m.overtheil 9a7660b6fa Added compatibility for traits without dimension_tag 2014-11-03 11:15:49 +01:00
m.overtheil 8f94bc329b Replaced all int dimension with dimension_tags 2014-10-31 15:02:04 +01:00
m.overtheil c0a37c0a05 Bugfix for Sliding_midpoint splitting rule(default) 
Fixed a bug causing the tree to have linear depth in some degenerated
cases, e.g. when points are on a segment or on a hyperplane in general.
Added a check of the tight bounding box to avoid that.

Also set the default bucket_size from 3 to 10, which results in much
better runtime.

Mael Rouxel-Labbé c0cbdab3d8 Fix a bug in Spatial_searching's fuzzy_sphere 
The contains() function (and its variations) returned false
for all points on the sphere.

Mael Rouxel-Labbé 5ed7255adb Fix a bug in Spatial_searching's fuzzy_iso_box 
The contains() function (and its variations) returned false for
all points points P(x,y,z) such that x=box.xmax() or y=box.ymax()
or z=box.zmax(). This excluded some points from being found when
querying a kd tree.

Eric Berberich 9d8a02aa46 rephrased documentation for capacity in Kd_tree 2014-03-28 14:50:18 +01:00
Waqar Khan 98e6007dd3 * Added the capacity() function to the Kd_tree.h and also added its documentation 
* Added a test that checks the reserve() and capacity() function for Kd_tree

Eric Berberich 85894658ef fixed copyright headers 2014-03-10 00:03:24 +01:00
Waqar Khan 1c355ef42a 1. "Snap_rounding_traits_2.h" "Snap_rounding_kd_2.h" "Kd_tree.h" "snap_rounding_data.cpp", Changed the File header signature to match the templated signatures. 
2. Made the required changes in the concepts i.e. in "Snap_rounding_2/doc/Snap_rounding_2/Concepts/SnapRoundingTraits_2.h"
 3. Added documentation for the reserve() method of Kd_tree
 4. Deleted the un maintained olk kd_tree package
 2014-03-07 16:13:44 +01:00
Waqar Khan 0e14493632 1. "snap_rounding_data.cpp" Added Example usage in-code documentation. Removed the timer that recorded the amount of time taken by the snap_rounding. The timer was initally added to test the snap rounding running time difference using new Kd_trees 
2. "Snap_rounding_kd_2.h" "Snap_rounding_traits_2.h" Added documentation and changed Copyright information and authors appropriately.
3. "kd_tree.h" Renamed the reserve_to_capacity() to reserve().
4. Snap_rounding_kd_new.h deleted

Sébastien Loriot 0b3c2ae383 fix a documentation bug and add static assertions 
the class Search_traits_adapter must use only Lvalue_property_map since
  it uses the Cartesian_const_iterator from the base class which is usually
  simply the pointer on the double in the point. If the point returned by
  the property map is a temporaty, the iterator is invalid and its behavior
  is undefined
 2014-02-21 15:36:40 +01:00
Waqar Khan b46b37e7b2 reserve_to_capacity() method for Kd_tree.h that pre-allocated memory for points added. New Snap_rounding example added where the input data is taken from a file. Snap_rounding_kd_2.h modified to use the reserve_to_capacity method before creating the kd_tree. This improves the running time. 2014-02-18 01:41:44 +01:00

Sébastien Loriot 69b2f7079a BUGFIX: 
incremental neighbor search classes were storing a nested ref_counted iterator
for begin() which implies that a call to operator++ on a copy of an iterator
increment the internal copy of the class (cannot make several pass).
There is still a problem in case of copy outside of the class but this is
a first step (a deep_copy method should be provided for iterators which would
need a small feature).

Sébastien Loriot 751f3ba08b the class Kd_tree is now read-only thread-safe using a mutex. 2011-09-08 16:12:51 +00:00
Sébastien Loriot 37b02012b6 fix const-correctness issue in the spatial searching package. In particular this 
remove all mutable member variable and leave only one const_cast in the kd-kdtree private function
const_build. This function is called in const predicates when the tree is not already internally built.
The documentation has been update and a few typos fixed at the same time.

Laurent Rineau 3d1fd31b75 Bug fix in <CGAL/Fuzzy_sphere.h> 
Fuzzy_sphere_3<Search_traits> tried to use Point_d::dimension(), instead of
using Search_traits::Construct_cartesian_const_iterator_d. With a custom
Point_d, there was a compilation error.

Sébastien Loriot 5ee07db31f operator= of iterator: do nothing when internal ptr are the same. 2010-10-22 13:17:52 +00:00
Sébastien Loriot d07f78578a add parenthesis to indicate how an expression should be evaluated. 
This was done so that an assertion of Orthogonal_incremental_nearest_neighbor does
not fail in case new_off == old_off (when using floating point arithmetic).

Sébastien Loriot 93b2b7cbac Add bounded priority queue as an internal data-structure. 
Use the bounded_priority_queue inside Orthogonal_k_neighbor search
and K_neighbor_search, a maximum of code is now shared by these two classes.
This reduces computation time and memory needed.
Extend the interface: to save time the sequence  k-nearest neighbors 
can be sorted (default) or not. 
Add a new test that ensures all methods find the same kth closest neighbor.
Update manual.

Laurent Saboret 91f0bbfe23 Optimization: 
Store the neighbors found in a std::set, instead of a list sorted by insertion sort (in type NN_list). 
This makes insertion O(log n) instead of O(n).

Sylvain Pion ef264999b3 Renaming of Compact_container's construct_insert() to emplace() to match C++0x. 
It breaks backward compat, but I doubt many people use Compact_container directly.
