 - [Three.js SpriteMaterial](https://threejs.org/docs/pages/SpriteMaterial.html)

+## 天球背景资源与星体数据来源
+
+为避免把“视觉背景”和“可计算天体位置”混为一谈，本方案明确分成两类资源：
+
+### 1. 背景资源：全天星图贴图
+
+用于 Phase 1 的“真实天空背景”。
+
+推荐优先来源：
+
+- NASA SVS 的 Tycho 全天星图
+  - [The Tycho Catalog Skymap - Version 2.0](https://svs.gsfc.nasa.gov/3572/)
+- NASA Deep Star Maps 2020
+  - SatelliteMap.space 在 credits 中明确提到其使用了 `NASA Deep Star Maps 2020 - High-resolution star field (1.7 billion stars from Gaia DR2)` 作为星空视觉资源
+  - 这说明行业内成熟实现并不一定直接渲染全部星表点，而很可能先使用一张高质量官方深空星图作为背景层
+- 如需后续替换，也可评估 ESA / Gaia 的全天 sky map 资源
+  - [Gaia DR3 stories](https://www.cosmos.esa.int/web/gaia/dr3-stories)
+
+建议要求：
+
+- 使用官方来源或官方衍生可复用资源
+- 等距矩形投影（equirectangular）
+- 坐标定义尽量明确为赤道坐标展开
+- 分辨率建议至少 `4k`
+- 颜色不要过亮，避免压过 Earth HUD 前景
+- 尽量优先选择官方天文机构已经生产好的深空图，而不是自行拼接低质量星空纹理
+
+建议本地资源目录：
+
+- `frontend/public/earth/assets/celestial/starmap_equatorial_4k.jpg`
+
+### 2. 位置数据：星表与天体计算
+
+用于 Phase 2+ 的“位置正确的星体”。
+
+推荐来源分两层：
+
+- 太阳、月亮位置
+  - 使用 [Astronomy Engine](https://github.com/cosinekitty/astronomy)
+- 恒星位置
+  - 第一优先：Hipparcos / Tycho
+    - [Hipparcos overview](https://www.cosmos.esa.int/web/Hipparcos)
+    - [Hipparcos catalogues](https://www.cosmos.esa.int/web/hipparcos/catalogues)
+  - 第二优先：Gaia
+    - [Gaia DR3 stories](https://www.cosmos.esa.int/web/gaia/dr3-stories)
+
+建议策略：
+
+- V1：背景球壳只用全天星图，不立即生成全量恒星点
+- V2：只挑选亮星（例如星等 `< 5.5`）生成恒星点层
+- V3：如果确实需要更丰富的星场，再逐步扩展到更深星等
+
+这样做的原因：
+
+- 背景球壳负责“天球真实感”
+- 亮星点负责“位置正确、可后续标注和高亮”
+- 不需要一开始就处理数十万甚至数百万颗星
+
+### 3. 对外部成熟实现的参考结论
+
+`SatelliteMap.space` 的公开 credits 提供了一个很有价值的参考样板：
+
+- 图形渲染使用 `TWGL.js`
+- 天文计算使用 `Skyfield` 与 `Astronomia`
+- 星空/天球视觉资源使用 `NASA Deep Star Maps 2020`
+
+这给本项目的启发是：
+
+- “真实感强的天球背景”完全可以先依赖官方高质量深空图
+- “位置正确的动态天体”则应依赖单独的天文计算链路
+- 没有必要在第一版就直接渲染完整星表
+
+因此本项目推荐继续坚持两层拆分：
+
+- 背景层：官方深空图 / 全天星图
+- 计算层：太阳、月亮与后续亮星点
+
+## 如何保证星体位置正确
+
+位置正确不是只看“图看起来像”，而是要统一参考系和转换链路。
+
+### 1. 统一坐标基准
+
+本方案推荐统一使用：
+
+- `J2000` 赤道坐标系作为恒星位置基准
+
+原因：
+
+- Hipparcos / Tycho 资料和大量天文可视化都容易映射到该基准
+- 太阳、月亮也可以通过 Astronomy Engine 转到同一坐标系
+- 这样背景、恒星点、太阳、月亮就能共用一套 sky orientation
+
+### 2. 背景贴图与点位必须使用同一展开逻辑
+
+如果背景球壳使用赤道坐标全天图，那么：
