This was asked on StackOverflow a while ago, but the answer no longer works since it relies on the now deprecated THREE.Geometry object. A new answer was added in August of this year, … Web来自BufferGeometry的文档： index (itemSize: 3) Allows for vertices to be re-used across multiple triangles; this is called using"indexed triangles," and works much the same as it does in Geometry: each triangle is associated with the index of three vertices. This attribute therefore stores the index of each vertex for each triangular face.
