IDirect3DDevice9::SetVertexShader Method

Sets the vertex shader.

Syntax

HRESULT SetVertexShader(      

    IDirect3DVertexShader9* pShader
);

Parameters

pShader

[in] Vertex shader interface. For more information, see IDirect3DVertexShader9.

Return Value

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be D3DERR_INVALIDCALL.

Remarks

To set a fixed-function vertex shader (after having set a programmable vertex shader), call IDirect3DDevice9::SetVertexShader(NULL) to release the programmable shader, and then call IDirect3DDevice9::SetFVF with the fixed-function vertex format.
