IDirect3DDevice3::DrawPrimitiveStrided

The IDirect3DDevice3::DrawPrimitiveStrided method renders the specified array of strided vertices as a sequence of geometric primitives. For more information, see Strided Vertex Format.

HRESULT DrawPrimitiveStrided(
  D3DPRIMITIVETYPE dptPrimitiveType,  
  DWORD  dwVertexTypeDesc,            
  LPD3DDRAWPRIMITIVESTRIDEDDATA lpVertexArray,  
  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 describe the vertex format.
lpVertexArray
Array of D3DDRAWPRIMITIVESTRIDEDDATA structures that contains the vertices for this primitive.
dwVertexCount
Number of vertices in the array at lpVertexArray. The maximum number of vertices allowed is 65,535 (0xFFFF).
dwFlags
One or more of the following flags defining how the primitive is drawn:
D3DDP_DONOTCLIP
The application has already done the required clipping, so the system should not necessarily clip the primitives. (This flag is a hint; the system may clip the primitive even when this flag is specified, under some circumstances.)
D3DDP_DONOTLIGHT
Disables the Direct3D lighting engine. The system uses the diffuse and specular components at each vertex for shading when it rasterizes the set of primitives. If a diffuse or specular component is not specified, the system uses the default color for the missing component (0xFFFFFFFF for diffuse and 0x00000000 for specular).
D3DDP_DONOTUPDATEEXTENTS
Disables the updating of the screen rectangle affected by this rendering call. Using this flag can potentially help performance, but the extents returned by IDirect3DDevice3::GetClipStatus will not have been updated to account for the data rendered by this call.
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 may be one of the following values:

D3DERR_INVALIDRAMPTEXTURE
D3DERR_INVALIDPRIMITIVETYPE
D3DERR_INVALIDVERTEXTYPE
DDERR_INVALIDPARAMS
DDERR_WASSTILLDRAWING

Remarks

This method does not support transformed vertices. As a result, if you include the D3DFVF_XYZRHW vertex format descriptor in the dwVertexTypeDesc parameter, the method fails, returning D3DERR_INVALIDVERTEXTYPE.

This method was introduced with the IDirect3DDevice3 interface.
