I’ve just uploaded some videos showing the shadow support in action. Check them out:
The Lightcycle demo is more interesting due to several factors. First, it’s a Lightcycle from Tron :). Secondly, it shows self shadowing. And third, it display several rendering artifacts that are yet to be solved. Notice how the shadow is shaggy since there is no blur in the map itself. Also, there is a little acne too (mostly in the wheel section).
