Parameters
pState
Pointer to the ZFP decompression structure.
pDst
Pointer to the value at the coordinates (0, 0, 0) of the 3D destination buffer.
dstStep
Row step in bytes.
dstPlaneStep
Plane step in bytes.
Description
This function decodes a 4x4x4 block of 3D floating point data. The source data pointer is initialized by calling
DecodeZfpInit
and is updated automatically.
The function arranges the decompressed 3D data in the destination buffer in such a way that for any set of coordinates (x, y, z) within the 4x4x4 block,
pXYZ = (float *)((char *)pDst + x + y * dstStep + z * dstPlaneStep)
is a pointer to the value at (x, y, z).
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if any of the pointers is
NULL
.
ippStsContexMatchErr
Indicates an error if the ZFP decompression structure data is invalid.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
