threejs-loaders covers gltf, obj, fbx, and environment map loading with progress tracking, error recovery via retry/fallback, and async patterns for parallel asset orchestration.

threejs-shaders covers custom glsl shader authoring via shadermaterial and rawshadermaterial, uniform management, six reusable shader patterns (displacement, fresnel, rim lighting, dissolve), and material injection via onbeforecompile for extending built-in materials.

threejs-geometry covers built-in shapes, custom buffer geometry construction, instanced rendering for many objects, and utilities for geometry manipulation. oriented toward 3d scene construction rather than procedural generation or optimization.

threejs-interaction provides basic setup patterns for raycasting, orbit controls, and mouse coordinate normalization. covers click detection scaffolding but lacks implementation completeness and error handling strategy.

threejs-postprocessing covers effect composer setup and basic bloom pass configuration. lacks depth on dof, screen effects, color grading, and practical integration patterns.

threejs-animation covers basic procedural animation patterns using three.js clock and transform updates, but lacks depth on skeletal animation, morph targets, and gltf playback mentioned in the description.

threejs-textures covers basic texture loading and material assignment in three.js, but lacks depth on uv mapping, cubemaps, hdr environments, and texture optimization mentioned in the description.

threejs-materials provides incomplete guidance on material instantiation and pbr properties, but lacks actionable procedure, failure modes, and concrete workflow coverage.

Three.js lighting - light types, shadows, environment lighting. Use when adding lights, configuring shadows, setting up IBL, or optimizing lighting performance.

Three.js scene setup, cameras, renderer, Object3D hierarchy, coordinate systems. Use when setting up 3D scenes, creating cameras, configuring renderers,…
