threejs-geometries

When to use this skill

ALWAYS use this skill when the user mentions:

• Building or modifying BufferGeometry, attributes, index buffers, draw ranges
• Instancing via InstancedBufferAttribute / InstancedMesh geometry side (threejs-objects for mesh wrapper)
• Extruding Shape along paths, TubeGeometry, LatheGeometry, ExtrudeGeometry
• Text or decal addon geometries

IMPORTANT: geometries vs math

• threejs-geometries = GPU-ready triangle data.
• threejs-math = Box3, Sphere, Ray tests without mesh topology.

Trigger phrases include:

• "BufferGeometry", "BufferAttribute", "ExtrudeGeometry", "Shape", "Curve"
• "几何体", "缓冲几何", "挤出", "文字几何"
