+## 第一阶段资源分层 + +### 1. 源资源 + +这是项目中由用户导入的原始文件： + +- `.glb` +- `.gltf` +- `.fbx` +- 后续 `.obj` + +这些文件是输入，不是 MetaCore 运行时直接消费的最终资源。 + +### 2. 导入结果文档 + +导入器解析源文件后，生成一份导入结果文档，用于表达： + +- 导入得到几个网格资源 +- 导入得到几个材质资源 +- 每个网格默认使用哪个材质槽 +- 原始节点层级如何映射 +- 原始命名如何保留 + +这份文档属于导入中间层，主要为导入器、重导入和调试服务。 + +### 3. MetaCore 正式资源 + +第一阶段至少应该落两类正式资源： + +- `Mesh Asset` +- `Material Asset` + +后续再扩： + +- `Texture Asset` +- `Model Asset` +- `Material Instance Asset` + +## 第一阶段推荐资源模型 + +### Mesh Asset + +`Mesh Asset` 第一阶段最少应包含： + +- 资源 GUID +- Mesh 名称 +- 顶点数据 +- 索引数据 +- 法线 +- UV0 +- 切线 +- 包围盒 +- SubMesh 列表 +- 每个 SubMesh 对应的默认材质槽索引 + +如果一个模型含多个材质槽，应该通过 `SubMesh -> MaterialSlotIndex` 关系表达，而不是把整个模型强行压成一个材质。 + +### Material Asset + +`Material Asset` 第一阶段最少应包含： + +- 资源 GUID +- 材质名称 +- 材质类型 +- BaseColor +- BaseColorTexture +- NormalTexture +- Metallic +- Roughness +- MetallicRoughnessTexture +- EmissiveColor +- EmissiveTexture +- AoTexture +- AlphaMode +- AlphaCutoff +- DoubleSided + +第一阶段不要求复杂 shader graph，但必须保证这个资源结构已经是 MetaCore 自己的，不是 `simplepbr` 参数字典。 + +### Texture Asset + +如果当前阶段不想单独做完整纹理资源编辑器，也至少要有稳定纹理资源记录，用于： + +- BaseColorTexture +- NormalTexture +- MetallicRoughnessTexture +- EmissiveTexture +- AoTexture + +第一阶段可以先把纹理当成辅助资源，由材质资源引用。 + +## 模型导入后的材质映射规则 + +这是第一阶段最重要的设计点之一。 + +### 规则 1：导入器保留源模型的材质槽 + +例如一个源模型含 3 个材质槽，导入后应保留： + +- `SubMesh 0 -> Material Slot 0` +- `SubMesh 1 -> Material Slot 1` +- `SubMesh 2 -> Material Slot 2` + +不能在第一阶段就把它们合并掉。 + +### 规则 2：每个源材质生成一个 MetaCore Material Asset + +也就是说，导入器不只是读材质参数，而是正式创建： + +- `Valve_Body.mcmat` +- `Valve_Handle.mcmat` + +类似这样的材质资源。 + +这样后面 Inspector、资源浏览、复用和重导入才有稳定对象可操作。 + +### 规则 3：导入器负责参数归一化 + +第一阶段推荐优先按 `glTF` 语义归一化： + +- BaseColor +- BaseColorTexture +- Metallic +- Roughness +- MetallicRoughnessTexture +- NormalTexture +- Emissive +- DoubleSided +- AlphaMode + +对于 `FBX` 等不完全一致的格式，第一阶段允许做保守映射，但输出必须仍然变成同一套 MetaCore 材质结构。 + +### 规则 4：重导入默认保留资源身份 + +重导入时应尽量保持： + +- 材质资源 GUID 不变 +- 网格资源 GUID 不变 + +否则场景对象和 prefab 的引用会被打断。 + +## 第一阶段推荐的组件模型 + +当前 `MeshRenderer` 只保存： + +- `BuiltinMesh` +- `BaseColor` +- `Visible` + +这不足以支撑真实模型和材质工作流。 + +第一阶段应逐步演进为： + +- `MeshAssetGuid` +- `MaterialAssetGuids` +- `Visible` +- 必要时保留调试型覆盖参数 + +### 推荐结构 + +第一阶段建议 `MeshRenderer` 具备： + +- 一个 `MeshAssetGuid` +- 一个 `std::vector` 用于材质槽引用 +- 一个 `Visible` + +如果 `SubMesh` 数量和 `MaterialAssetGuids` 数量不一致，应在 Editor 和 Cook 阶段报错或警告。 + +### 不建议的做法 + +第一阶段不要继续把材质核心参数直接塞在 `MeshRenderer` 组件里。 + +`BaseColor` 作为调试或临时覆盖参数还能容忍，但长期必须迁回正式材质资源。 + +## Inspector 工作流建议 + +第一阶段材质编辑工作流应分成两层： + +### 1. 对象级 Inspector + +用于编辑： + +- 当前对象引用哪个 Mesh +- 当前对象每个材质槽引用哪个 Material +- 是否可见 + +这一层主要做“资源指派”。 + +### 2. 材质资源 Inspector + +用于编辑： + +- BaseColor +- 贴图槽 +- Metallic / Roughness +- Emissive +- AlphaMode +- DoubleSided + +这一层主要做“资源参数编辑”。 + +不要把“对象引用”和“材质内容”全部混在同一个对象 Inspector 里。 + +## 与 simplepbr 的衔接方式 + +第一阶段 `simplepbr` 应只出现在渲染映射层。 + +也就是： + +- `MetaCoreMaterialAsset` + -> `MetaCoreRenderMaterialParams` + -> Panda3D / `simplepbr` + +### 第一阶段最小映射 + +应至少支持： + +- BaseColor +- BaseColorTexture +- NormalTexture +- Metallic +- Roughness +- EmissiveColor +- EmissiveTexture +- DoubleSided + +### 明确不要做 + +第一阶段不要把 `simplepbr` 的内部参数名、调用方式、配置细节直接暴露到： + +- 材质资源格式 +- Editor Inspector +- 场景组件结构 + +否则后面替换渲染后端时，整条链都要重写。 + +## 首批格式建议 + +### P0：glTF / .glb + +这是第一阶段最应该优先打通的格式。 + +原因： + +- 现代 +- 对 PBR 语义支持较清晰 +- 与材质参数映射天然更顺 +- 适合作为数字孪生模型导入起点 + +### P1：FBX + +可以作为第二优先级。 + +原因： + +- 现实项目里经常遇到 +- 但材质与层级语义更杂 +- 更容易出现导入归一化问题 + +### P2：OBJ + +只建议作为补充格式，不建议第一阶段主打。 + +原因： + +- 表达能力弱 +- 对现代 PBR 工作流支撑差 + +## 保存与打包建议 + +第一阶段推荐： + +- 项目内保留源文件 +- 导入后生成材质/网格正式资源 +- Scene 保存时只引用资源 GUID +- 打包时由 cook 收集依赖资源 + +不要让 Scene 直接内嵌整份材质内容。 + +这对后面： + +- 资源复用 +- 场景共享 +- 材质统一替换 +- 打包依赖分析 + +都更健康。 + +## 错误与诊断要求 + +第一阶段至少要能发现这些问题： + +- 模型导入缺失材质槽 +- 材质引用的纹理丢失 +- 场景对象引用了不存在的 Mesh +- 材质槽数量与 SubMesh 数量不匹配 +- 材质参数无法映射到当前后端 + +这些问题应至少在： + +- 导入阶段 +- Inspector +- Cook 阶段 + +给出明确提示。 + +## 推荐实现顺序 + +建议按下面顺序推进： + +1. 定义 `Material Asset` 资源结构 +2. 定义 `Mesh Asset` 资源结构 +3. 扩展 `MeshRenderer`，让它引用资源 GUID +4. 先打通 `glTF/.glb -> Mesh/Material Asset` +5. 打通对象级 Mesh/Material 指派 +6. 打通材质资源 Inspector +7. 建立 `Material -> simplepbr` 映射层 +8. 验证 Editor 与 Player 一致性 +9. 再考虑 `FBX` 与重导入增强 + +## 与第一阶段主线的关系 + +这份设计属于： + +-

也不是继续把材质逻辑散落在 `MeshRenderer` + +而是： + +**先建立 MetaCore 自己的 Mesh/Material 资源体系，再把模型导入和 `simplepbr` 渲染后端挂到这套资源体系两端。** + +这是让 MetaCore 真正形成“模型导入 -> 材质编辑 -> 场景搭建 -> Player 渲染”闭环的关键一步。 diff --git

