I'm sick of hearing about Chrome. I don't care. Please stop it.

I've been toying a bit with CSG, using BSP trees. Here's a cow and a dodecahedron. Here's the cow minus the dodecahedron.

The idea is to use this in a (possibly multiplayer) 3D space combat game where you can punch new craters on asteroids. With some basic rigid body dynamics, it could look really cool. Unfortunately, the BSP tree approach seems to generate way too many polygons. I also had a look at the approach to CSG used in GtkRadiant. It's based on implicit convex volumes ("brushes") - a subtraction operation generates new brushes on demand. It could be made to work in real time. Next I'll work on a demo where you can interactively carve holes on an object using both approaches in order to compare them.

And this looks incredible.
