Hi Stephen, Unfortunately, we will need to call the kD-tree many, many time in succession from with a Cython routine, as well as maintain multiple extant kD-tree objects simultaneously. My recollection is that you use Forthon because the first is not possible, and I also seem to recall the latter is somewhat difficult. Additionally, the usage of the kD-tree inside compiled C code would make it a compile-time dependency... What do you think -- does this agree with your understanding? -Matt On Sun, Jan 9, 2011 at 11:38 PM, Stephen Skory <stephenskory@yahoo.com> wrote:

simplest implementation; it uses a kD-tree I grabbed off googlecode, which we'll ultimately want to replace with something faster,

I can help if you want to try using the Fortran kD-tree with this, all. Let me know.
