but crytek doesn't do any preprocess for LPVs, right? so they're generating that voxel grid in real-time by deconstructing/resampling gemoetry?

from what i can tell the ring isn't touching that surface at all, which is not merely an illusion of the reduced shadow accuracy since it looks like they're using direct and indirect shadow maps there. i mean, you can see a mild peter pan effect during the camel's run, for example, but that's acceptable as far as i'm concerned.

looks like LPVs are an optimized variant of point-based/fuzzy GI? i was convinced they were doing general light transfer without considering the shadow problem, but i guess that's kind of impossible given if you have enough bounces in any solution you're gonna get some indirect shadow, right? though that might depend on how you handle your ambient light.

i don't yet have enough programming experience in this area to properly make sense of these techniques. i mean, i realize crytek is dealing with vast geometry and effect overhead, so whatever the effect its use is gonna be limited in their games, but it seems i was pretty mistaken about their methods.

^edited this a bunch. sorry if it's a mess for anyone reading.

not ruled it out so much as i've never seen convincing results. and i don't know much about the technique. but what games use it besides crysis 2 and a handful of upcoming ce3 games? even crysis 3's indirect lighting is remarkably flat, but i imagine their tradeoffs are steep.

if i experiment with the sdk can i hope to see results like what i posted?
