Sébastien Loriot ba760bbdb2 need to use an enum for having the different cases: 
when the end point is on the facet, any ray have the endpoint in the
plane of the facet.
 2012-03-22 10:39:23 +00:00
Sébastien Loriot b058a2a4f3 modify the internal do_intersect Ray_3 vs Triangle_3 function 
to be able to known whether the endpoint of the ray lies inside the
plane of the triangle. The running time is the public do_intersect function
should remain the same.

Laurent Rineau b5d987a4b5 Increasing the perf of the filtered predicate 
When FT is Interval_nt, it is better that the
Do_intersect_bbox_segment_aux_is_greater returns a Uncertain<bool> instead
of a bool. That can delay the conversion of Uncertain<bool> to bool, and
hence better perf.

Laurent Rineau e940d97a75 Prepare the code factorization with the static filter of Do_intersect_3 2012-03-21 13:59:45 +00:00
Laurent Rineau 0e6dbc4b40 Reorganize expressions that are evaluation of the sign of a determinant 
There are six of them in do_intersect(Bbox_3, Segment_3)

Laurent Rineau c291e92442 Less tests of sign of expressions 
Followup to previous commit.

I have managed to transform most of the tests to simple comparison of input
coordinates. That will ease the writing of static filters. Only six
determinant signs have to be exactly determined.

Laurent Rineau fb796dbc97 Missing match for Intersect_3::operator()(Ray_3, Triangle_3) 
There was only Intersect_3::operator()(Triangle_3, Ray_3).

The specializations for CGAL::intersection were for both order however.
