+# Renderer C++层第一阶段收口计划
+
+日期: `2026-04-13`
+
+## 1. 文档定位
+
+这份文档是 `Render Graph` 之前的最后一轮 `native render kernel v1` 收口计划。
+
+目标不是继续往当前 `Rendering` 层里塞新功能，而是先把下面几件事彻底做清楚：
+
+- `request -> frame plan -> execution` 三层语义分开。
+- `RenderSceneExtractor -> CullingResults -> RendererList -> DrawSettings` 这条数据组织链正式化。
+- `BuiltinForwardPipeline` 从“大杂烩渲染器”收成“协调器 + 子能力”。
+- `Editor` 注入点、阴影、主场景、后处理之间的边界说清楚。
+- 给下一步 `C++ Render Graph` 留出稳定输入，而不是把当前混乱直接 graph 化。
+
+结论先写在前面：
+
+- `Render Graph` 应该做在 `C++ native` 层。
+- 现在还不应该直接开做 `Render Graph` 或 `Deferred Renderer`。
+- 当前更优先的是把现有渲染层整理干净，再往 SRP/URP 方向演进。
+
+## 2. 当前阶段已经完成的收口
+
+截至 `2026-04-13` 晚间，已经落地的内容：
+
+- `CameraRenderRequest -> CameraFramePlan` 已经分层，`CameraRenderer` 开始正式消费 plan。
+- `CullingResults / RendererList` contract 已经进入 `RenderSceneData`。
+- `Forward / Depth / ObjectId` 已经优先走 `RendererList`，旧 `visibleItems` 只保留过渡 fallback。
+- `RendererListUtils` 已经把可见项遍历规则收口成公共工具。
+- `Gaussian / Volumetric` 已经从 `BuiltinForwardPipeline` 中抽成统一 `SceneRenderFeaturePass`。
+- `FrameExecutionContext / ScenePhase / DrawSettings` 已经引入。
+- `RenderPipeline` 已经支持新的 `FrameExecutionContext` 入口，旧三参数入口保留为兼容适配层。
+- `BuiltinForwardPipeline` 已经开始按 scene phase 组织主场景执行。
+- `CameraRenderer` 主场景阶段已经走新的 execution context，而不是继续只传三参数。
+
+本轮验证结果：
+
+- `XCEditor` 已重新编译通过。
+- `rendering_unit_tests` 已重新编译通过。
+- `editor_tests` 已重新编译通过。
+- `editor_tests --gtest_filter=*ViewportRenderFlow*:*SceneViewportRenderPassBundle* --gtest_brief=1` 通过 `14/14`。
+- `rendering_unit_tests --gtest_filter=*BuiltinForwardPipeline*:*RenderPass*:*CameraSceneRenderer*:*Shadow*:*ObjectId* --gtest_brief=1` 通过 `67/68`。
+- 唯一失败仍然是既有老问题：
+  `BuiltinForwardPipeline_Test.OpenGLRuntimeTranspilesForwardShadowVariantToLegacyClipConventions`
+
+## 3. 为什么现在还不能直接上 Render Graph
+
+现在直接上 `Render Graph`，本质上是在 graph 里继续承接当前的隐式耦合，问题只会换个位置存在。
+
+当前还没完全收口的核心问题不是“没有 graph”，而是下面这些边界还不够正式：
+
+- `CameraRenderer` 和各类 scene pass 之间，谁负责组织阶段，谁负责执行，还没有完全模块化。
+- `Shadow` 相关逻辑仍然分散在 planner、camera execution、pipeline、surface cache 几处。
+- `BuiltinForwardPipeline` 虽然已经开始瘦身，但还没有彻底收成一个明确的 coordinator。
+- `Editor` 的扩展点虽然已可用，但 contract 还偏“约定式”，还不够像以后给 `C# SRP` 暴露的正式接口。
+- 目录结构仍然在暴露旧历史：一些“子系统”目前还是文件堆，不是真正的模块。
+
+如果这些问题不先解决，`Render Graph` 只会变成一个新的承压层，后面再拆更贵。
+
+## 4. Render Graph 和未来 SRP/URP 的边界
+
+未来的推荐结构仍然是这条线：
+
+`RHI -> Native Render Kernel -> Render Graph -> SRP-like Contract -> Universal Renderer -> C# Custom Pipeline`
+
+其中边界应当明确成这样：
+
+- `C++ native` 保留：
+  - `Render Graph`
+  - `CullingResults / RendererList`
+  - draw / dispatch context
+  - GPU resource cache
+  - shadow map / atlas 执行能力
+  - Gaussian 排序与 working set
