+# 项目背景：UE5 + 3D LED 大屏展示系统
+
+> 供其他 AI 快速了解项目背景和当前状态。
+> 最后更新：2026-04-14
+
+---
+
+## 一、项目定位
+
+这不是一个普通的桌面地球应用，而是一套**领导演示用的 3D 沉浸式展示系统**。
+
+核心逻辑：
+- 态势感知数据（超算、海缆、卫星）是内容
+- 3D LED 大屏 + 实时渲染 + 动捕交互是"醋"——没有它，内容再好也只是普通屏幕
+- 主要受众：领导/决策层，注重视觉冲击力
+
+---
+
+## 二、硬件配置
+
+| 硬件 | 规格 | 说明 |
+|------|------|------|
+| 3D LED 大屏 | 5.12m × 2.88m，P1.538mm，被动偏振式 | 观众戴无源 3D 眼镜（≤18g），60Hz 即可出稳定 3D |
+| 渲染工作站 | 双路国产 X86 CPU + RTX 5090 32GB | 驱动 UE5 实时渲染 |
+| 视频处理器 | 随屏配套（品牌待确认） | 接收 GPU 信号，驱动 LED 墙 |
+| 动捕摄像头 | RGB 摄像头 ×2，4K，直连电脑 | 无穿戴姿态识别 |
+| 音响 | 解码功放 + 吸顶喇叭 ×5 + 低音炮 | 配套 |
+
+---
+
+## 三、软件架构
+
+```
+摄像头（×2，直连）
+    ↓ 动捕插件（供应商提供 UE5 插件）
+UE5 主程序（我们开发）
+    ├── Cesium 地球（实时渲染）
+    ├── 超算数据点（可交互）
+    ├── 其他可交互物件
+    └── 立体渲染输出
+         ↓ 视频信号（格式待确认）
+    视频处理器（随屏配套）
+         ↓ LED 驱动信号（行偏振）
+    5m 被动偏振 3D LED 大屏
+```
+
+---
+
+## 四、分工
+
+| 部分 | 谁做 | 状态 |
+|------|------|------|
+| LED 屏体 + 视频处理器 | 屏幕供应商 | 采购中 |
+| 动捕插件（UE5 插件形式） | 动捕供应商 | 待交付 |
+| UE5 基础工程（关卡+角色+动捕绑定） | 动捕供应商 | 待交付 |
+| 地球场景 + 数据可视化 + 交互逻辑 | 我们（本项目） | 开发中 |
+| 后端数据接口 | 我们（本项目） | 已完成 |
+| 其他 9 个定制 3D 资产和动画 | 3D 内容供应商 | 采购中 |
+
+---
+
+## 五、动捕交互方式
+
+**交付形式（已确认）**：
+- 供应商给我们**完整 UE5 工程**，包含：
+  - 视频动捕插件
+  - 已配好绑定和重定向的 3D 角色
+  - 3D 模型和动画资产
+  - 接两台摄像头即可直接运行
+- **我们的任务**：把他们工程的内容（插件 + 角色 + 资产）**迁移进我们的 `ue_client/` 工程**，然后把角色动作映射到地球操作
+
+**待确认**：角色动作的触发点是什么形式？
+- 蓝图 Custom Event（如 `OnGestureRotate`）？
+- AnimNotify？
+- 需要我们自己判断骨骼姿态？
+
+**交互目标（一期）**：
+1. 手势旋转地球
+2. 手势缩放地球
+3. 手势指向/确认 → 选中数据点，弹出信息卡
+4. 鼠标作为备用输入（始终可用）
+
+---
+
+## 六、立体渲染
+
+**待确认**：
+1. 供应商基础工程里是否已配好立体渲染输出？
+2. 如果没有：视频处理器接受什么格式？（Side-by-Side / Top-Bottom / 其他）
+3. 给供应商的文件形式：UE5 工程 / .exe / 视频文件 / 直连实时输出？
+
+**已准备**：`StereoRenderingManager.h/.cpp` 支持运行时切换 SbS/TbB，格式确认后直接启用。
+
+---
+
+## 七、已完成的代码

+# UE5 客户端手动操作指南
+
+> 本指南对应 `ue_client/` 目录下已生成的所有代码和配置。  
+> 代码已写好，你只需要做编辑器里的点击操作。  
+> 遇到红色错误先看文末"常见问题"章节。
+
+---
+
+## 前置条件
+
+| 软件 | 版本 | 下载地址 |
+|------|------|---------|
+| Unreal Engine | **5.3** | Epic Games Launcher → Library → 5.3 |
+| Cesium for Unreal | 最新 | 直接在下一步从 Marketplace 安装 |
+| Visual Studio | 2022 Community | visualstudio.microsoft.com（安装 C++ 游戏开发工作负载） |
+
+> **注意**：Cesium for Unreal 必须先安装，否则代码会编译失败。
+
+---
+
+## 第一阶段（Phase A）：本地演示版（不需要后端）
+
+### 步骤 1：安装 Cesium for Unreal
+
+1. 打开 **Epic Games Launcher**
+2. 顶部切换到 **Unreal Engine** 选项卡
+3. 左侧点击 **Fab**（原 Marketplace，已改名）→ 搜索 `Cesium for Unreal`
+4. 点击 **免费获取**（Free），然后点击 **安装到引擎** → 选择 5.3
