A callback function that must be implemented by a user to set a texture.
HRESULT SetTexture( [in] DWORD Stage, [in] LPDIRECT3DBASETEXTURE9 pTexture );
A pointer to the texture object. This can be any of the Direct3D texture types (cube, volume, etc.). See IDirect3DBaseTexture9.
The user-implemented method should return S_OK. If the callback fails when setting the device state, either of the following will occur:
- The effect will fail during ID3DXEffect::BeginPass.
- The dynamic effect state call (such as IDirect3DDevice9::SetTexture) will fail.
