OK, I did not expect this :-)
6000 spheres versus floor = hellishly fast simulation :D
Due to technical problems with ODE, I decided for my implementation(with HDK) of Bullet solver.
Does not currently support multi-thread(so simulation using only 25% of CPU), and I support only the basic sphere and box objects (convex and concave comming soon).
I tried play the scene from file-cache, but its slow, so Its not in this video.
Loading more stuff…
Hmm…it looks like things are taking a while to load. Try again?
