I just downloaded the demo and I see some corruption on the planets. It happens on all the planets. Screenshots: http://i341.photobucket.com/albums/o370/Numerator/SVT.jpg http://i341.photobucket.com/albums/o370/Numerator/SVT2.jpg -Doug

It looks like everything's corrupted. As I mentioned in various notes, I didn't actually try to make it robust on all hardware--it doesn't have fallbacks and it probably doesn't even check for extensions and just tries to use them. The goal was a robust algorithm, not a shippable implementation. It worked 100% on both by desktop and my laptop machines, but who knows beyond that. (I think the desktop was an nvidia part.)

I am using an NVIDIA GeForce 8800 GTS 512 with a recent driver,which should support all the same extensions. I have not investigated the source of the corruption, though. I guess the take away here is that a robust implementation would need to be run on a variety of platforms and have fallbacks as is typical of PC applications. This why a PC is not just one SKU. Thanks for the presentation and posting the code. EDIT: I am using Vista 64 as well.
