Why quaternions?

We can represent 3D rotations in a variety of ways, arguably the most useful of which is the matrix. In three dimensional space, a 4x4 matrix usually defines the world transform of an object, because it can contain lots of information: translations, rotations, scale, and lots more. But when we're talking simply about rotations, there's […]

Away3D 4.0-beta

I've been fooling around with the Away3d 4.0-beta lately (for FP11!). I wrote a quick demo--it's using Box2D on the XZ plane, and I'm faking the Y physics. Try it out! Arrow Keys move. Spacebar shoots. Enter jumps. If you time it right, you can jump over the wall! Link here.
