The brother who painted him had not scrimped. Most bestiary dragons were outlines stuffed with vermillion, flat and heraldic. This one had shadow under its jaw. This one had a nick in its left ear.
|
||||
|
||||
\u201CWhat do you eat?\u201D she asked.
|
||||
|
||||
\u201CSilverfish, mostly. They get into the binding paste. Occasionally a bookworm, if I am feeling athletic.\u201D He cocked his head. \u201CWhy are you not frightened?\u201D
|
||||
|
||||
\u201CShould I be?\u201D
|
||||
|
||||
\u201CConvention demands it. A maiden, a dragon. There are expectations.\u201D
|
||||
|
||||
\u201CI scrub floors and empty chamber pots. I am not anyone\u2019s idea of a maiden.\u201D
|

Voss made a sound that might have been a laugh. It was dry and papery, like a sheet of vellum being folded. \u201CGood,\u201D he said. \u201CMaidens are tedious. They always scream at exactly the wrong moment. You, at least, have the sense to ask questions first.\u201D
|
||||
|
||||
He settled back into the margin, tucking his tail around the descender of a large Q. \u201CCome back tomorrow night,\u201D he said. \u201CBring a candle that does not gutter so badly. And if you can manage it, a bit of cheese. I have not tasted cheese in two hundred years, but I believe I would still recognize it.\u201D
|
||||
|
||||
\u201CCan you eat cheese? You are made of ink.\u201D
|
||||
|
||||
\u201CI am made of ink that remembers being alive,\u201D Voss said. \u201CThere is a considerable difference.\u201D He closed his eyes. The warmth under Sable\u2019s fingertips faded, and the dragon on the page was still again, just pigment and binder on stretched calfskin, exactly as lifeless as it should have been.
|
||||
|
||||
Sable sat in the dark for a long time after the candle burned out. Then she went to the larder and stole a piece of cheese.\u2026