+5. 等待安装完成
+
+---
+
+### 步骤 2：打开项目
+
+1. 打开 **Epic Games Launcher** → **Unreal Engine** → **Library**
+2. 找到 5.3，点击右侧 **Launch** 旁边的下拉箭头 → **Browse**
+3. 导航到 `planet/ue_client/`，选择 `PlanetClient.uproject`，点击打开
+4. UE 会提示"缺少模块，需要重新编译" → 点击 **Yes**
+5. 等待编译完成（首次约 5-10 分钟）
+
+> 如果编译报错：见文末"常见问题 → 编译错误"
+
+---
+
+### 步骤 3：创建新关卡
+
+1. 菜单栏 → **File** → **New Level**
+2. 选择 **Empty Level**（空关卡）
+3. 保存：**File** → **Save Current Level As**  
+   路径：`Content/Maps/`，名称：`EarthMap`
+4. 点击 **Save**
+
+---
+
+### 步骤 4：添加 Cesium 地球
+
+1. 顶部菜单栏 → **Cesium**（如果没有此菜单，说明插件未激活：Edit → Plugins → 搜索 Cesium → 勾选 Enable → 重启）
+2. 在 Cesium 面板里点击 **Add Blank 3D Tiles Tileset** — 这会自动在场景里添加：
+   - `CesiumGeoreference` Actor
+   - `Cesium3DTileset` Actor（地球瓦片）
+3. 再点击 **Add Cesium ion Bing Maps Aerial** 添加卫星影像底图（需要免费 Cesium ion 账号）
+
+> 如果没有 Cesium ion 账号：Cesium 菜单 → Connect to Cesium ion → 注册免费账号
+
+---
+
+### 步骤 5：添加相机 Pawn
+
+1. 菜单栏 → **Cesium** → 找到 **Dynamic Pawn**（名称可能是 `CesiumFlyToComponent` 相关的 Blueprint）  
+   **或者**：Content Browser → 顶部搜索框输入 `DynamicPawn` → 找到插件内容里的 `DynamicPawn` → 拖入场景
+2. 在 **Outliner** 面板里点击刚拖入的 `DynamicPawn`
+3. 在 **Details** 面板里，找到 **Auto Possess Player** → 改为 **Player 0**
+
+> 这样游戏启动时摄像机会自动使用这个可飞行的地球相机。
+
+---
+
+### 步骤 6：配置 GameMode
+
+1. 菜单栏 → **Window** → **World Settings**（如果没有，也可以在 Details Panel 里找）
+2. 在 **World Settings** 面板里找到 **Game Mode Override**
+3. 点击下拉框 → 搜索 `PlanetGameMode` → 选择它
+4. 找到 **Default Pawn Class** → 改为上一步拖入的 `DynamicPawn`
+
+---
+
+### 步骤 7：创建 ComputePoint Blueprint
+
+这步把我写的 C++ 类包装成可以在编辑器里配置材质的 Blueprint。
+
+1. **Content Browser** → 空白处右键 → **Blueprint Class**
+2. 搜索父类：输入 `ComputePointActor` → 找到 `AComputePointActor` → 点击 **Select**
+3. 命名为 `BP_ComputePointActor`，保存到 `Content/Blueprints/`
+
+**配置 BP_ComputePointActor 的网格和材质：**
+
+4. 双击打开 `BP_ComputePointActor`
+5. 在左侧 **Components** 面板里点击 `SphereMesh`
+6. 在右侧 **Details** 面板里找到 **Static Mesh** → 点击下拉 → 搜索 `Sphere` → 选择 **Engine/BasicShapes/Sphere**
+7. 找到 **Material** → 点击下拉 → 搜索 `M_Basic_Wall` 或者创建新材质（见下方）
+
+**创建三种状态的材质（颜色点即可）：**
+
+8. Content Browser → 右键 → **Material** → 命名 `M_PointNormal`
+   - 双击打开 → 右键空白区域 → 搜索 `Constant3Vector` → 连接到 `Base Color`
+   - 颜色设为橙色：`(1.0, 0.4, 0.0)`
+   - 保存
+
+9. 同样方式创建 `M_PointHovered`（颜色白色 `1,1,1`）和 `M_PointSelected`（颜色青色 `0,1,1`）
+
+**回到 BP_ComputePointActor：**
+
+10. 在 **Details** 面板里：
+    - **Normal Material** → 选 `M_PointNormal`
