IDirect3DDevice9::SetVertexShader

Sets the vertex shader.

HRESULT SetVertexShader(
  IDirect3DVertexShader9* pShader
);

Parameters

pShader

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

Return Values

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.

Requirements

Header: Declared in D3d9.h.