+``` + +这里必须把两件事分清楚： + +1. **Editor 项目工作目录** +2. **交付运行时目录** + +第一阶段不能再让 `Player` 长期依赖开发期目录的偶然结构或临时 fallback 才能运行。 + +## 当前代码基础 + +当前仓库里已经有较好的基础： + +- `MetaCore.project.json` +- Scene 二进制 package 方向 +- Package 服务 +- Cook 服务 +- `CookManifest` +- Player 能读取项目和启动场景 +- RuntimeData 已有独立二进制文档和项目级 runtime 配置 + +这说明第一阶段不是没有打包基础，而是还缺一套清晰的“交付工作流定义”。 + +当前最需要解决的是： + +- 什么内容属于交付包 +- Cook 输出和源包之间的关系 +- Player 在交付态下应该从哪里加载内容 +- clean machine 验证应如何定义 + +## 第一阶段设计目标 + +第一阶段打包与交付工作流要满足： + +- 开发者能从一个项目构建出独立 Windows 客户端 +- 客户端不依赖 Editor 才能运行 +- 启动场景正确加载 +- 场景依赖资源正确带出 +- UI 资源可带出 +- Runtime 配置可带出 +- clean machine 上可运行 + +## 第一阶段角色划分 + +### 1. 项目工作目录 + +这是开发期使用的目录，包含： + +- `Assets` +- `Scenes` +- `Runtime` +- `Library` +- `MetaCore.project.json` + +这部分是创作环境，不是最终交付目录。 + +### 2. Cook 输出目录 + +这是中间产物目录，用于： + +- 存放 cooked 资源 +- 存放 cooked scene +- 存放依赖清单 + +第一阶段建议继续使用： + +- `Library/Cooked/Windows` + +### 3. 打包输出目录 + +这是最终交付目录。 + +第一阶段建议显式区分出来，例如： + +- `Build/Windows/` + +里面应包含： + +- `MetaCorePlayer.exe` +- 运行时内容目录 +- 项目 runtime 描述 +- 必需依赖文件 + +## 第一阶段推荐交付目录结构 + +建议第一阶段打包后输出结构类似： + +```text +Build/Windows// + MetaCorePlayer.exe + Content/ + Scenes/ + Assets/ + UI/ + Runtime/ + Project/ + MetaCore.runtimeproject +``` + +第一阶段名称可以调整，但结构职责必须清晰。 + +## 第一阶段必须打包的内容 + +### 1. 启动场景 + +必须带出项目定义的 `startup_scene` 对应的 cooked scene。 + +### 2. 场景依赖资源 + +至少要带出： + +- Mesh 资源 +- Material 资源 +- Texture 资源 +- Prefab 资源 +- Scene 引用的 UI 资源 + +### 3. 运行时配置 + +如果项目使用 RuntimeData 或其他运行时配置，则应带出： + +- `ProjectRuntime.mcruntimecfg` +- `DataSources.mcruntime` +- `Bindings.mcruntime` +- 后续 UI runtime 配置 + +### 4. 项目运行时描述 + +建议打包时生成一个“运行时项目描述”，用于告诉 `Player`： + +- 启动场景在哪里 +- 内容根目录在哪里 +- runtime 配置在哪里 +- UI 资源在哪里 + +这和开发期的 `MetaCore.project.json` 不必完全相同。 + +## 项目描述与运行时描述分离建议 + +这是第一阶段很关键的一个设计点。 + +### 开发期项目描述 + +例如： + +- `MetaCore.project.json` + +它更适合： + +- 可读 +- 面向编辑器 +- 面向开发期目录 + +### 运行时项目描述 + +建议打包时生成一个更面向交付的二进制或轻量配置文件，例如： + +- `MetaCore.runtimeproject` + +它更适合： + +- 面向 Player +- 面向 cooked/packaged 内容 +- 不依赖开发目录结构 + +第一阶段不一定要把这层做得很复杂，但“开发期描述”和“交付期描述”最好现在就区分。 + +## Cook 的职责 + +第一阶段 Cook 应明确负责： + +- 把源 package 复制或转换为运行时可消费输出 +- 建立 `CookManifest` +- 确定资源 GUID 与 cooked 路径关系 +- 为打包阶段提供可收集依赖的基础 + +### Cook 不是最终打包 + +这两层要分开： + +- Cook：生成内容 +- Package/Build：组织交付目录、复制 Player、拼装最终产物 + +## 打包流程建议 + +第一阶段推荐下面这条顺序： + +1. 解析项目描述 +2. 确定启动场景 +3. Cook 启动场景 +4. 递归收集依赖资源并 Cook +5. Cook UI 资源 +6. 收集 Runtime 配置 +7. 生成运行时项目描述 +8. 复制 `MetaCorePlayer.exe` +9. 组装交付目录 +10. 运行最小验证 + +## 第一阶段 Player 行为建议 + +打包后的 `Player` 不应默认去猜开发期路径。 + +建议优先行为： + +- 读取与自身同目录或指定参数下的运行时项目描述 +- 根据运行时项目描述找到： + - 启动场景 + - 内容根目录 + - Runtime 配置 + - UI 资源 + +### 仅在开发态允许 fallback + +例如： + +- 直接运行仓库里的 `TestProject` +- 自动猜测 `MetaCore.project.json` + +这类行为可以保留给开发便利，但不应成为交付态主路径。 + +## 场景与资源的打包策略 + +第一阶段建议： + +- Scene 以 cooked scene 文件形式带出 +- 资源以 cooked asset 文件形式带出 +- Scene 中只保存 GUID/引用关系 +- Player 运行时通过 runtime 内容索引解析资源 + +不要让交付态仍然需要访问源文件或编辑器期 package 路径推断逻辑。 + +## UI 的打包策略 + +如果第一阶段引入正式 UI 资源工作流，则打包时应同样带出： + +- UI 文档 +- UI 引用图片资源 +- 必要字体资源 + +Scene 或运行时项目描述应能定位到这些 UI 内容。 + +## RuntimeData 的打包策略 + +RuntimeData 在第一阶段不再是主线，但如果项目启用它，打包时必须作为正式交付内容处理： + +- runtime project 配置 +- source / binding 配置 +- 必要的 replay 文件或外部连接参数 + +注意： + +- 开发态的调试 fallback 不应进入正式交付流程 + +## clean machine 验证 + +这是第一阶段打包能力是否成立的真正验收标准。 + +### 验证目标 + +在没有源码、没有编辑器、没有开发期目录结构假设的机器上，最终产物应能： + +- 启动 +- 读取运行时项目描述 +- 加载启动场景 +- 正确加载资源 +- 正确显示 UI +- 如果配置了 RuntimeData，则能正确加载相关配置 + +### 最低验证方式 + +第一阶段至少要有一条明确流程： + +- 将打包目录复制到 clean machine 或近似隔离环境 +- 启动 `MetaCorePlayer.exe` +- 验证项目主界面和主场景 + +## 错误与诊断 + +交付态必须能对这些问题给出明确提示： + +- 启动场景缺失 +- cooked 资源缺失 +- UI 文档缺失 +- runtime 配置缺失 +- 运行时项目描述损坏 + +错误不应只表现为黑屏或静默失败。 + +第一阶段至少应做到： + +- 日志输出 +- 控制台/日志文件 +- 基础错误分类 + +## 推荐实现顺序 + +建议按下面顺序推进： + +1. 固定运行时项目描述结构 +2. 固定交付目录结构 +3. 打通 Scene 与资源依赖收集 +4. 打通 UI 资源带出 +5. 打通 Runtime 配置带出 +6. 复制 Player 和组装交付目录 +7. 做 clean machine 验证 +8. 再补增量构建与更细的诊断 + +## 第一阶段 Definition of Done + +下面这些成立时，才能认为第一阶段打包与交付工作流真正成立： + +- 从项目可以生成独立 Windows 输出目录 +- 输出目录包含 Player 和项目必需内容 +- Player 不依赖 Editor 即可运行 +- 启动场景能正确加载 +- 资源和 UI 能正确显示 +- Runtime 配置能正确读取 +- clean machine 验证通过 + +## 与整体路线的关系 + +这份文档对应第一阶段中的： + +- `M4 UI、持久化与打包循环` + +它的位置必须在： + +- 项目系统 +- 资源导入 +- 场景编辑 +- 材质与光照 +- UI 资源工作流 + +之后。 + +只有这些内容工作流成立后，打包才有意义。 + +## 最终建议 + +第一阶段不要把“能运行 Player”误认为“完成打包”。 + +真正的打包与交付能力，应当是： + +**能把一个项目稳定转换成独立运行的 Windows 客户端，并在脱离编辑器和源码环境后仍能正确加载场景、资源、UI 和运行时配置。** + +这一步做实之后，MetaCore 才算真正具备了“项目可交付”的引擎特征。 diff --git a/docs/designs/metacore-phase1-foundation-checklist-and-acceptance-matrix.md b/docs/designs/metacore-phase1-foundation-checklist-and-acceptance-matrix.md new file mode 100644 index 0000000..3c20644 --- /dev/null +++ b/docs/designs/metacore-phase1-foundation-checklist-and-acceptance-matrix.md @@ -0,0 +1,479 @@ +# MetaCore 第一阶段引擎基础功能总清单与验收矩阵 + +生成时间：2026-03-28 +状态：草案 +范围：第一阶段引擎基础主线 + +## 目的 + +这份文档用于把前面已经形成的多份设计文档，收敛成一份真正可执行的总表。 + +它要解决的问题很直接： + +- 第一阶段到底有哪些基础功能块 +- 哪些是 `P0 / P1 / P2` +- 每一项做到什么程度才算完成 +- 每一项应该如何验收 + +这份文档不替代前面的专项设计，而是作为： + +- 排期总表 +- 阶段验收清单 +- 团队对齐基线 + +## 使用方式 + +建议后续所有第一阶段推进，都以这份文档作为总入口： + +- 想看为什么这样做：回到对应专项设计文档 +- 想排开发顺序：看这里的优先级 +- 想判断一项是否完成：看这里的 `Definition of Done` +- 想做测试和验收：看这里的“验证方式” + +## 优先级定义 + +### P0 + +第一阶段主线阻塞项。 +不做完，MetaCore 还不能被视为“可用于开发项目的引擎”。 + +### P1 + +紧随 P0 的高价值能力。 +不一定是主线第一步，但缺了会明显影响生产力与交付质量。 + +### P2 + +重要，但应建立在 P0/P1 成立之后。 +典型是数字孪生增强、更多适配器、更多格式和更深能力。 + +## 总体完成标准 + +MetaCore 第一阶段只有在下面这句话成立时，才算真正完成： + +**开发者能够使用 MetaCore 完成一个 Windows 工业三维应用的项目创建、资源导入、场景搭建、材质与光照编辑、UI 配置、保存打开、打包交付，并在此基础上接入第一版 RuntimeData。** + +## 总清单与验收矩阵 + +### 1. 项目系统 + +优先级：`P0` + +#### 范围 + +- 项目创建/打开 +- `MetaCore.project.json` +- 项目目录结构 +- 启动场景 +- Editor / Player 围绕项目工作 + +#### Definition of Done + +- 能稳定定位项目根目录 +- `MetaCore.project.json` 能被一致读取和保存 +- 启动场景行为在 Editor 和 Player 中一致 +- 样板项目目录结构固定可理解 + +#### 验收方式 + +- 从不同工作目录启动仍能正确打开项目 +- 修改启动场景后保存，再次打开结果一致 +- 坏项目描述文件能给出明确报错 + +#### 相关文档 + +- [metacore-product-plan.md](D:/MetaCore/docs/designs/metacore-product-plan.md) +- [metacore-phase1-implementation-plan.md](D:/MetaCore/docs/designs/metacore-phase1-implementation-plan.md) +- [metacore-m1-m2-detailed-task-breakdown.md](D:/MetaCore/docs/designs/metacore-m1-m2-detailed-task-breakdown.md) + +### 2. 资源数据库与导入循环 + +优先级：`P0` + +#### 范围 + +- 资产元数据 +- Asset Database +- Import Pipeline +- Reimport +- Package 基础 + +#### Definition of Done + +- 导入后的资源进入 Asset Database +- 每个资源有稳定 GUID +- 资源能在 Project 面板中出现 +- 资源能被重新导入而不破坏基础引用 + +#### 验收方式 + +- 导入一个模型后能在资源列表中找到 +- 删除/修改源文件时系统给出明确反馈 +- 重导入后场景引用尽量保持稳定 + +#### 相关文档 + +- [metacore-m1-m2-detailed-task-breakdown.md](D:/MetaCore/docs/designs/metacore-m1-m2-detailed-task-breakdown.md) +- [metacore-project-panel-asset-browser-design.md](D:/MetaCore/docs/designs/metacore-project-panel-asset-browser-design.md) + +### 3. `glTF/.glb` 首批导入器 + +优先级：`P0` + +#### 范围 + +- `.glb` +- `.gltf + 外部资源` +- 节点层级 +- 材质抽取 +- 贴图抽取 +- 导入结果文档 + +#### Definition of Done + +- 导入一个 `glTF/.glb` 文件后，生成正式 Mesh / Material / Texture 资产 +- 保留节点层级描述 +- 可将模型资源拖入场景生成对象树 +- 重导入默认尽量保持 GUID 稳定 + +#### 验收方式 + +- 单网格、单材质样例导入成功 +- 多材质、多层级样例导入成功 +- 场景保存重开后模型实例仍有效 + +#### 相关文档 + +- [metacore-gltf-glb-importer-design.md](D:/MetaCore/docs/designs/metacore-gltf-glb-importer-design.md) + +### 4.
