IDirect3DDevice7::DrawPrimitive

The IDirect3DDevice7::DrawPrimitive method renders the specified array of vertices as a sequence of geometric primitives of the specified type.

HRESULT DrawPrimitive(
  D3DPRIMITIVETYPE dptPrimitiveType,  
  DWORD  dwVertexTypeDesc,            
  LPVOID lpvVertices,                 
  DWORD  dwVertexCount,               
  DWORD  dwFlags                      
);

Parameters

dptPrimitiveType

Type of primitive to be rendered by this command. This must be one of the members of the D3DPRIMITIVETYPE enumerated type.

dwVertexTypeDesc

A combination of flexible vertex format flags that describes the vertex format used for this set of primitives.

lpvVertices

Pointer to the array of vertices to be used in the primitive sequence.

dwVertexCount

The number of vertices in the array. The maximum number of vertices allowed is D3DMAXNUMVERTICES (0xFFFF).

dwFlags

Zero to render the primitive without waiting, or the following flag:

D3DDP_WAIT

Causes the method to wait until the polygons have been rendered before it returns, instead of returning as soon as the polygons have been sent to the card. (On scene-capture cards, the method returns as soon as the card responds.) This flag is typically used for debugging. Applications should not attempt to use this flag to ensure that a scene is up to date before continuing.

Return Values

If the method succeeds, the return value is DD_OK.

If the method fails, the return value can be one of the following values:

Remarks

Be sure that the vertices being rendered match the vertex format that you specify. For performance reasons, Direct3D does not attempt to verify that vertex size and stride match the provided flexible vertex format. If a mismatch occurs, a memory fault is likely to result.

This method, unlike its predecessor in previous interfaces, does not accept the D3DDP_DONOTCLIP, D3DDP_DONOTLIGHT, and D3DDP_DONOTUPDATEEXTENTS flags in the dwFlags parameter. The functionality offered by these flags is now available through the D3DRENDERSTATE_CLIPPING, D3DRENDERSTATE_LIGHTING, and D3DRENDERSTATE_EXTENTS render states.
