IDirect3DDevice9::SetStreamSourceFreq method
Sets the stream source frequency divider value. This may be used to draw several instances of geometry.
Syntax
HRESULT SetStreamSourceFreq( [in] UINT StreamNumber, [in] UINT FrequencyParameter );
Parameters
- StreamNumber [in]
-
Type: UINT
Stream source number.
- FrequencyParameter [in]
-
Type: UINT
This parameter may have two different values. See remarks.
Return value
Type: HRESULT
If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be D3DERR_INVALIDCALL.
Remarks
There are two constants defined in d3d9types.h that are designed to use with SetStreamSourceFreq: D3DSTREAMSOURCE_INDEXEDDATA and D3DSTREAMSOURCE_INSTANCEDATA. To see how to use the constants, see Efficiently Drawing Multiple Instances of Geometry (Direct3D 9).
