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-lighting covers basic light type instantiation and scene attachment, but lacks procedural depth for shadows, ibl setup, performance tuning, or configuration workflows.

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-fundamentals provides minimal boilerplate for instantiating a three.js scene with camera and renderer, but lacks substantive guidance on configuration, hierarchy setup, or coordinate system usage claimed in the description.

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