cpSZ

Critical point preserving for vector fields

Installation

sh build_script.sh
Dependancies: ZSTD

Run compression

./build/bin/sz_compress_cp_preserve_2d_test data/uf.dat data/vf.dat 2400 3600 0.1
Decompressed data files are data/uf.dat.out and data/vf.dat.out

Evaluation

./external/ftk/build/bin/ex_cp_2d_bilinear 3600 2400 ./data/uf.dat ./data/vf.dat test
To test 2D linear vector fields, re-build the executables and re-run the compression after changing the corresponding lines (comment line 23 and uncomment line 24) and then evaluate with the following command:
./external/ftk/build/bin/ex_cp_2d 3600 2400 ./data/uf.dat ./data/vf.dat test
