> Don't take it personally, I didn't mean it's slow at 100k intersections

> traces in a sphere at each vertex and then stores that as vertex
> attributes in the Spherical Harmonics basis... Your program is just
> raytracing from the viewpoint and displaying that, which is simpler...

> And I recently integrated the last version of your kdtree in my
> application, and it works well... If you have a newer one, you can send
> it to me if you want... :-)
