ID3DX11FFT::InverseTransform method (d3dcsx.h)

Performs an inverse FFT.

Syntax

HRESULT InverseTransform(
  [in]      const ID3D11UnorderedAccessView *pInputBuffer,
  [in, out] ID3D11UnorderedAccessView       **ppOutputBuffer
);

Parameters

[in] pInputBuffer

Type: const ID3D11UnorderedAccessView*

Pointer to ID3D11UnorderedAccessView onto the input buffer.

[in, out] ppOutputBuffer

Type: ID3D11UnorderedAccessView**

Pointer to a ID3D11UnorderedAccessView pointer. If *ppOutput is NULL, then the computation will switch between temp buffers; in addition, the last buffer written to is stored at *ppOutput. Otherwise, *ppOutput is used as the output buffer (which might incur an extra copy).

Return value

Type: HRESULT

Returns one of the return codes described in the topic Direct3D 11 Return Codes.
