Hi guys,
I am having an issue trying to use Sibsons C^1 interpolation on my data. If
I use Exact_predicates_inexact_constructions_kernel, then
sibson_gradient_fitting_nn_2 fails with the error:
terminate called after throwing an instance of 'CGAL::Assertion_exception'
what(): CGAL ERROR: assertion violation!
Expr: ! CGAL_NTS is_zero(den)
File: /usr/include/CGAL/constructions/kernel_ftC2.h
Line: 62
If I use Simple_cartesian<long double>, then the process hasn't crashed, but
did not finish after over 24 hours. This is with an unstructured mesh with
~2.7 M triangles after triangulation.
I suppose this is a numerical error. Is than any known workaround to this
problem?
