Take a look at this YouTube video of someone playing with planets and rolling them down a hill in Second Life.
The technology behind this video was created by Havok the software programming company who program special effects for the computer gaming industry. Second life uses this physics engine to ‘perform collision and dynamics calculations for SL’
This next video shows the Havok physics engine being put to work for the Star Wars computer game.
It is intriguing to realize that we need objects to fall over, smash, crash and bounce in a virtual world so that we can feel more ‘at home’ within it. We want the laws of physics to accompany us ‘in-world’ and then we love to defy them.
I wish Einstein was still around!
