threejs-loaders

Asset loading for 3D models, textures, HDR environments, and progress tracking in Three.js. Coordinate multiple loaders and track progress. For environment maps and skyboxes. Generate prefiltered environment maps for PBR. The most common 3D format for web. - Supports multiple formats: GLTF/GLB (primary), OBJ+MTL, FBX, STL, PLY, and HDR/EXR environment maps with optional DRACO geometry and KTX2 texture compression - LoadingManager coordinates multiple loaders with progress callbacks, onLoad/onError handlers, and unified asset tracking across the scene - Texture configuration covers wrapping modes, filtering, anisotropic sharpening, color space management, and repeat/offset/rotation transforms - Async/Promise patterns with helper functions for loading single or multiple assets in parallel, plus custom caching and asset manager implementations - Error handling includes retry logic, fallback URLs, timeout protection, and graceful degradation with placeholder meshes during load - Use compressed formats : DRACO for geometry, KTX2/Basis for textures - Load progressively : Show placeholders while loading - Lazy load : Only load what's needed - Use CDN : Faster asset delivery - Enable cache : THREE.Cache.enabled = true - threejs-textures - Texture configuration - threejs-animation - Playing loaded animations - threejs-materials - Material from loaded models
