D3DDDIARG_DRAWINDEXEDPRIMITIVE structure (d3dumddi.h)

The D3DDDIARG_DRAWINDEXEDPRIMITIVE structure describes an indexed primitive to draw.

Syntax

typedef struct _D3DDDIARG_DRAWINDEXEDPRIMITIVE {
  [in] D3DPRIMITIVETYPE PrimitiveType;
  [in] INT              BaseVertexIndex;
  [in] UINT             MinIndex;
  [in] UINT             NumVertices;
  [in] UINT             StartIndex;
  [in] UINT             PrimitiveCount;
} D3DDDIARG_DRAWINDEXEDPRIMITIVE;

Members

[in] PrimitiveType

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.

[in] BaseVertexIndex

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.

[in] MinIndex

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.

[in] NumVertices

The number of vertices in a range that are potentially accessed by the primitives to be drawn and, therefore, which vertices should be processed.

[in] StartIndex

The first index in the index buffer from which indices are read to draw the primitives.

[in] PrimitiveCount

The number of triangles, lines, or points to draw for the given primitive.

Remarks

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.
