ID3DXPRTCompBuffer::ExtractToMesh method
Extracts the per-sample principal component analysis (PCA) projection coefficients from an ID3DXPRTCompBuffer compressed data buffer and adds the data to an ID3DXMesh object.
HRESULT ExtractToMesh(
[in] UINT NumPCA,
[in] D3DDECLUSAGE Usage,
[in] UINT UsageIndexStart,
[in] LPD3DXMESH pScene
);
-
NumPCA [in]
-
Type: UINT
Number of PCA coefficients to extract from the buffer.
-
Usage [in]
-
Type: D3DDECLUSAGE
Vertex usage descriptions of the mesh. See D3DDECLUSAGE.
-
UsageIndexStart [in]
-
Type: UINT
Starting index for PCA coefficients to be stored in the mesh.
-
pScene [in]
-
Type: LPD3DXMESH
Pointer to an ID3DXMesh mesh object that will store PCA coefficients.
Type: HRESULT
If the method succeeds, the return value is S_OK. If the method fails, the return value can be one of the following: D3DERR_INVALIDCALL, E_OUTOFMEMORY.
