make breve_bin -j 4

Thingi10k scripts

  • Download Thingi10k models without self intersection and manifold. (5172 results, and we provide the list in fullname_10k_good.txt) https://ten-thousand-models.appspot.com/results.html?q=with+not+self-intersection%2C+is+manifold
  • Use your favorite job scheduler to loop through the files. An example bash script is as follows.
binary=PATH_TO_BUILD/breve_bin
for i in {1..5172}
do
   ( let "fid = $i"
    filename=$(sed ${fid}'q;d' fullname_10k_good.txt)
    $binary -i $INPUT_DIR$filename -o $OUTPUT_DIR -l $LOG_DIR --loglevel 2 --serial shell --simplify-shell --init-thick 0.0001 --angle 0.001 --thick 0.05)
done
