CesiumJS 3D Tiles loads Cesium3DTileset content, Mapbox Vector Tiles, point clouds, voxels, and related 3D data. Use it to style, pick, clip, and query tiled spatial features in CesiumJS.

CesiumJS Camera & Navigation controls camera placement, flyTo animations, entity tracking, and screen-to-world coordinate workflows in CesiumJS. Use it when positioning the camera or constraining user navigation.

CesiumJS Core Utilities provides Resource, Color, Event, Request, and helper APIs for fetching data, managing HTTP requests, working with colors, and handling events. Use it when building or debugging CesiumJS code that needs networking or core utility functions.

CesiumJS Custom Shader writes vertex and fragment GLSL for Model, Cesium3DTileset, and VoxelPrimitive rendering. Use it to read feature metadata, displace vertices, or control material shading at runtime.

CesiumJS Entities lets you work with the high-level Entity API for points, labels, models, polygons, polylines, and other graphics. Use it when loading GeoJSON, KML, CZML, or GPX into EntityCollection-based scenes.

CesiumJS Imagery Layers covers imagery providers, layer stacking, and layer display settings for CesiumJS maps. Use it when adding, swapping, or comparing base map sources like WMS, WMTS, Bing, OpenStreetMap, ArcGIS, or Mapbox.

CesiumJS Interaction handles mouse, touch, and modifier-key input on the Cesium canvas. Use it to pick entities or 3D Tiles, read world positions, and build click, hover, drag, and shortcut behaviors.

CesiumJS Materials And Shaders covers Fabric materials, CustomShader hooks, image-based lighting, and screen-space post-processing. Use it when styling primitives and models or adding effects like bloom, depth of field, ambient occlusion, FXAA, and tonemapping.

CesiumJS Models and Particles loads glTF/GLB models with animations, node transforms, edge display, and particle effects. Use it for compressed or CAD-style assets, model playback, and geospatial particle systems.

CesiumJS Primitives & Geometry covers low-level rendering with Primitive, GeometryInstance, appearances, and primitive collections. Use it for performance-critical static geometry, batched draw calls, GeoJSON without entities, and custom shapes.

CesiumJS Skills Orientation provides a map of available CesiumJS domain skills and when they apply. Use it when starting a CesiumJS conversation to route questions to the right skill, with passive activation by description matching.

CesiumJS Spatial Math covers Cartesian, cartographic, ellipsoid, matrix, and transform utilities for converting coordinates and building model matrices. Use it for globe positions, surface projections, and spatial intersection checks.

CesiumJS Terrain And Globe Environment covers terrain providers, terrain height sampling, globe rendering, atmosphere, sky, lighting, shadows, and translucency. Use it when configuring terrain, querying heights, or tuning scene appearance.

CesiumJS Time And Animation covers Clock, JulianDate, TimeInterval, and the Property system for time-dynamic entities. Use it for simulation timing, interpolated positions, sampled data, and callback-driven attributes or path materials.

CesiumJS Viewer Setup helps initialize a CesiumJS globe with Viewer or CesiumWidget, Ion tokens, terrain, imagery, widgets, and scene options. Use it when bootstrapping an app or configuring 2D/3D view modes and platform services.
