Sorry to be a bother! However, we are still unable to proceed with our CGAL backed Delaunay implementation due to the bug described earlier. Is there any more suggestions out there and, if not, are there any developers in particular who work in this portion of code that I could perhaps contact? Thanks in advance.

I tried adding the CGAL::force_ieee_double_precision(); call to my code, but with no luck. Certain data sets still make the Delaunay triangulation crash. It might be worth noting that we are only adding points to the triangulation that have distance greater than or equal to 0.001 from any other point currently in the triangulation. therefore, it does not appear to be a problem with points being "too close" together. Any other thoughts?

You may try :

#include <CGAL/FPU.h>

and

CGAL::force_ieee_double_precision();


at the beginning of your code.




it should at least help to have the same behavior
if your ar in debug mode or not.
