cesiumjs

cesiumjs is a skill for Claude Code, Codex from znlgis/opengis-skills. It costs 93 tokens per session (3,794 once invoked), scanned A, original, MIT.

A JavaScript library for showing interactive three-dimensional globes and geographic data in a web browser. It supports Earth imagery and terrain, streamed 3D city or building data, 3D models, and time-based visualisations.

In plain words
What is it for?
Use it to build virtual globes, display terrain and satellite imagery, stream large 3D Tiles datasets, show glTF or GLB models, and animate data over time. It also supports analyses such as visibility, cross-sections, buffers, clipping, and lighting.
Why use it?
It provides the globe, map rendering, and geographic display tools needed for browser-based Earth applications. This avoids building those visualisation foundations yourself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cesiumjs scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

概述

CesiumJS 提供:

  • 三维全球:WGS84 椭球体、地形(Quantized-Mesh)、卫星影像
  • 3D Tiles:海量三维流式(倾斜摄影、BIM、点云、城市模型)
  • glTF / GLB 模型:标准 PBR 渲染
  • CZML / Entity API:高层声明式数据模型,时序动画
  • Primitive API:底层高性能 API
  • 可视化分析:通视/剖面/缓冲/裁剪/视频投影/光影

安装

方式一:npm

npm install cesium
npm ls cesium            # 验证:应显示 [email protected]
import { defineConfig } from 'vite';
import cesium from 'vite-plugin-cesium';

export default defineConfig({ plugins: [cesium()] });

方式二:CDN

<link href="https://cdn.jsdelivr.net/npm/[email protected]/Build/Cesium/Widgets/widgets.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/[email protected]/Build/Cesium/Cesium.js"></script>
# 验证 CDN 版本可达
curl.exe -I https://cdn.jsdelivr.net/npm/[email protected]/Build/Cesium/Cesium.js   # 期望 200

打包器接入

  • Vite:用 vite-plugin-cesium,按上面的 vite.config.js 注册,插件负责拷贝静态资源
  • Webpack:将 node_modules/cesium/Build/Cesium/{Workers,Assets,Widgets} 拷到输出目录,并在入口最早处设置 window.CESIUM_BASE_URL

1.146 变更: 数学/几何/时间/工具类被拆分为新包 @cesium/core([email protected] 依赖 @cesium/core@^0.1.0)。从 cesium 主包导入的代码不受影响;直接按子路径引用 @cesium/engine 的代码需改从 @cesium/core 导入(旧导出计划在后续版本移除,1.146 仍可用)。


快速上手

<div id="cesiumContainer" style="width:100%;height:100vh"></div>
<script type="module">
  import * as Cesium from 'cesium';
  import 'cesium/Build/Cesium/Widgets/widgets.css';

  Cesium.Ion.defaultAccessToken = 'YOUR_ION_TOKEN';

  const viewer = new Cesium.Viewer('cesiumContainer', {
    terrainProvider: await Cesium.createWorldTerrainAsync(),
    timeline: false, animation: false
  });

  viewer.camera.flyTo({
    destination: Cesium.Cartesian3.fromDegrees(116.397, 39.908, 5000)
  });

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
