Index buffers are memory resources used to hold indices. They are similar to surfaces and vertex buffers. The use of index buffers enables Microsoft Direct3D to avoid unnecessary data copying and to place the buffer in the optimal memory type for the expected usage.
To use index buffers, create an index buffer, lock it, fill it with indices, unlock it, pass it to Device.Indices, set up the vertices, set up the vertex shader, and call Device.DrawIndexedPrimitives for rendering.
The Caps.MaxVertexIndex member indicates the types of index buffers that are valid for rendering.
Exceptions
InvalidCallException The method call is invalid. For example, a method's parameter might contain an invalid value. InvalidDataException The data is invalid. OutOfVideoMemoryException Direct3D does not have enough display memory to perform the operation. OutOfMemoryException Direct3D could not allocate sufficient memory to complete the call.
