You're right. They're not that different though.I've messed around with the NaturalMotion program by Euphoria and I have to say it's a hell of a lot more realistic than ragdoll physics.
Edit
Err... The program was actually called Endorphin, not Natural Motion. NaturalMotion is the name of the company. I apologize for the mistake.
Could you imagine the euphoria engine or at least one of it's successors used as the program to control an android's motions?Euphoria = Skynet
I'm already ****ting bricks.
