GigaVoxels : High Quality Realtime Sparse Voxel Octree Ray-Casting

This video illustrate our GigaVoxels rendering pipeline. It is based on sparse octree ray-casting of very large voxel scenes.

Mightily impressive visuals, indeed, but everything shown here is static models and environments. Putting all this into a dynamic virtual world would require some extra massive computational resource, as all tree-bounded structures out there. And the memory requirements for hi-detailed definition are quite pressing, too.

But Voxel have a big advantage -- a truly "natural" LOD scaling system for both shape and surface detail, as they are a single defined structure, unlike triangle rasterization.

there is a videogame based on voxels.... its called outcast and its from 1997 AFAIK^^

Argh. I can't post links here. Please look at my profile if you're interested in the iOS voxel renderer.

[kit3bus]

Very interesting! Any chance I can try the models with my iOS renderer?

VOXEL=MINECRAFT BASED THING

2:15 is like a maze in hell.

I think tesselation has eliminated the need for LOD Voxel rendering techniques for a while. I can scale level of detail on basically anything as much as I want using tesselation

This looks much more advanced than "Unlimited Detail"'s voxel engine.

@YourPreciousOne I completely agree with you, and well done GigVoxel a lovely piece of tech your showing here.

With respect to the voxel nemesis that is animation Dennis Bautembach has done work on animated sparse voxel octrees there is a significant performance hit but the work is still very impressive. In the short term perhaps we will see a hybrid engine with voxel based static geometry and polygon based animation as we saw with doom which used sprites and polygons.

Åh, it's beautiful! :D

... but that last example was truly gross! @~@

@MetrotomX5 We moved away because we didn't have the computer power to run games with voxels, THATS WHY!!! Imagine a whole game like this, 0.00000000000000000001FPS at best!

Aspect ratio FAIL.