+    - **Hovered Material** → 选 `M_PointHovered`
+    - **Selected Material** → 选 `M_PointSelected`
+    - **Point Scale** → `80000`（根据实际效果调整）
+11. 点击左上角 **Compile** → **Save**
+
+---
+
+### 步骤 8：放置 DataManager 并配置
+
+1. **Content Browser** → 右键 → **Blueprint Class** → 父类搜索 `PlanetDataManager` → 选择 `APlanetDataManager`
+2. 命名为 `BP_PlanetDataManager`，保存到 `Content/Blueprints/`
+3. 将 `BP_PlanetDataManager` **拖入场景**（Outliner 里会出现它）
+4. 在 Outliner 里点击它 → 在 **Details** 面板里配置：
+   - **Use Local Mock Data** → ✅ **勾选**（Phase A 不需要后端）
+   - **Mock Data Path** → 留空（代码会自动找 `Content/Data/mock_compute_points.json`）
+   - **Compute Point Class** → 选择 `BP_ComputePointActor`
+   - **Point Altitude Meters** → `50000`（海拔 50km，可调）
+
+---
+
+### 步骤 9：测试 Phase A
+
+1. 点击顶部工具栏绿色 **Play** 按钮（或 Alt+P）
+2. 地球应该加载卫星影像
+3. 应该看到 10 个橙色球体分布在地球上（对应 mock JSON 里的 TOP500 超算）
+4. 鼠标移到球体上 → 变白色（Hover）
+5. 点击球体 → 变青色（Selected）
+
+**验证通过标准：**
+- [x] 地球可见
+- [x] 橙色球体出现在正确位置（美国、日本、荷兰、芬兰等）
+- [x] 悬停变色
+- [x] 点击变色
+
+---
+
+## 第二阶段（Phase B）：连接真实后端
+
+### 步骤 10：确认后端新接口可用
+
+后端代码已添加新路由，先验证它已经运行：
+
+```bash
+# 在 WSL 或终端里
+curl http://localhost:8000/api/v1/ue/status
+```
+
+应该返回类似：
+```json
+{"ok": true, "server_time": "...", "compute_points_count": 500, ...}
+```
+
+如果 curl 失败：
+- 检查 `planet.sh` 是否在运行（`./planet.sh start`）
+- 检查 WSL2 → Windows 的网络：在 UE 里使用 `172.x.x.x`（WSL 网关地址）而不是 `localhost`
+
+---
+
+### 步骤 11：获取 WSL2 → Windows 的正确 IP
+
+在 WSL 终端里运行：
+
+```bash
+cat /etc/resolv.conf | grep nameserver | awk '{print $2}'
+```
+
+记下这个 IP（例如 `172.22.32.1`）。
+
+---
+
+### 步骤 12：切换 DataManager 到实时模式
+
+1. 在 Outliner 里点击 `BP_PlanetDataManager`
+2. Details 面板里：
+   - **Use Local Mock Data** → **取消勾选**
+   - **Backend Base URL** → 填入 `http://172.22.32.1:8000`（你的实际 WSL IP）
+3. 重新 Play → DataManager 会通过 HTTP 拉取真实数据
+
+---
+
+### 步骤 13：绑定点击事件显示信息卡（可选，需要 UMG）
+
+这步是可选的，需要创建一个 Widget Blueprint 来显示选中点的信息。
+
+1. Content Browser → 右键 → **User Interface** → **Widget Blueprint**
+2. 命名为 `WBP_PointInfo`
+
+**设计 Widget 布局：**
+
+3. 双击打开 `WBP_PointInfo`
+4. 从左侧 **Palette** 拖入以下控件到画布：
+   - `Canvas Panel`（容器，设置为全屏）
+   - `Border`（右下角定位，用作信息卡背景，宽 300，高 200）
+   - `Text Block` × 4（名称、排名、算力、国家）
+
+**绑定事件（Blueprint 里操作）：**
+
+5. 打开 `BP_PlanetDataManager` 的 Event Graph
+6. 找到 **BeginPlay** 节点
+7. 拖出线 → 搜索 **Bind Event to On Point Selected**（这是我在 PlayerController 里定义的委托）
+
