ID3DXEffectStateManager::SetTransform

A callback function that must be implemented by a user to set a transform.

HRESULT SetTransform(
  D3DTRANSFORMSTATETYPE State,
  CONST D3DMATRIX* pMatrix
);

Parameters

State

[in] The type of transform to apply the matrix to. See D3DTRANSFORMSTATETYPE.

pMatrix

[in] A transformation matrix. See D3DMATRIX.

Return Values

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::SetTransform) will fail.
