Laurent Rineau a3587eabf3 A version with less branches and more numerical computation 2012-06-15 15:12:04 +00:00
Laurent Rineau 41ba29e19a Factorize code of Do_intersect(Bbox_3, <something>) 
Uniform use of do_intersect_bbox_segment_aux(..) with various Boolean
template arguments.
 2012-06-15 15:06:34 +00:00
Laurent Rineau a72bd80380 Pass the bbox as argument instead of the six coordinates 
That increased the perfs! :-)

Laurent Rineau 503d441f1e merge changes from next 2012-06-13 15:51:29 +00:00
Sébastien Loriot ace74a2bab Object::empty() is !variant::operator bool () 2012-04-24 16:57:58 +00:00
Philipp Möller 17797b7271 Merge next into this branch. There have been conflicts in the 
AABB_tree documentation, Intersections_3 and Arrangement_on_surface_2.

The merge also introduced a regression for a bug fixed in R68387 which
fixed a bug in Triangle_3 Segment_3 intersections. The relevant
testcase is in triangle_other_intersection_test.cpp.

Laurent Rineau 6c705ab777 Fix the test 
One cannot expect exact intersections computations results when the kernel
is not. This patch fixes the test: the equality between the result and the
expected result is tested with an epsilon unless the kernel has exact
constructions.

Sébastien Loriot 8db3036330 BUGFIX 
correct error in intersection computation of triangle_3 segment_3
when the segment is collinear with a triangle edge.

Sébastien Loriot ab57806db7 missing enum_cast 2012-03-22 11:08:05 +00:00
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)
 2012-03-21 11:49:30 +00:00
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 b5703e9cf8 Add a note about a test that is already covered by previous test. 2012-03-16 16:14:47 +00:00
Laurent Rineau 58809c064a Full test suite of do_intersect(Bbox_3, Segment_3). 
I have tested with gcov that all branches of the predicates are tested.

Laurent Rineau bd09875fea Add a few test cases. 
One of then use boost::math::nextafter to move around a critical
 case. That is strange that even non-exact FT can deal with that without
 filtering.

Laurent Rineau c0a37addfb Also test with Sc<Gmpq>. 
Simple_cartesian<Gmpq> is a non-filtering kernel whose FT is not a IEEE 754
type. That number type is interesting to test with.
