python script to run InverseCSG on an example part from OpenLSTO based on the run_tests script that ships with InverseCSG

topopt2CSG.py

import os
import sys

# Usage: python3 topopt2CSG.py <build_dir> <test_name>
# Example:
# python3 topopt2CSG.py ../build openlsto 
#

if len(sys.argv) < 3:
  print('Error: please specify the test case name.')
  sys.exit(-1)

build_dir = sys.argv[1]
test_name = sys.argv[2]

if test_name == 'openlsto':
  os.system('python3 ../inverse_csg/main.py --builddir %s --outdir ../openlsto --mesh ../openlsto/mystlfile-openscad-import.off --eps 0.1 --surfacedensity 100 --volumedensity 10' % build_dir)
else:
  print('Unknown test case: %s' % test_name)
  sys.exit(-1)
