+    A d-dimensional point class which is written carefully using templates. It allows for basic

+    supported using <a href="http://www.cs.berkeley.edu/~jrs/">Jonathan's</a> code. This class

+

+ \section intro Introduction
+ <table border="0">
+ <tr><td>
+ If you do not know, what a Delaunay triangulation is, you can read more about it
+ <a href="http://www.compgeom.com/~piyush/teach/5930/slides/lecture8.ppt">here</a> and
+ <a href="http://en.wikipedia.org/wiki/Delaunay_triangulation">here</a>.
+ This C++ library module is just a wrapper class on the
+ <a href="http://www.cs.berkeley.edu/~jrs/">Triangle</a>
+ package of <a href="http://www.cs.berkeley.edu/~jrs/">Jonathan</a>.
+
+ Many times I have had to use triangle in C++ code bases of mine and have been forced to use C.
+ At last I thought I would put a wrapper on his cool C code and it seems that this is what I got.
+
+ The design is not perfect and the code was written in a day, but it does compile and run on the
+ machines I tried (cygwin/redhat). The C++ wrapper will certainly slow access down if you want to
+ mess with the triangulation but the basic delaunay triangulation should be as fast as triangle.
+
+ Look at the tpp_interface.hpp file for getting started on what this wrapper can do for you. Also
+ have a look at main.cpp which shows an example of using this class. The class is thread-safe.
+ <p>
+ <b>Requirements</b> : Python, make and C++ compilers.
+ Supported C/C++ Compilers: g++ / icpc (Intel C++).
+ Also needed is doxygen for generating documentation.
+ </p>
+ <p>
+ <b>Compilation</b> : Just type 'make'</p>
+ <p>
+ <b>Testing</b> : Goto the bin directory, and type './test ../data/input.dat' (after compilation of course).
