Pierre Alliez a86c346e54 AABB: implemented two new functions suggested by Andreas: 
void clear(void)
bool clear_and_insert(begin,beyond)
 2009-04-28 15:29:37 +00:00
Stéphane Tayeb cf794d7a17 add forgotten file (r48979). 2009-04-28 15:14:34 +00:00
Stéphane Tayeb 7d85cbdd57 * Remove ad-hoc code from AABBTraits: 
- add nearest_point_3(Point_3, Triangle_3, Point_3)
  - updates Projecting_traits of AABB_tree
* Fix test compilation (linux x64).
 2009-04-28 15:12:51 +00:00
Pierre Alliez 6c4f25b95b AABB: rename to less_x/y/z 2009-04-27 18:13:06 +00:00
Pierre Alliez b563d29270 AABB tree: the projection does not construct the KD-tree at the first projection query anymore. for efficient projection queries either the user calls for its explicit construction during the AABB construction or calls "construct_search_Tree()". otherwise the first primitive reference point is used as (naive) hint. 2009-04-27 15:36:35 +00:00
Stéphane Tayeb 50a9d76db0 Fix polyhedral oracle. Add class AABB_const_polyhedron_triangle_primitive. 2009-04-27 13:25:46 +00:00

Pierre Alliez 18c93be7bc AABB tree: replace xref/yref/zref and point_on by a single reference_point() function for primitive. 
NOTE: the reference point is used both for sorting the primitives and for constructing the search KD-tree

substantial complication... may be improved.

Pierre Alliez 24e3bc0c22 AABB tree: added two primitive types for triangle and segment to make two examples simpler. 
rename Object type to Datum type within primitive as it was conflicting with CGAL Object type
 2009-04-26 13:46:48 +00:00

Pierre Alliez f01b6e147f AABB tree: important pass on the documentation from A.Fabri's review and several discussions with S.Tayeb, L.Rineau and C.Wormser. 
remove all _type suffixes to types
distinguish datum from data
A primitive wraps a "geometric object" and an Id - not a primitive and an ide (confusing)
added any_intersected_primitive() to be consistant
 2009-04-24 09:42:43 +00:00
Stéphane Tayeb c4b6628106 * Projection query correction. 
* Remove old code.

Pierre Alliez 31992dd000 AABB tree: things to be fixed (intersections) 2009-04-21 12:29:26 +00:00
Laurent Rineau 3654111856 Ooops: fix a bug I introduced myself since revision 48240, which was: 
" - Rewrite of longest_axis(), which was quite strange, and switch to double,
      as CGAL::Bbox_3 coordinates are always double."

That fix will re-improve the query time.
 2009-04-10 17:02:54 +00:00
Laurent Rineau 58f1842820 Improve again the construction time of an AABB_tree (by factor of 5 to 1). 2009-04-10 17:00:10 +00:00
Laurent Rineau 7a340e9d8d Improve the construction time of an AABB_tree for free (by using 
std::nth_element, instead of std::sort).

Laurent Saboret 425cc63967 Fixed compilation warnings with VC++ 2009-04-07 14:01:14 +00:00
Laurent Rineau 69cc456852 typo : lenght -> length 
(Thanks to Sylvain Pion.)
 2009-04-06 12:25:12 +00:00
Laurent Rineau 9b9d32c208 The polyhedral oracle can now be used by Mesh_3. 2009-04-06 12:10:42 +00:00
Laurent Rineau 85bd8c4adb Add a member function AABB_tree::count_intersections 2009-04-06 12:10:09 +00:00
Laurent Rineau d51fcf2fa2 Make AABB_node::max_lenght public, so that AABB_tree can use it. 2009-04-06 12:09:32 +00:00
Laurent Saboret cb2644dab9 Revert revision 48625 that does not compile with g++ 2009-04-03 17:26:19 +00:00
Laurent Saboret 7d659c7483 Fixed compilation warnings with VC++ 2009-04-03 12:38:46 +00:00
Laurent Rineau f86c071b04 - Add constness to AABB_tree, 
- Add a method bbox() to AABB_tree, that returns its bounding box.
- Add a method size(), that returns the number of nodes.
- Add a method traversal to AABB_tree, so that one can call it with a
  user-made traversal traits class.
- Add a Drawing_traits traits class, that draws the tree with OpenGL.
- Add predicates and constructions so that one can call
  AABB_tree::intersection with Kernel::Plane_3 as query, and Segment_3 as
  result type.
- New query function AABB_tree::all_intersections.
- The member function AABB_node::intersection is now templatized with a new
  template parameter 'Result', so that the result is not hardcoded to be
  'Point'.
- Three new constructions, for the intersection (and not only do_intersect)
  between a Triangle_3 and (Plane_3, Ray_3, Segment_3).
  (NOTE: That has not been tested intensively. And the intersection with
  Ray_3 and Segment_3 does not handle co-planar intersections, for the
  moment.)

Laurent Rineau 9f3a3e323b Fixes for non-Windows compilers. 2009-03-30 14:05:56 +00:00
Laurent Rineau e13b94d625 Factorize the code between Ray/Line/Segment, using templates. 2009-03-02 11:10:37 +00:00
Laurent Rineau 288525ba5f - Rewrite of longest_axis(), which was quite strange, and switch to double, 
as CGAL::Bbox_3 coordinates are always double.
 2009-02-26 18:04:56 +00:00
Laurent Rineau 25d930749f - Move the traits First_intersection_traits from AABB_node to AABB_tree. 
- Remove AABB_node::first_intersection which is useless.
- AABB_node::traversal is no longer templated by Result_type. Instead of
  passing as argument a 'result' object, and constructing a traits at each
  call, the traits object is constructed once, before calling traversal,
  and passed as argument.
 2009-02-26 16:40:40 +00:00
Laurent Rineau 641fa903d8 Yet another move of a function, and add comments. 2009-02-26 11:48:17 +00:00
