BUG - long runtime/seg fault #14
Description
Cgal clip seems to go into an infinite loop when trying to clip a surface where the clipping surface is already co-aligned with an edge in the surface to be clipped. This often happens when a surface is clipped by the same surface twice.
Possible solutions
- Add a hash to prevent the same surface clipping a surface without remeshing
- Call the pmp::clip algorithm asynchronously and timeout if it takes longer than a specified time e.g. 1 minute
- Perform more geometry checks prior to clipping
- Change numerical precision
