There is a remeshing tool in the CGAL 3.6 demo app Polyhedron_3. It is not
very stable and crashes often. It seems that this is a problem of the
surface mesh generator.

remesh with:
angle=25
sizing=10.8584
approx=1.08584
tag=1
Build AABB tree...done (0.000999 ms)
Insert initial point set... done (0.001 ms)
Remesh...Legende of the following line: (#vertices,#steps,#facets,#bad
edges,#bad vertices,)
CGAL error: assertion violation!
Expression :
File : ../CGAL-3.6/include/CGAL/Surface_mesher/Surface_mesher.h
Line : 400
Explanation: Surface_mesher ERROR: A facet is not in conflict with its
refinement point!
Debugging informations:
Facet: (0x7f49340252c0, 2) = (-28.5 70.3082 -22.5545, -28.5 87.8543
-30.1016, -28.5 78.0193 -5.07986)
Dual: (-8.49794e+17 20.3612 -162.845, -25.7086 82.8197 -17.6368)
Refinement point: -0 82.8197 -17.6368
