Laurent Rineau 0f61f96c80 Merge pull request #5556 from MaelRL/Kernel_23-Dont_recompute_normal_in_proj_point-GF 
Fix inconsistency in normal computation in robust projection code
 2021-04-06 15:12:53 +02:00
Mael Rouxel-Labbé 48bb925b65 Fix inconsistency in robust projection code 
If the triangle/plane is degenerate, the case is handled separately.
If we know the plane is not degenerate, the normal should not
be recomputed in a different manner, which might lead
to a null normal and some issues down the line.

Andreas Fabri be39ec02fa Add a solve that 'returns' the denominator instead of making the division 2021-03-18 14:18:11 +01:00
Laurent Rineau b32250242a CGAL_Kernel_pred_RT for Do_intersect_2 and Do_intersect_3 
The code is not ready for that. A lot of overloads of
`Do_interesect_[23]` are implemented by calling the equivalent
overloads from `Intersect_23` (that requires division of coordinates).

Sébastien Loriot ba2f2c1c20 use FT instead of RT 
Compare_distance_3 is a generic functor that is comparing
the returned value of Squared_distance_3. If called to
compare the distance of a point to a plane/segment/triangle
a division is used leading to runtime error.

Laurent Rineau 2f4a32f089 fix Construct_projected_point_3 with degenerate triangles 
`Construct_projected_point_3::operator()(Point_3, Triangle_3)` now
checks if the triangle is degenerated (actually it checks if its
supporting plane is degenerated). If it is, it falls back to
`operator()(Point_3, Segment_3)` with the segment that is equivalent to
the triangle. When using non-exact floating point numbers, it chooses
the edge of the triangle that has the biggest l-infinity length.
