| triangles | A list of vertex indices to populate. Any existing items in the list are replaced. |
| submesh | The sub-mesh index. See subMeshCount. |
| applyBaseVertex | True (default value) will apply base vertex offset to returned indices. |
Fetches the triangle list for the specified sub-mesh on this object.
Each integer in the returned triangle list is a vertex index, which is used as an offset into the Mesh's vertex arrays. See vertices and GetVertices. The triangle list contains a multiple of three indices, one for each corner in each triangle.
A sub-mesh represents a list of triangles that are rendered using a single Material. When the Mesh is used with a Renderer that has multiple materials, you should ensure that there is one sub-mesh per Material.
Call the method overload with a List<int> parameter if you control the life cycle of the index buffer and wish to avoid allocation of a new array with every access.
