Hi,
Sorry to interrupt you on this function in CGAL. Currently I use
Exact_predicates_exact_constructions_kernel as kernel type to compute the
intersection of two polygons (as attached, 0.txt and 1.txt). However, in the
result (2.txt), I always find that there are two points who are very close
to each other (Points 2 and 3), which affect the calculation very much.
I'd like to know if it is the problem of my data or that of CGAL please? If
CGAL, then why it occurs and how it can be avoided please?
Thanks very much!