+
+- 亮星点也必须按赤道坐标贴到同一球面方向
+- 太阳/月亮 sprite 也必须按赤道坐标转换后落到同一 world-space
+
+否则会出现：
+
+- 背景银河带是对的
+- 但太阳/月亮或亮星点飘到不匹配的位置
+
+### 3. RA / Dec 到 Three.js 坐标的落点方式
+
+亮星点和日月方向最终都要转成单位球面向量。
+
+概念步骤：
+
+1. 读取赤经 `RA`
+2. 读取赤纬 `Dec`
+3. 转成弧度
+4. 映射到单位球面向量
+5. 再根据 Three.js 当前世界坐标定义做轴向映射
+
+参考公式：
+
+```text
+x = cos(dec) * cos(ra)
+y = sin(dec)
+z = cos(dec) * sin(ra)
+```
+
+实际接入 Three.js 时，需要做一次项目内坐标轴校准：
+
+- 验证 `RA = 0h`
+- 验证 `RA = 6h`
+- 验证北天极
+- 验证银河带主方向
+
+然后确定最终的：
+
+- `x/y/z` 对应 Three.js 哪个轴
+- 是否需要 `z` 取反
+- 是否需要整体再做一个固定 `rotation`
+
+建议把这层显式封装在：
+
+```js
+function equatorialToWorldVector(raRad, decRad)
+```
+
+不要把轴映射散落在不同模块里。
+
+### 4. 背景球壳与恒星点的关系
+
+推荐最终组合：
+
+- 背景层：全天星图球壳
+- 点位层：亮星点
+- 动态层：太阳 / 月亮
+
+这样有三个好处：
+
+- 背景层提供密集真实的天空纹理
+- 亮星点提供位置正确、可扩展的标注基础
+- 太阳/月亮提供与时间相关的真实动态对象
+
+## 数据与资源建议清单
+
+### 推荐首批引入资源
+
+1. 全天星图
+- 来源：NASA Tycho all-sky map
+- 用途：背景球壳纹理
+
+2. 月亮纹理
+- 用途：Phase 4 月相表现
+- 路径建议：
+  - `frontend/public/earth/assets/celestial/moon_albedo_2k.jpg`
+
+3. 太阳 glow 贴图
+- 用途：太阳 sprite halo
+- 路径建议：
+  - `frontend/public/earth/assets/celestial/sun_glow.png`
+
+### 推荐首批数据文件
+
+如果要上亮星层，建议新增一个预处理后的轻量数据文件：
+
+- `frontend/public/earth/assets/celestial/bright-stars.json`
+
+建议字段：
+
+```json
+[
+  {
+    "id": 32349,
+    "name": "Sirius",
+    "raDeg": 101.2875,
+    "decDeg": -16.7161,
+    "mag": -1.46,
+    "colorIndex": 0.00
+  }
+]
+```
+
+建议不要在浏览器里直接吞原始 Gaia 大表，而是先离线裁剪成：
+
+- 只保留亮星
+- 只保留渲染必需字段
+- JSON 或二进制轻量格式
+
+## 资源与数据实施路线
+
+### 路线 A：先做可用版本（推荐）
+
+1. 引入 NASA Tycho 全天图
+   - 或评估替换为更接近 SatelliteMap.space 路线的 `NASA Deep Star Maps 2020`
+2. 实现背景球壳
+3. 用 Astronomy Engine 计算太阳/月亮方向
+4. 暂不做亮星点
+
+优点：
+
+- 最快见效
+- 风险最低
+- 就能明显提升天球真实感
+
+### 路线 B：在 A 基础上增强
+
+1. 离线生成 `bright-stars.json`
+2. 浏览器端渲染亮星点
+3. 后续可加：
+   - 星座线
+   - 亮星名称
+   - 特定星体高亮
+
+优点：
+
+- 背景真实感和“位置正确的可交互星体”同时兼顾
+
+## 代码模块建议细化
+
+### 新增模块
+
+- `frontend/public/earth/js/celestial.js`
+  - 管理天球背景
+  - 管理太阳/月亮
+  - 管理亮星层（后续）
+
+- `frontend/public/earth/js/celestial-data.js`
+  - 资源路径
+  - 星图方向配置
+  - 亮星数据加载（后续）
+
+### 建议函数设计
+
+```js
+export function initCelestialLayer(scene)
