refactor: workspace layout — crates/, app at root, legacy C++ removed
Single mechanical restructure commit: - root Cargo.toml = oakapp bin + workspace; one cargo build produces oakapp, oak-cli, oak-worker, liboakengine.dylib - app/rust/src -> src/ (app at repo root, no rust/ nesting) - src/<mod>/rust -> crates/oak<mod>; src/oakcore-rs -> crates/oakcore; src/bindings/oakotio -> crates/oakotio; src/engine/rust -> crates/oakengine (keeps cdylib+staticlib+rlib) - public C headers include/<mod>/ -> crates/oakengine/include/<mod>/ - OFX SDK headers vendored into crates/oakplugin/ofx/ (HostSupport gone) - legacy deleted: old src/ C++ modules, engine/, core/, ffmpeg_bridge/, app/ (Qt), cli/worker C++, root CMakeLists, third_party/KDDockWidgets submodule, otio-install, all build-* output (~40GB) - oakstorage kept but excluded from the workspace (skeleton w/ todos); gpui excluded (own workspace) - verified: cargo build green, cargo test --workspace 1845/0 (with the documented OCIO_RS_* env override for the homebrew OCIO)

//! render 驱动：`src/render/src/plugin/pluginrenderer.cpp`
|
||||
//! `PluginRenderer::render_plugin`（1857 行 C++ 的一部分）的渲染流程
|
||||
//! 语义收编（M11 §4）。
|
||||
//!
|
||||
//! 目标：oakrender 的 PluginJob 退化为一次 C ABI 调用（
|
||||
//! [`crate::ffi::oakplugin_instance_render_job`]），本模块承载全部
|
||||
//! OFX 宿主渲染流程。逐段对照的 C++ 行号已注释。
|
||||
//!
|
||||
//! ## 流程（render_frame，对应 render_plugin）
|
||||
//!
|
||||
//! 1. 实例锁（pluginrenderer.cpp:1436-1444）+ 取消检查；
|
||||
//! 2. use_opengl 决策（pluginrenderer.cpp:1446-1457）：插件描述符
|
||||
//! kOfxImageEffectPropOpenGLRenderSupported ∈ {true, needed} 且
|
||||
//! 渲染器是 OpenGL 且目标纹理有 GL id；
|
||||
//! 3. 输入纹理收集（pluginrenderer.cpp:1518-1552）：effect_input_id
|
||||
//! 匹配 → job.src；否则按 clip 名的纹理表；SimpleSource 回退；
|
||||
//! 4. getClipPreferences（pluginrenderer.cpp:1554-1594）；
|
||||
//! 5. RoI/RoD 设定（pluginrenderer.cpp:1596-1607）：region_of_interest
|
||||
//! = 目标尺寸（规范坐标）；输出 clip 的 RoD 与输出纹理挂接；
|
||||
//! 6. 输入 clip 的 RoD 与格式（pluginrenderer.cpp:1627-1665；Phase 2
|
||||
//! 全链路 F32 → 无转换）；
|
||||
//! 7. getRegionOfInterest（pluginrenderer.cpp:1666-1680）：RoI 为
|
||||
//! 建议值，任何失败按默认整帧继续（C++ 对 BadHandle 即如此；
|
||||
//! Phase 2 其余状态同样继续——RoI 仅影响上游渲染范围，本管线
|
||||
//! 输入由 oakrender 整帧提供）；
|
||||
//! 8. 输出 clip 格式（pluginrenderer.cpp:1686-1697）；
|
||||
//! 9. **isIdentity 短路**（ofxRendering "Identity Effects"）：
|
||||
//! isIdentity 命中 → 直接把所引输入 clip 在透传时间的帧拷入
|
||||
//! 输出（不调 render action）；
|
||||
//! 10. 参数覆盖（pluginrenderer.cpp:132-290 apply_param_overrides）；
|
||||
//! 11. render action：CPU 路径经 [`crate::instance::Instance::render`]
|
||||
//! （输出装配：图像 → 目标纹理帧，行跨度感知）；GL 路径经
|
||||
//! [`crate::instance::Instance::render_gl`]（插件直接画进已附着
|
||||
//! 的输出纹理，无 CPU 回读）。
|
||||
//!
|
||||
//! ## begin/end 序列括号
|
||||
//!
|
||||
//! ofxRendering 文档："All calls to the render action are bracketed by
|
||||
//! a pair of begin/end sequence render actions"。oakrender 对同一实例
|
||||
//! 的一批帧先 [`begin_sequence`] 后 [`end_sequence`]，中间逐帧
|
||||
//! [`render_frame`]。
