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 创建、内置几何体、具有缓冲区属性的自定义几何体、用于渲染数千个对象的实例网格以及几何体操作。在创建自定义形状、通过实例优化或直接使用顶点数据时使用。 来源：bbeierle12/skill-mcp-claude。
