Dear gouessej and jmaasing,

My approach is simple; If you can draw it you can pick it. And it's fast enougth; Picking is never slower than drawing and usually about ten times faster.

You claim that doing things on the GPU cannot be faster than doing it on the CPU. Of course it can! That's why we've had dedicated graphics hardware for a long time and that's why these cards are now being opened up to make their massive parallelism available for general computing.

So with all due respect, if you want to claim superiority of your oldfashioned hierarchical "software" approach of yesteryear the burden of proof is on you. Good luck.

I've understood that you prefer to discuss your pet ideas but my interest in this really is just the OpenGL porting issue. Thanks.
