Unlimited Detail


Recommended Posts

It looks similar to what Carmack was talking about (sparse voxel octrees). Note that Carmack didn't sound like he was going to eat himself when explaining it, though. He was very cautious and stresses the caveats / challenges associated it while also reinforcing the case for triangles. As usual, there is no magic bullet, so my money is on the "unlimited detail" video being implementation similar to what Carmack has already explained. If Carmack doesn't predict the end of graphics cards any time soon, then I'm happy to go along with him rather than this other dude.

Tech demo of sparse voxel octrees:

It looks kickass, but it has many limitations. Besides, geometry fidelity is no longer the final frontier IMO. We can now throw enough polys at stuff that it's not too bad -- this is why we're seeing a lot of new research going into screen space effects and advanced shading models rather than just blitzing through more and more polys. In short, I highly doubt this company's technology will be going mainstream in games. I don't think it's a coincidence that all of the environments in the video were both static and ugly -- the caveats aren't taken into account and there'll be a lack of decent tools. Is anyone going to switch over to some new fangled tech if it produces inferior results compared to what we've got right now?

It's like ray tracing -- people always show 30 reflective spheres in tech demos and people go "OMG!!11 look at that! It's ace!". Where does the rubber hit the road when it comes to games, though? Answer: It hasn't. There are no ray traced games that look half as good as triangle-based rendering because triangle-based rendering is well established and produces good results. I'm betting this 'silver bullet' turns out to be useful in some circumstances but that's about it.

doesn't sound far fetched from a technical perspective, although i am wondering what running time their algorithms must have and how they got them this low.

if this is real, i think it'll pose a much greater challenge for designers, however, especially in the creation of modular variation. if you can't use two trees that look the same because they look the same, you're going to design a lot of trees...

maybe its just my machine but the video looked like ti has really terrible framerate i

that said was DEMANDING an atom based game engine since ... well longer than i can remember ! so i want this shit badly

and i bet all the "detail" is still derived from polygon based zbrush models and stuff :D :D :D

It probably isn't the way to go for ultra realistic detail, seems like realtime tesselation has the edge atm, but man I always wanted to do something with a voxel(/point-cloud) based engine. Where are all the digging/building/crazy material manipulation voxel games? The tech has been there for years, check out ken silverman's demos: http://advsys.net/ken/voxlap/voxlap03.htm

This stuff could probably run on a nintendo wii, maybe even iphone!
