I re-integrated a physics engine, this time BEPU physics, which is a screaming fast open-source XNA physics engine with unbelievable support. I was able to get my existing block simplification/rendering code to work with BEPU, so now you can add/remove blocks to/from existing objects on the fly. One cool side-effect of this ability is that I can also blast objects into smaller chunks... full-blown destruction is #1 on my list right now.
I also wrote a simple deferred renderer so I can enjoy practically unlimited point lights! Motion blur and bloom came as part of the deal. There are still some quirks with it, and I hope to eventually cover the whole thing in a few articles as I encounter issues.
Observe this tasteful, expertly-crafted demo video. And no, Parkour Ninja is not turning into Minecraft! I just needed a way to demonstrate the mutable physics objects, and clicking to remove blocks was the easiest way.
