D3DHAL_DP2DRAWINDEXEDPRIMITIVE

  • Article

This structure is parsed from the command buffer by the D3dDrawPrimitives2 callback when the D3DHAL_DP2COMMAND structure's bCommand member is set to D3DDP2OP_DRAWINDEXEDPRIMITIVE, and is used to render a primitive using vertex indices.

typedef struct _D3DHAL_DP2DRAWINDEXEDPRIMITIVE {
  D3DPRIMITIVETYPE primType;
  DWORD BaseVertexIndex; 
  DWORD MinIndex; 
  DWORD NumVertices; 
  DWORD StartIndex; 
  DWORD PrimitiveCount;
} D3DHAL_DP2DRAWINDEXEDPRIMITIVE, *LPD3DHAL_DP2DRAWINDEXEDPRIMITIVE;

Members

  • primType
    Specifies the type of primitive to draw (one of D3DPT_POINTLIST, D3DPT_LINELIST, D3DPT_LINESTRIP, D3DPT_TRIANGLELIST, D3DPT_TRIANGLESTRIP or D3DPT_TRIANGLEFAN).
  • BaseVertexIndex
    Specifies the amount that should be added to each index referenced by the various primitives to determine the actual index of the vertex elements in each vertex stream.
  • MinIndex
    Specifies 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
    Specifies 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
    Specifies the first index in the index buffer from which indices are read to draw the primitives.
  • PrimitiveCount
    Specifies the number of triangles, lines or points to draw for the given primitive.

Remarks

The vertex data can be untransformed (if the hardware supports hardware vertex processing) or transformed if the application supplied data in that form to the run time.

As with vertices, the actual indices to use are not passed with the token data, but rather should be read from the currently selected index buffer.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: D3dhal.h.