+export function updateCelestialLayer(date)
+export function setCelestialVisibility(visible)
+export function disposeCelestialLayer()
+
+function loadStarMapTexture()
+function createSkySphere(texture)
+function createSunSprite()
+function createMoonSprite()
+function getSunEquatorialPosition(date)
+function getMoonEquatorialPosition(date)
+function equatorialToWorldVector(raRad, decRad)
+```
+
+### 推荐后续预处理脚本
+
+如要引入亮星层，建议单独做离线脚本：
+
+- `scripts/build_bright_stars.py`
+
+职责：
+
+- 从 Hipparcos / Tycho 源数据读取
+- 过滤亮星
+- 生成 `bright-stars.json`
+
+这样浏览器端只消费轻量结果，不承担大表解析成本。

+# Earth Real Terrain Plan
+
+## Goal
+
+将 Earth 页当前的“程序噪声假地形”替换成基于真实 DEM 的可用地形层，使 `地形 terrain` 开关真正显示全球海拔起伏，而不是占位效果。
+
+当前占位实现位于：
+
+- [earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js)
+
+具体问题：
+
+- `createTerrain()` 直接对球体顶点应用 `simplex noise`
+- 没有真实海拔数据来源
+- 没有分辨率分层
+- 没有和当前相机/视角配套的性能控制
+
+## Constraints
+
+本计划必须贴合当前 Earth 架构，而不是引入一套全新的地形引擎：
+
+- 地球主体仍然是一个 Three.js sphere
+- 海缆、登陆点、卫星、BGP 都已经建立在当前球体坐标系之上
+- 不能为了地形把整页改成 Cesium/MapLibre Globe 之类的全栈替换
+- 第一阶段优先做“真实可用”，不是一步到位做摄影测量级地形
+
+## Recommended Data Source
+
+### Primary recommendation
+
+使用公开的 Terrarium 编码高程瓦片作为浏览器端高度来源，第一阶段优先接入：
+
+- Mapzen/AWS `Terrarium` elevation tiles  
+  参考：[Mapzen terrain tile format / Terrarium](https://www.mapzen.com/blog/terrain-tile-service/)
+
+原因：
+
+- 已经是全球瓦片化高程
+- 浏览器端按 tile 请求，最适合当前 Earth 这种在线 globe
+- 编码简单稳定：
+  - `heightMeters = (R * 256 + G + B / 256) - 32768`
+- 不需要我们先离线拼整球 DEM
+
+### Data quality upgrade path
+
+如果后面第一阶段效果确认可用，再逐步升级到底层源：
+
+- Copernicus DEM GLO-30  
+  参考：[Copernicus DEM docs](https://documentation.dataspace.copernicus.eu/APIs/SentinelHub/Data/DEM.html)
+- 或用 Copernicus / SRTM / ASTER 等离线切成我们自己的 terrain tiles
+
+这条升级路径适合第二阶段，不建议一开始就直接自建全球瓦片服务。
+
+## Why Not Replace the Engine
+
+不建议为了地形直接切到 Cesium terrain / quantized mesh 引擎，原因：
+
+- 现有 Earth 业务对象都依附当前球面坐标
+- 切引擎会同时波及：
+  - 海缆绘制
+  - 卫星/轨迹
+  - BGP 标记
+  - HUD 与交互
+- 这是“重做一页”，不是“给地形层接真实数据”
+
+所以推荐路线是：
+
+- 保持当前 sphere globe
+- 为 sphere 增加真实高度位移层
+
+## Implementation Strategy
+
+分三期推进。
+
+### Phase 1 — Global Heightmap Terrain Overlay
+
+目标：
+