+  - Volume 资源上传与底层执行
+- `URP-like` 包层保留：
+  - feature 编排
+  - pass 注入顺序
+  - renderer feature 配置
+  - 用户级 pipeline 组合
+  - 未来的 `C#` 自定义渲染管线 API
+
+这意味着：
+
+- 阴影、Gaussian、Volumetric 不是整块搬去包层。
+- 包层更像 Unity 的 `URP renderer` 和 `renderer feature`。
+- native 层更像 Unity 没公开给用户、但真正负责执行和图资源生命周期的内核。
+
+## 5. 第一阶段还差哪些工作才能收口
+
+### 5.1 Shadow 子系统正式化
+
+这是当前最值得先做的一块。
+
+现状问题：
+
+- 阴影规划在 `Planning`。
+- 阴影 surface/cache 在 `Execution/Caches`。
+- 阴影执行又是 standalone pass。
+- 主场景采样阴影的状态切换仍在 `BuiltinForwardPipeline`。
+
+这说明阴影现在“能跑”，但还不是一个正式子系统。
+
+收口目标：
+
+- 明确 `shadow planning / shadow resources / shadow execution / shadow sampling contract` 四层边界。
+- 把方向光阴影相关共享数据收成一组正式类型，而不是散落在多个调用点上。
+- 为以后扩展 `cascades / shadow atlas / additional light shadows / baked shadowmask` 留出位置。
+
+### 5.2 Editor 注入点正式化
+
+现状问题：
+
+- 当前有 `pre scene / post scene / overlay / object id / outline / grid` 多种 editor 路径。
+- 这些能力已经能工作，但还没有统一成“正式 stage 注入 contract”。
+
+收口目标：
+
+- 明确哪些注入点属于 runtime 正式阶段，哪些属于 editor-only extension。
+- 让 `CameraFramePlan` 对这些阶段的描述更加稳定。
+- 给以后 `C# renderer feature` 的注入点设计提供 native 对照物。
+
+### 5.3 BuiltinForwardPipeline 继续瘦身
+
+本轮已经完成第一刀，但还没收完。
+
+还需要继续做的事情：
+
+- 把 forward scene phase 执行和底层 draw/resource 逻辑彻底分开。
+- 把 forward renderer 自己的内部资源、skybox、feature 协调代码进一步收拢。
+- 保证 `BuiltinForwardPipeline` 自己只表达“阶段顺序和协调”，不再继续膨胀。
+
+### 5.4 旧 fallback 的裁边
+
+当前有一些过渡兼容层是故意保留的：
+
+- `RenderPipeline::Render(context, surface, sceneData)` 旧入口
+- `visibleItems` fallback
+- `BuildRenderRequests` 旧习惯入口
+
+这些现在不该硬删，因为会影响现有 tests 和 editor 链路。
+
+但第一阶段收口前，至少要做到：
+
+- 新主链默认只走正式 contract。
+- 旧入口只作为 adapter，不再新增依赖。
+- 每个 fallback 都有明确退出条件。
+
+### 5.5 测试和文档补齐
+
+当前已有回归还不够系统。
+
+还需要补的重点测试：
+
+- `FrameExecutionContext` 是否完整透传 source surface / source color view / state。
+- `BuiltinForwardPipeline` scene phase 顺序是否稳定。
+- feature pass 的 `Prepare -> Execute` 顺序是否稳定。
+- editor 注入点在有后处理和无后处理两种情况下是否仍能保持正确 source/destination surface。
+- shadow planning 和 main scene shadow sampling 之间的契约测试。
+
+## 6. 下一步最优先该做什么
+
+下一步最优先建议做：
+
+`Shadow 子系统收口`
+
+原因很直接：
+
+- 它横跨 `Planning / Execution / Pipeline / Resources / Sampling`。
+- 它是以后 `Deferred / Light Baking / ShadowMask / Additional Light Shadows` 的共同基础。
+- 它也是未来 `Render Graph` 最敏感的一类资源依赖链。
+- 如果阴影先不收，后面 graph 化时 barrier、resource lifetime、pass dependency 都会更乱。
+
+建议顺序：
+
+1. 先把方向光阴影的 plan/data/resource/execute contract 固化。
+2. 再把 editor 注入 contract 固化。
+3. 然后做第一轮目录收拢。
+4. 最后判断这一阶段是否可以正式收口，进入 `Render Graph` 设计。
+
+## 7. 当前 Rendering 目录结构存在的问题
+
+### 7.1 `FrameData` 目录太杂
+
+现在 `FrameData` 里同时混着：
+
+- camera/environment 数据
+- scene snapshot
+- visible item
+- culling results
