An AMAPstudio .ops scene can be converted into a .obj file with Simeo > Edito in interactive mode. This is also possible with the following script in a terminal. This script will load the .ops in read only mode (no file copies) and will make the job faster.

The result file(s) will be written in the same directory than the ops file.

These commands must be called from the AMAPstudio install dir.

// Example under Linux
sh simeo.sh -p script jeeb.simeo.module.simeoeditor.scripts.Ops2Obj data/ops/littleScene.ops

// Example under Windows
simeo -p script jeeb.simeo.module.simeoeditor.scripts.Ops2Obj data/ops/littleScene.ops

coligny@marvin-13:~/workspace/amapstudio$ sh simeo.sh -p script jeeb.simeo.module.simeoeditor.scripts.Ops2Obj data/ops/littleScene.ops
-> OS/JVM/memory: linux/64/8000m
Default locale is: en 
Simeo root directory: /home/coligny/workspace/amapstudio
