Since I seem to have convinced myself that I need to rewrite the game in THREE.js instead of BabylonJS, I’m going to take a minor break from working on collision detection.  As I said in my last post basic collision detection and response is working.  It’s still a little glitchy and needs a lot of work to be applied generally, but since I know it can be done I think I’ll put Penrith Forest together with THREE.js and then try to get the collision detection and response system in place from there.
