libzfp - Runtime library for zfp
- Description:
This is zfp, an open source C/C++ library for compressed numerical
arrays that support high throughput read and write random access. zfp
was written by Peter Lindstrom at Lawrence Livermore National
Laboratory, and is loosely based on the algorithm described in the
following paper:
Peter Lindstrom
"Fixed-Rate Compressed Floating-Point Arrays"
IEEE Transactions on Visualization and Computer Graphics,
20(12):2674-2683, December 2014
doi:10.1109/TVCG.2014.2346458
zfp was originally designed for floating-point data only, but has been
extended to also support integer data, and could for instance be used
to compress images and quantized volumetric data. To achieve high
compression ratios, zfp uses lossy but optionally error-bounded
compression. Although bit-for-bit lossless compression of
floating-point data is not always possible, zfp is usually accurate to
within machine epsilon in near-lossless mode.
zfp works best for 2D and 3D arrays that exhibit spatial coherence,
such as smooth fields from physics simulations, images, regularly
sampled terrain surfaces, etc. Although zfp also provides a 1D array
class that can be used for 1D signals such as audio, or even
unstructured floating-point streams, the compression scheme has not
been well optimized for this use case, and rate and quality may not be
competitive with floating-point compressors designed specifically for
1D streams.
This package contains the runtime library for zfp.
