Watch the Away3D and WOW demo. Sometimes they stand like a tower and sometimes it almost look like they explode. Click on the onderground to reset the cubes to a random position
I started with the tutorial from Fabrice Closier port it to Flex and just play around with the options of WOW. One minus point of the WOW physics engine is that they are in a really early stage. You can only use Spheres and it isn’t rotating if they collide. I was pretty fast bored with the Spheres and I started to hack some extra shapes in. First a plane (what looks terrible if it isn’t rotating) and then a cube. In the collision detection I added the cube and now he can collide with the spheres and other cubes.
