IDirect3DDevice8::SetVertexShader
Sets the current vertex shader to a previously created vertex shader or to a flexible vertex format (FVF) fixed function shader.
HRESULT SetVertexShader( DWORD Handle );
Parameters
- Handle
- [in] Handle to a vertex shader, specifying the vertex shader to set. The value for this parameter can be the handle returned by IDirect3DDevice8::CreateVertexShader, or an FVF code. An FVF code is a combination of Flexible Vertex Format Flags.
Return Values
If the method succeeds, the return value is D3D_OK.
If the method fails, the return value can be D3DERR_INVALIDCALL.
Remarks
The effect of using an FVF code in place of the handle is to enable a fixed-function vertex shader, with an implicit declaration that matches the FVF code contents read from stream zero. Only stream zero is referenced when an FVF-specified shader is bound to the device.
Requirements
