Wow. Just, absolutely wow. I was first turned on to your lidar.exe game, and then found THIS! Just trying to figure out what's going on, blew my mind.
A question, Ken, if you might: Have you ever snapped a photo of the moon while you're falling toward it, and then looked down and popped a hole through the moon, with another moon to fall onto? It can get REALLY WEIRD, really fast.
Another question: How does the algorithm decide how to color the "cut" surfaces? That is, new surfaces formed by cutting old objects with empty space?
And a suggestion: If you ever do part 2, you could add a zoom lens! I'd have to work out the projection math, but I *think* it would allow possibilities that aren't there now.
Can I send you, like, $40? You've made my month :-)
