Geometry defines the shape of 3D objects via vertices, faces, normals, and UVs stored in buffer attributes.

| position | 3 | Vertex positions (x, y, z) | | normal | 3 | Surface normals for lighting | | uv | 2 | Texture coordinates (u, v) | | color | 3 | Per-vertex colors (r, g, b) | | index | 1 | Triangle indices (optional) |

Render thousands of identical meshes with different transforms in a single draw call:

BufferGeometry 創建、內置幾何體、具有緩衝區屬性的自定義幾何體、用於渲染數千個對象的實例網格以及幾何體操作。在創建自定義形狀、通過實例優化或直接使用頂點數據時使用。 來源：bbeierle12/skill-mcp-claude。
