description: Route ambitious Three.js graphics work to the smallest expert skill set. Use for new visual experiences, graphics rewrites, reference matching, or requests spanning geometry, materials, atmosphere, shadows, temporal effects, and final image treatment.

Three.js Visual Skill Router

Treat the model's Three.js knowledge and official documentation as prerequisites. Load only the expertise that changes the visual result.

This pack goes beyond procedural guidance: its working examples and supporting assets contain much of its practical implementation value. When they are relevant, give them particular attention.

Execution order

For a new procedural scene:

1. Define a visual contract: subject, scale, camera distance, motion, and target frame budget. 2. Load `$threejs-camera-direction` when framing, lens, camera frame, or mode transitions affect the
