ID3DXPRTCompBuffer::ExtractBasis method

Extracts the mean and principal component analysis (PCA) basis vectors for a given cluster from an ID3DXPRTCompBuffer compressed data buffer.

Syntax

HRESULT ExtractBasis(
  [in]      UINT  Cluster,
  [in, out] FLOAT *pClusterBasis
);

Parameters

Cluster [in]

Type: UINT

Cluster for which the basis will be extracted.

pClusterBasis [in, out]

Type: FLOAT*

Pointer to an array of basis vector data for Cluster. The size of the FLOAT data stored will be: (1 + Number of PCA vectors per cluster) * (Number of coefficients) * (Number of color channels)

Return value

Type: HRESULT

If the method succeeds, the return value is S_OK. If the method fails, the following value will be returned.
