R-Trees: A Dynamic Index Structure for Spatial Searching

Description

A C++ templated version of this RTree algorithm. The code it now generally compatible with the STL and Boost C++ libraries.

Usage

#include <RTree.h>

// ...

RTree<Foo*, double, 3> tree;
double min[3] = {0., 0., 0.};
double max[3] = {1., 1., 1.};
Foo* bar = new Foo();
tree.Insert(min, max, bar);

Provides search in and iteration over the tree. For examples see Test.cpp

Testing

Run make to build and make test to run the tests. The RTree itself is a single header file and can be included without compiling.