+- renderer list utils
+
+这说明它不是一个明确模块，而是“跟帧有关的先放这”。
+
+建议方向：
+
+- `FrameData` 保留纯只读帧快照类型。
+- 把 `CullingResults / RendererList / Filtering / Sorting / DrawSettings` 逐步收进更明确的 `Execution` 或 `Culling` 子域。
+- `RendererListUtils` 这种执行辅助逻辑，不适合长期留在 `FrameData`。
+
+### 7.2 `Passes` 目录混合了三类东西
+
+现在 `Passes` 里同时有：
+
+- 主场景 pass
+- fullscreen/post-process pass
+- editor pass
+
+这会让“runtime 正式渲染能力”和“editor 辅助渲染能力”继续混在一起。
+
+建议方向：
+
+- `Passes/Scene`
+- `Passes/Fullscreen`
+- `Passes/Editor`
+- `Passes/Shadow`
+
+不一定要一次性全搬，但后面新增文件不应继续平铺。
+
+### 7.3 `BuiltinForwardPipeline` 还没形成真正子模块
+
+当前 forward 相关代码已经分散在：
+
+- `BuiltinForwardPipeline.h/.cpp`
+- `BuiltinForwardPipelineSkybox.cpp`
+- `Internal/BuiltinForwardPipelineResources.cpp`
+
+这已经具备“应该单独成目录”的条件。
+
+建议方向：
+
+- `Rendering/Pipelines/BuiltinForward/`
+  - `BuiltinForwardPipeline.h`
+  - `BuiltinForwardPipeline.cpp`
+  - `BuiltinForwardPipelineScene.cpp`
+  - `BuiltinForwardPipelineResources.cpp`
+  - `BuiltinForwardPipelineSkybox.cpp`
+
+这样后面 forward / deferred / universal renderer 才能并列演进。
+
+### 7.4 `Shadow` 目录还不算真正的 shadow 子系统
+
+目前虽然已经有 `Rendering/Shadow`，但从全链路看，阴影的责任仍然散在其他目录。
+
+建议方向：
+
+- `Shadow` 目录最终至少容纳：
+  - planning types
+  - shared frame data
+  - runtime resources / caches
+  - shadow executor or shadow renderer
+
+### 7.5 `Internal` 边界不稳定
+
+现在 `src/Rendering/Internal` 更像历史遗留缓冲区。
+
+长期风险：
+
+- 真正属于 forward 的内部实现放在全局 `Internal`
+- 真正属于 volume / splat / shadow 的内部实现也可能继续堆进去
+
+建议方向：
+
+- 全局 `Internal` 只保留跨模块公共 helper。
+- 各子系统自己的内部文件放回各自目录。
+
+## 8. 建议的第一轮目录收拢动作
+
+这一轮只做低风险收拢，不做大搬家。
+
+建议动作：
+
+- 把 `BuiltinForwardPipeline*` 相关实现收成 `Pipelines/BuiltinForward/` 子目录。
+- 给 `Passes` 至少先分出 `Editor` 和 `Fullscreen` 两个子目录。
+- 给 `Shadow` 补一组正式 shared types，再决定是否移动更多实现文件。
+- 暂时不大动 `include` 层 public 路径，先保证编译和引用稳定。
+
+原则：
+
+- 先按职责拆，再按目录搬。
+- 不为了“好看”做纯目录手术。
+- 每次收拢都必须带编译和回归。
+
+## 9. 第一阶段收口完成的判定标准
+
+满足下面这些条件，就可以认为 `Render Graph` 之前这一阶段基本收口：
+
+- `CameraFramePlan` 成为主执行入口，旧 request 入口只保留兼容壳。
+- `FrameExecutionContext / ScenePhase / DrawSettings` 成为主场景执行正式 contract。
+- `CullingResults / RendererList` 成为主要 draw organization contract。
+- `BuiltinForwardPipeline` 被收成 coordinator，而不是继续长成总垃圾堆。
+- `Shadow` 成为清晰子系统，而不是散点逻辑。
+- `Editor` 注入点形成稳定 contract。
+- 目录结构不再继续鼓励“新逻辑直接往老文件里塞”。
+- 相关 tests 和编译链稳定。
+
+到这一步，再开始 `C++ Render Graph`，代价才是可控的。
+
+## 10. 当前建议
+
+当前最佳路线不变：
+
+- 短期：继续按 Unity 的 `SRP + URP` 方向做 native 基座。
+- 中期：先在 `C++` 做出稳定的 `Render Graph + RendererList + Feature Injection` 内核。
+- 中长期：再暴露 `C#` 自定义渲染管线接口，做你自己的 `URP-like` 包层。
+
+眼下最正确的动作不是“赶紧补 deferred”，也不是“先把所有特效搬去包层”，而是：
+
+`先把当前 native rendering layer 整理成一个真正可扩展的内核。`