+> 具体蓝图连线：从 PlayerController 获取 OnPointSelected → Bind → 在回调里 Create Widget WBP_PointInfo → Add to Viewport → Set 各个文本
+

+## 后端新接口一览
+
+后端已新增以下接口（无需认证，直接访问）：
+
+| 接口 | 说明 |
+|------|------|
+| `GET /api/v1/ue/status` | 健康检查 + 各数据源数量 |
+| `GET /api/v1/ue/compute-points` | TOP500 超算数据（平铺 JSON） |
+| `GET /api/v1/ue/landing-points` | 海缆登陆点（平铺 JSON） |
+| `GET /api/v1/ue/cables` | 海缆路由几何（segments 数组） |
+| `GET /api/v1/ue/satellites` | 卫星 TLE 数据 |
+
+---
+
+## 常见问题
+
+### Q: 编译报错 "Cannot open include file: CesiumGeoreference.h"
+**A:** Cesium for Unreal 没有正确安装，或者没有在 `.uproject` 里启用。检查：
+1. Epic Launcher → 插件是否安装到 5.3
+2. `PlanetClient.uproject` 里 `Plugins` 数组是否有 `CesiumForUnreal: true`
+3. UE 编辑器 → Edit → Plugins → 搜索 Cesium → 确认已勾选 Enabled
+
+### Q: Play 之后没有看到橙色球体
+**A:** 按以下顺序排查：
+1. Output Log（Window → Output Log）里搜索 `PlanetDataManager` — 查看是否有报错
+2. 检查 `BP_PlanetDataManager` 的 Details → **Compute Point Class** 是否已设置为 `BP_ComputePointActor`
+3. 检查 **Mock Data Path** 是否正确（留空则自动用 `Content/Data/mock_compute_points.json`）
+4. 检查 **Use Local Mock Data** 是否已勾选
+
+### Q: 地球是灰色的没有卫星影像
+**A:** 需要 Cesium ion 账号：
+1. Cesium 菜单 → Connect to Cesium ion
+2. 注册免费账号并授权
+3. 重新添加 **Cesium ion Bing Maps Aerial** tileset
+
+### Q: WSL2 里的后端 UE 无法访问（Phase B）
+**A:** WSL2 和 Windows 是不同网络命名空间。方法：
+1. 在 WSL 里运行 `ip route show default | awk '{print $3}'` — 这是 Windows 主机的 IP
+2. 后端绑定到 `0.0.0.0:8000`（检查 `uvicorn` 启动参数，应已如此配置）
+3. 在 UE 的 DataManager 里填写这个 IP 而不是 `localhost`
+
+### Q: TransformLongitudeLatitudeHeightPositionToUnreal 不存在
+**A:** Cesium for Unreal API 在不同版本有变化。如果编译报此错，将 `PlanetDataManager.cpp` 里的调用改为：
+```cpp
+// Cesium for Unreal v1.x 的旧 API：
+FVector WorldPos = Georeference->TransformLongitudeLatitudeHeightToUnreal(
+    Pt.Longitude, Pt.Latitude, PointAltitudeMeters);
+
+// 或者通过 GeoTransforms：
+#include "CesiumGlobeAnchorComponent.h"
+// ... 见 Cesium 文档
+```
+
+### Q: 点击球体没有反应
+**A:**
+1. 确认 `SphereMesh` 上 **Collision Presets** 不是 `NoCollision`
+   - 打开 `BP_ComputePointActor` → 点击 `SphereMesh` → Details → Collision → 改为 `BlockAllDynamic`
+2. 确认 PlayerController 的 `bEnableClickEvents = true`（代码里已设置）
+3. Output Log 里搜索是否有输入相关报错
+
+---
+
+## 下一步（一期完成后）
+
+| 功能 | 说明 |
+|------|------|
+| 海缆路径渲染 | `/api/v1/ue/cables` 已就绪，需要在 UE 里用 Spline 绘制 |
+| 信息卡 UMG | 创建 Widget Blueprint 并在 PlayerController OnPointSelected 里显示 |
+| WebSocket 实时更新 | 后端已有 WebSocket，UE 端需要使用 WebSockets 插件 |
+| 卫星轨迹 | TLE 数据已就绪，需要在 UE 里做轨道传播计算 |

+# UE5 客户端 — 待供应商回复的 TODO
