Break Through in Gaming Rendering Technology?

[Craftyman.]

How does this work? Where's the catch?

AFAIK Animating something like this is a nightmare, and point cloud data requires a monstrous amount of storage and memory (like terabytes for a full game of unique points). Don't quote me on that though, just what I've heard.

Their "refute" of the "archaic" polygon system with their strawman comparisons makes me angry though.

Edit2: also I saw what was essentially this same video back in 2009 I think. I believe if there wasn't some massive inherent flaw in this type of thing it would be way more known/hyped/funded/what have you.
