cesiumjs

cesiumjs is a skill for Claude Code, Codex from znlgis/opengis-skills. It costs 52 tokens per session (2,569 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 0 findings 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

安装

npm install cesium
<link href="https://cdn.jsdelivr.net/npm/cesium/Build/Cesium/Widgets/widgets.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/cesium/Build/Cesium/Cesium.js"></script>

Vite 集成

import { defineConfig } from 'vite';
import cesium from 'vite-plugin-cesium';
export default defineConfig({ plugins: [cesium()] });

Webpack 集成

需将 node_modules/cesium/Build/Cesium/{Workers,Assets,Widgets} 拷贝到输出目录,并设置 window.CESIUM_BASE_URL


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)
  });
</script>

核心概念

概念 说明
Viewer 顶层容器
Scene 渲染场景,含 globe/camera/primitives
Entity 高层数据对象,时序、属性、可视化封装
DataSource Entity 集合(CZML/GeoJSON/KML)
Primitive 低层渲染单元,性能最优
Cesium3DTileset 3D Tiles 数据集

影像与地形

viewer.imageryLayers.addImageryProvider(new Cesium.UrlTemplateImageryProvider({
  url: 'https://webst02.is.autonavi.com/appmaptile?style=6&x={x}&y={y}&z={z}'
}));

viewer.terrainProvider = await Cesium.createWorldTerrainAsync({
  requestVertexNormals: true,
  requestWaterMask: true
});

What this file has done since we first saw it

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.