+
+> 以下两个问题答复后，对应代码可在一天内完成。
+> 其余所有代码均已写好，不依赖这两个答案。
+
+---
+
+## TODO-1：视频处理器输入格式
+
+**等待信息**：LED 屏配套视频处理器（如诺瓦星云）接受什么 3D 信号格式？
+
+| 可能答案 | 对应操作 |
+|---------|---------|
+| Side-by-Side（左右并排） | `StereoRenderingManager.cpp` 里 `EnableStereo` 的 `SideBySide` 分支已写好，直接启用 |
+| Top-Bottom（上下叠加） | 同上，切换到 `TopBottom` 分支 |
+| 行交错（行偏振直驱） | 需要新写一个 PostProcess Material，把左右眼奇偶行合并输出 |
+| 私有协议 | 需要供应商提供 UE5 插件或信号格式文档 |
+
+**代码位置**：
+```
+ue_client/Source/PlanetClient/StereoRenderingManager.h  — 第 8-18 行 TODO 注释
+ue_client/Source/PlanetClient/StereoRenderingManager.cpp — EnableStereo() 函数
+```
+
+**需要同时确认**：
+- 视频处理器品牌和型号
+- 屏幕物理分辨率（用于配置 UE5 输出分辨率）
+- 3D 启用时是否需要特殊信号时序（如 3D Frame Packing）
+
+---
+
+## TODO-2：动捕角色接入
+
+**已确认**：
+- **本周末前**：供应商交付含动捕插件 + 3D 角色（已配好绑定和重定向）的基础 UE5 工程
+  - 接入两台摄像头，4080 以上显卡即可直接运行动捕调试
+- **之后尽快**：动画资产单独交付，复制到工程 Content/ 目录即可直接调用
+- **我们的任务**：把他们工程内容迁移进 `ue_client/`，把角色动作映射到地球操作
+
+---
+
+### 阶段 A：拿到基础工程后（本周末）
+
+**迁移步骤**：
+
+1. **迁移动捕插件**
+   - 从供应商工程 `Plugins/` 拷到 `ue_client/Plugins/`
+   - `PlanetClient.uproject` 的 `Plugins` 数组添加插件条目（`Enabled: true`）
+   - `PlanetClient.Build.cs` 的 `PublicDependencyModuleNames` 加插件模块名
+
+2. **迁移角色**
+   - 把角色 Blueprint、动画、骨骼网格从供应商 `Content/` 拷到 `ue_client/Content/`
+   - 在关卡里放置角色 Actor，确认摄像头接入后能正常驱动
+
+3. **接入动作触发（关键，看到工程后确认方式）**：
+
+| 需要确认的内容 | 用途 |
+|-------------|------|
+| 角色动作怎么暴露给外部？ | Blueprint Custom Event / AnimNotify / 骨骼姿态变量？ |
+| 手势集合有哪些？ | 填写 `EMotionGesture` 枚举，配置 `FMotionActionMapping` |
+| 是否持续输出旋转增量？ | 旋转地球用"持续增量"还是"离散手势触发" |
+| 插件模块名称（`ModuleName`）| 加入 `Build.cs` 依赖 |
+
+**拿到工程后（我来做）**：
+- 用插件实际 API 实现 `UMotionCaptureReceiver` 子类
+- 在 `PlanetPlayerController::BeginPlay` 里取消注释 `BindMotionCaptureEvents()`
+
+**代码位置（接口已预留）**：
+```
+ue_client/Source/PlanetClient/MotionCaptureInterface.h   — 基类和手势枚举
+ue_client/Source/PlanetClient/PlanetPlayerController.cpp — BindMotionCaptureEvents()
+ue_client/Source/PlanetClient/PlanetClient.Build.cs      — TODO 注释处加插件模块名
+ue_client/PlanetClient.uproject                          — Plugins 数组加插件条目
+```
+
+---
+
+### 阶段 B：动画资产到位后
+
+- 把供应商提供的动画资产直接复制到 `ue_client/Content/` 对应目录
+- 在 `PlanetDataManager` / 场景 Actor 里引用这些资产即可调用
+
+---
+
+## 答复到位后的操作清单
+
+拿到答案后告诉我，我来：
+
+1. **视频处理器格式** → 配置 `StereoRenderingManager`，把 `bAutoEnableOnPlay` 改为 `true`，写进 setup guide
+2. **动捕插件** → 插件放入 `ue_client/Plugins/`，实现 `UMotionCaptureReceiver` 子类对接插件 API，更新 `Build.cs` 和 `.uproject`
