Chopping with CGAL is 10 times faster in our upcoming release, CGAL 6.1.
Re-implemented from scratch, clipping/splitting now supports non-triangular faces and can handle self-intersecting inputs.

New in CGAL: Robust and fast self-intersection removal in triangle meshes!
Combining Boolean operations and snap rounding, we remove all self-intersections consistently, for example over all of Thingi10k.
Work to be presented at SGP in Bilbao this week.

New in CGAL: A new method for surface remeshing, with sharp feature preservation.
"ACVD Remeshing" is based on publications of Valette et al., and uses clusters of vertices, which are grown to minimize a particular energy until convergence.
