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. -- Rick On Mon, Jul 14, 2008 at 7:57 AM, Adrian Egli OpenSceneGraph (3D) < [EMAIL PROTECTED]> wrote: > Hi all, > > ....................
