Interesting. Meshmixer works in a similar manner to the VDB tools in Houdini (it's solidifying and hollowing tools are based on voxels). I can see how it's useful for it's designed purpose in 3d printing but it will be interesting to throw some lower poly stuff at it and see how much of the topology survives the process.
