Wow, that sounds pretty fantastic. How do you integrate Adrian Egli's K-D
tree implementation into an application that uses OSG?
I appreciate all the hard work everyone does. I appreciate it to the tune
of $25. (actually, I appreciate it much much more than that, but it is
about all I can affor right now. I know its not very much, but its a
start. I also will go ahead and donate $25 to the OSG in general. Heaven
knows Robert has done so much for every project I have worked on that uses
OSG.) Maybe someone else can add to the pot?
Are you manning this competition Adrian? What are the other rules? I just
want to make sure that I (as an OSG noviciate), and everyone else in the
community, can use these great optimizations.