+- 地形层切换后显示真实海拔起伏
+- 全球范围可用
+- 性能可控
+
+做法：
+
+1. 新增 terrain 数据模块
+
+建议文件：
+
+- `frontend/public/earth/js/terrain.js`
+
+职责：
+
+- 选择 DEM zoom level
+- 请求 Terrarium tiles
+- 解码 tile 高程
+- 将高程重采样到当前地形球体网格
+
+2. 替换 `createTerrain()`
+
+当前：
+
+- 在 [earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js) 中同步生成噪声地形
+
+调整后：
+
+- `createTerrain()` 只负责创建 terrain mesh 骨架
+- 真正的顶点位移由 terrain 模块异步注入
+
+3. 第一阶段采用“整球低分辨率位移”
+
+不要一上来做动态 patch stitching。第一阶段更稳的办法是：
+
+- 保留一张全球 terrain sphere
+- 使用较低分辨率几何
+  - 例如 `SphereGeometry(radius, 192, 192)` 或 `256/256`
+- 运行时按一个固定地形 zoom（如 `z=4` 或 `z=5`）抓取覆盖全球的 Terrarium tiles
+- 将 tile 解码后重投影到经纬度采样网格
+- 将每个球面顶点按真实高度抬升
+
+这样第一阶段就能做到：
+
+- 有真实地形
+- 不需要复杂的局部 LOD
+- 不会让现有球体对象体系爆炸
+
+### Phase 2 — View-Aware Refinement
+
+目标：
+
+- 正面可见区域更精细
+- 背面与远处维持低成本
+
+做法：
+
+- 引入“基础全球地形 + 当前视角高分局部补丁”
+- 正面区域额外抓更高 zoom 的高程 tile
+- 只替换局部顶点位移或局部 overlay mesh
+
+这一阶段适合在第一阶段稳定后做。
+
+### Phase 3 — Normals / Shading / Terrain UX
+
+目标：
+
+- 地形不仅有起伏，还更好看、更可读
+
+包括：
+
+- 根据高度生成更合理的 normals
+- 调整 terrain material，使山脉/高原更易读
+- 可选加入：
+  - hillshade
+  - contour lines
+- snowline / bathymetry tint
+
+## Calibration Overlay Before More Terrain Tuning
+
+在当前项目里，terrain 看起来“不像真地形”，不一定只是 DEM 或 exaggeration 不够，也可能是因为缺少稳定参照物。
+
+没有清晰的海岸线、国界线和地表分层时，人眼很难判断：
+
+- 山脉是不是在应该高的地方高
+- terrain 是否真的贴在正确的大陆位置上
+- 地球纹理、本初子午线、terrain 采样之间是否存在偏移
+
+这里要明确区分两件事：
+
+- 国界线不会修好错误的 terrain
+- 但海岸线 / 国界线会让我们更容易判断 terrain 有没有贴准
+
+所以在继续盲调 terrain 参数之前，建议先插入一个“校准参照层”阶段。
+
+### Recommended order for the calibration layer
+
+1. 海岸线
+2. 国界线
+3. 再继续调 terrain
+
+原因：
+
+- 海岸线比国界线更基础，也更接近真实地表边界
+- 判断 terrain 是否贴准，最重要的是大陆边缘和山脉/海岸关系
+- 国界线更多是政治边界，只能作为辅助参照
+
+如果只加国界线，不加海岸线，效果仍然可能会怪，因为：
+
+- 很多国界线本来就是人为直线
+- 它们并不总是跟真实地形走
+
+### Suggested layer order during debugging
+
+建议调试期临时把地球层次明确成：
+
+1. base earth texture
+2. coastline / borders overlay
+3. terrain relief
+4. cables / landing points / bgp / satellites
+
+这样会比现在更容易判断：
+
+- 山脉是否位于正确区域
+- terrain 是否和地表对齐
+- 国界/海岸是否漂移
+
+### Suggested data source for the calibration overlay
+
+优先用 `Natural Earth` 的轻量全球矢量数据：
+
+- 海岸线（coastline）
+- Admin 0 国界线（country borders）
+
