In the past I have experimented with the use of the ape physics engine and papervision3d together with some interesting results. Box2D is another physics engine available for flash, so I thought I would do a small test to see how that integration worked. As a whole I would say that ape physics is a fair bit easier to use, but Box2D is a lot more powerful. Here is a quick experiment with it.
I also noticed a small papervision bug in this example. As you can see there is a weird glitch at times. It is occurring whenever I add a new 3D object into the scene. I can’t seem to track down what exactly is causing this. Update: On further examination this bug was not a papervision bug, but rather a mistake in how I was reading the display list from Box2D. It’s display list adds items onto the beginning rather than the end, causing the error to occur.
Also notice the nice shading on the cubes, that is the power of papervision3D 2.0.
