You know the thing I always find very funny about these voxel discussions, is that inevitably the issue of memory comes up. The common argument I then hear is that "Ok, well you can just compress the voxels down". The underlying reason why this compression works is that most 3D volumes are piecewise constant (ie have low variation), and so they can be substantially compressed using run-length-encoding. In 1D, encoding objects into runs can be done efficiently by using interval trees (which also permit efficient random access/traversal). For 2D and higher, this doesn't always work as well and so people tend to resort to approximations of these runs using quadtree/octree covers.

But let's take a step back: what all this really relies on is the fact that voxels can be represented by just keeping track of the transitions in these constant levels. This is precisely the boundary of the object. Taken to the logical extreme, what this basically means is that the best compression anyone can reasonably hope for in a voxel data set is to ultimately reduce it to a B-rep anyway! So what was the advantage of voxels again?

(Note that this argument doesn't apply to volumetric data sets with complex internal structure or high variation, such as the maps in minecraft or MRI data.)

By the way, there is an older thread (Januaray 2010) on this. Here's he link. Anoter engine, the Atomontage engine is also mentioned in this thread. There are plenty of videos on youtube (here's one) and a nice site for this engine. You should check it out. It looks far more complete than unlimited detail and there is also decent art in the demos. The engine is actually hybrid and uses the GPU too.

So in this video:

They are showing that:
a) It can easily be animated
b) It has zero problems with memory size issues
c) It is unlimited

So seems all blaming comments here was just jealous.

All I see are more unsubstantiated claims and a decade of work with no released product other than promotional video. Sorry if I don't find that convincing.

Yeah, let me know when they release a white paper.

Also, if anyone is looking for a challenging drinking game, watch that video and take a shot every time you hear the world 'unlimited'.