+优点：
+
+- 全球一致
+- 轻量
+- 很适合当前 Three.js globe 做 overlay
+
+### Recommended execution path
+
+#### Phase A — Add reference overlays
+
+先加两层可开关的参考线：
+
+- 海岸线
+- 国界线
+
+这两层的目标不是最终美术表现，而是调试 / 校准。
+
+#### Phase B — Recalibrate terrain against coastline
+
+有了海岸线以后，再重新看 terrain：
+
+- terrain 是否和大陆边缘错位
+- 地球纹理、本初子午线、terrain 采样之间是否有固定偏移
+
+#### Phase C — Decide whether to keep the current terrain path
+
+这时再决定后面的路线：
+
+- 如果发现真实高程整体是对的，只是缺少 shading / readability  
+  继续保留当前 DEM + terrain overlay 路线
+- 如果发现整球采样投影、本初子午线或 overlay 关系本身就很别扭  
+  再考虑重做 terrain pipeline
+
+### Practical recommendation
+
+当前阶段不建议“从头开始重做 terrain”。
+
+更稳的策略是：
+
+- 暂停继续盲调 terrain 参数
+- 先补海岸线 / 国界线作为校准参照层
+- 再基于参照层判断 terrain 是“参数没调好”，还是“整条实现路径有偏移”
+
+## Recommended Geometry Model
+
+### First usable model
+
+保留一层独立 terrain sphere：
+
+- base earth sphere：贴纹理、昼夜、海洋
+- terrain sphere：略高于地球半径，真实高程位移
+
+建议：
+
+- `terrainBaseRadius = CONFIG.earthRadius + 0.2`
+- 高度缩放使用真实米制换算，再乘一个可调 exaggeration
+
+示例关系：
+
+- `heightWorld = (elevationMeters / 6371000) * CONFIG.earthRadius * exaggeration`
+
+建议第一阶段 `exaggeration = 1.3 ~ 1.8`
+
+因为完全真实比例在全球球体上会太平，看不出来。
+
+## Tile Decoding Plan
+
+### Terrarium decode
+
+对于每个高程 tile 像素：
+
+```text
+heightMeters = (R * 256 + G + B / 256) - 32768
+```
+
+### Sampling path
+
+对于 terrain mesh 上每个顶点：
+
+1. 将顶点方向转成经纬度
+2. 将经纬度映射到 Web Mercator tile 坐标
+3. 找到对应的 tile 和像素
+4. 解码高程
+5. 将顶点沿法线方向抬升
+
+### Needed helpers
+
+建议新增：
+
+- `latLonToTileXY(lat, lon, z)`
+- `tilePixelFromLatLon(lat, lon, z, tileSize)`
+- `decodeTerrariumHeight(r, g, b)`
+
+## Caching Strategy
+
+为了不让地形开关每次重开都重新抓全量 tile：
+
+- terrain tile 按 `z/x/y` 存到内存缓存
+- terrain mesh 结果也缓存一份
+- 当用户关闭/开启 terrain：
+  - 直接复用已有位移结果
+
+建议：
+
+- `Map<string, Float32Array | ImageBitmap>`
+
+## Material Strategy
+
+第一阶段不要复杂化。
+
+建议 terrain material：
+
+- 半透明低饱和地形色
+- 比 base earth 稍亮或稍偏冷
+- 保留当前 HUD 风格下的可读性
+
+第一阶段不需要：
+
+- 真实土地覆被纹理
+- 独立卫星影像贴 terrain
+
+因为那会和现有地球纹理、云层、昼夜 shader 打架。
+
+## Integration Points
+
+### Files to change
+
+- [earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js)
+  - 重写 `createTerrain()`
+  - 删除 simplex noise 占位逻辑
