Voxel based modeling from Siggraph

Shrike

Seems like a pretty interesting approach for high poly
Non destructive and with primitives and modifiers in comparison to voxel sculpting

3D Coat already has voxel modeling but one caveat. Voxels are memory intensive, while zBrush is not as memory intensive, that and zBrush is mainstream in most pipelines.

Houdini has plenty of volume fiddling tools and Dynamesh is obviously volume based too

However, it's nice to have the stack/UI attached and the live editing stuff..
If they'd only put it in an application people use....

I like that "generate volume from some curve scribbles" thing, that's pretty slick!

Of course does 3d coat / zbrush have voxel based modeling but the approach is a lot different. In the presentation it was all done with primitives in a non-destructive stack, which is basically the opposite of sculpting voxels per hand with brushes or already collapsed meshes as A/B cutouts
