Nice!! If you plan to use kdtree's, maybe you are interested in the
following kdtree implementation:
http://svn.gna.org/viewcvs/getfem/trunk/getfem/src/bgeot_kdtree.cc?rev=3454&view=markup
where I have recently contributed the nearest neighbour search part.

Thanks for the quick response, so that I don't have to invest more
time in this issue.

Kind Regards
