Chrome Physics

You should all read Jakobsen's paper on this subject Advanced Character Physics "http://www.ioi.dk/Homepages/tj/publications/gdc2001.htm".

It explains the technique used in Hitman (particle-physics using Verlet integration with constraints using a relaxtion loop). The cool thing about Verlet integration is that with a fixed timestep you get a Very Fast integration. And because of the properties of the Verlet integration, constraints can be handled by simply moving the particles to a new position (which might invalidate other constraints) and then just keep doing this for all constraints until you've reached a good enough result (for soft bodies, like plants in hitman, you could do maybe only one or two relaxations, that way the body will slowly stabilize over a few frames). This isn't a perfectly analytical solution to the problem but it is VERY easy to implement and is probably 10x faster than normal rigid body dynamics.

So it's not 100% accurate, but very very close, and very very fast so that's good enough for games. Verlet integration rocks! =)

Whatever. Like god created the universe to follow formulas. :P

HOLLYWOOD FAZACKS !!
what's hitman's physics like?

Very pretty, but...please don't suck ass.

More games need Hitman like physics
Best thing in that game..
