Sparse Voxel Octree (SVO) Demo by Jon Olick

This demonstration of real-time sparse voxel octree technology was debut at Siggraph 2008.

i wouldnt want to go "all night" with that beast.

i think the music is unfitting.

[zelexi]

@ImTheWackhead So true. I need to fix that.

@Tableuraz This was done in 2008 (3 years earlier), with a GPU which was 8 times less powerful than the one UE3 used in their latest tech demo. ;) And the model IS textured with a light probe from Paul Debevec.

[zelexi]

@Tableuraz Also, UE3 wasn't 60 fps on consumer grade hardware.

I'd be much more inclined to believe this was the future of game rendering, if that fella were moving around, breathing, and showing the kinds of deformations we take for granted in polygonal rendering.

99999999999999999999999 voxels in this model... maybe more

@olilittle Trace rays in the scene onto an animated simple bounding mesh, which is then used to translate the rays into mesh coordinates in the base pose, that are then traced against the original static voxels. So the voxels don't actually move, but your view of them does. Need to take care to deal with intersecting animated mesh - trace twice through the voxels.

[olilittle]

Tell me, what do you plan to do about animating said voxels?...

@Haroids Why would it be impossible? The poly-count isn't very high at all compared to current generation games. And even if that is what you mean it wouldn't be impossible, just slow to render. Unless you mean impossible in some other strange way. Care to elaborate?

[MrEggBass]

It's like a photo, but then 3D :o

@RFC3514 Notch uses voxels to define the shapes of the blocks. If he didn't use voxels, it would be impossible to render all those cubes you're able to see on-screen.

@noobenstein - Minecraft does not use voxels to render the terrain. It's uses a pretty standard polygonal renderer. It just happens to use a blocky 3D grid to _define_ the terrain, which is a look people normally associate with (low-res) voxels.
