Vlad Bjornson over at ShinyLife has a video up on the new Havok4 Physics Engine that is now live on the BETA Grid:
In the video he stacks and rolls a bunch of balls (planets) down a nicely contoured landscape, ultimately landing in water. He also tosses around some blocks and other objects. I must say that the movements are considerably smoother than they are now. Jump over to his blog now to check out his video.
While at his site, scroll down and check out his sculpted prim waterfall and 1-800-FLOWERS entry. Very cool stuff.
