Three.js Animation

Three.js animation - keyframe animation, skeletal animation, morph targets, animation mixing. Use when animating objects, playing GLTF animations, creating procedural motion, or blending animations.

When to Use

  • You need to animate objects, rigs, morph targets, or imported GLTF animations in Three.js.
  • The task involves mixers, clips, keyframes, procedural motion, or animation blending.
  • You are building motion behavior in a Three.js scene rather than just static rendering.

Core Workflow

  1. Confirm the request matches this skill's trigger, scope, and risk profile.
  2. Use the topic map to identify the relevant pattern, checklist, or example before writing detailed guidance or code.
  3. Load references/full-guidance.md when implementation details, examples, anti-patterns, validation checks, or edge cases are needed.
  4. Apply only the relevant guidance instead of loading or repeating the entire reference by default.
  5. Verify the result against any validation checks, limitations, security notes, or platform constraints in the reference.

Reference Map

  • references/full-guidance.md preserves the complete original guidance, including examples and detailed edge cases.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Progressive Loading

Keep this SKILL.md as the compact routing and workflow entrypoint. Load the reference file only when the user task requires the deeper implementation material.
