Transforms animations in an animation set into a compressed format and returns a pointer to the buffer that stores the compressed data.
HRESULT Compress( [in] DWORD Flags, [in] FLOAT Lossiness, [in] LPD3DXFRAME pHierarchy, [out] LPD3DXBUFFER *ppCompressedData );
One of the D3DXCOMPRESSION_FLAGS values that define the compression mode used for storing compressed animation set data. D3DXCOMPRESS_DEFAULT is the only value currently supported.
Desired compression loss ratio, in the range from 0 to 1.
Pointer to a D3DXFRAME transformation frame hierarchy. Can be NULL.
Address of a pointer to the ID3DXBuffer compressed animation set.
If the method succeeds, the return value is S_OK. If the method fails, the return value can be one of the following values: D3DERR_INVALIDCALL, E_OUTOFMEMORY.
