  • Article

Sets the stream source frequency divider value. This may be used to draw several instances of geometry.

Syntax

HRESULT SetStreamSourceFreq(
  UINT StreamNumber,
  UINT Divider
);

Parameters

StreamNumber

Type: [in] UINT

Stream source number.

Divider

Type: [in] UINT

This parameter may have two different values. See remarks.

Return value

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).
