Threejs Animation

Handles the full Three.js animation pipeline from basic procedural motion to complex skeletal rigs with blend trees. Covers AnimationMixer setup, keyframe track creation, GLTF animation loading, morph target blending, and multi-action crossfading. Most useful when you're moving beyond simple tweens and need proper character animation, facial expressions, or complex object choreography. The skeletal animation examples are solid for rigged characters, and the action blending patterns work well for game-style state machines. Documentation is thorough on the mixing and weighting mechanics that usually trip people up.
