|Microsoft DirectX 9.0|
Both indexed and nonindexed drawing methods are supported by Microsoft?Direct3D? The indexed methods use a single set of indices for all vertex components. Vertex data is presented to the Direct3D application programming interface (API) in vertex buffers, and index data for the indexed drawing methods is presented in index buffers. For more information, see the following reference topics.
These methods draw primitives from the current set of data input streams. For details on setting the current index array to an index buffer, see the IDirect3DDevice9::SetIndices method.
