ID3DXEffectStateManager::SetTransform method

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

Syntax

HRESULT SetTransform(
  [in]       D3DTRANSFORMSTATETYPE State,
  [in] const D3DMATRIX             *pMatrix
);

Parameters

State [in]

Type: D3DTRANSFORMSTATETYPE

The type of transform to apply the matrix to. See D3DTRANSFORMSTATETYPE.

pMatrix [in]

Type: const D3DMATRIX*

A transformation matrix. See D3DMATRIX.

Return value

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.
