The D3DDDIARG_DRAWINDEXEDPRIMITIVE structure describes an indexed primitive to draw.
PrimitiveType [in]A D3DPRIMITIVETYPE-typed value that indicates the type of primitive to draw. This member can be one of the following values: D3DPT_POINTLIST, D3DPT_LINELIST, D3DPT_LINESTRIP, D3DPT_TRIANGLELIST, D3DPT_TRIANGLESTRIP, or D3DPT_TRIANGLEFAN. For more information about D3DPRIMITIVETYPE, see the Microsoft Windows SDK documentation.
BaseVertexIndex [in]The number that should be added to each index that is referenced by the various primitives to determine the actual index of the vertex elements in each vertex stream.
MinIndex [in]The minimum index of a range of vertices that are potentially accessed by the primitives to be drawn and, therefore, which vertices should be processed.
NumVertices [in]The number of vertices in a range that are potentially accessed by the primitives to be drawn and, therefore, which vertices should be processed.
StartIndex [in]The first index in the index buffer from which indices are read to draw the primitives.
PrimitiveCount [in]The number of triangles, lines, or points to draw for the given primitive.
The Microsoft Direct3D runtime does not transform the index data before passing a pointer to the description of the index data in the pData parameter in a call to the user-mode display driver's DrawIndexedPrimitive function.