+- [main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js)
+  - 初始化 terrain 数据加载
+  - 控制 terrain readiness / loading message
+- [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js)
+  - `toggleTerrain` 逻辑保持，但应能区分：
+    - mesh 已就绪
+    - 正在加载
+- [constants.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/constants.js)
+  - 新增 `TERRAIN_CONFIG`
+- 新文件：
+  - `frontend/public/earth/js/terrain.js`
+
+### Suggested new config
+
+建议新增：
+
+```js
+export const TERRAIN_CONFIG = {
+  enabled: true,
+  tileSize: 256,
+  baseZoom: 4,
+  baseRadiusOffset: 0.2,
+  exaggeration: 1.5,
+  opacity: 0.55,
+  color: 0x6c876f,
+  maxConcurrentRequests: 8,
+  cacheEnabled: true,
+};
+```
+
+## Loading UX
+
+地形第一次开启时，不能像现在一样瞬时切换。
+
+建议：
+
+- 如果地形数据尚未准备：
+  - 顶部状态条显示：`正在加载真实地形数据...`
+- 完成后：
+  - `真实地形已就绪`
+
+如果加载失败：
+
+- 保留 base earth
+- 显示轻量错误提示
+- 不要让 terrain 开关卡死在“开”状态
+
+## Risks
+
+### 1. Global tile count too high
+
+即使 `z=5` 全球 tile 数也不少。
+
+缓解：
+
+- 第一阶段限定低 zoom
+- 并发上限
+- 缓存
+
+### 2. Mesh resolution too low
+
+如果球面分段太低，山脉会被抹平。
+
+缓解：
+
+- 第一阶段先选一个中等分辨率
+- 用 exaggeration 保证可见性
+
+### 3. Existing overlays may z-fight with terrain
+
+海缆、登陆点、BGP、卫星相关对象都假设地球半径固定。
+
+缓解：
+
+- terrain sphere 单独作为 overlay
+- overlay 保持略低或略高的固定 offset
+- 必要时局部调整 landing point / cable altitude offset
+
+### 4. Mercator sampling distortion near poles
+
+Web Mercator 在高纬会有失真。
+
+缓解：
+
+- 第一阶段接受
+- 后续若需要更严格极区质量，再上 geodetic reprojection pipeline
+
+## Acceptance Criteria
+
+第一阶段完成后，应满足：
+
+1. `地形 terrain` 开关开启时，地表起伏明显不再是随机噪声
+2. 喜马拉雅、安第斯、落基山、东非高原等全球大尺度地形可辨认
+3. 关闭/重新开启 terrain 不重复全量请求
+4. 不破坏：
+   - 海缆
+   - 卫星
+   - BGP
+   - 地球昼夜
+   - 天球层
+
+## Suggested Execution Order
+
+1. 引入 `TERRAIN_CONFIG`
+2. 新建 `terrain.js`
+3. 实现 Terrarium tile 请求与 decode
+4. 用低 zoom 全球 tile 构建真实 terrain sphere
+5. 接管 `toggleTerrain()`
+6. 调整 terrain material 和高度 exaggeration
+7. 做缓存
+8. 再考虑第二阶段局部高分 refinement

+
+## Recommendation Summary
+
+如果现在就要开始做，我建议直接按这条路线开工：
+
+- 第一阶段接入 Terrarium 全球高程 tile
+- 替换掉当前 simplex 假地形
+- 先做一层真实可见的全球 terrain overlay
+- 等第一阶段稳定，再做视角高分 refinement
+
+这是对当前项目风险最低、最贴合现有 Earth 架构的一条路。
