Aaron Trocola @ Engineering.com wrote this nice piece about how volumetric representations, "models that are not just a 2D surface in 3D space" (a mantra here at Uformia), will help to bring about the end of polygons (at least for manufacturing). He contends, as we do, that volumetric representation allows for more complexity in designs going out to print (too many discrete features can result in a polygonal representation that is too heavy to calculate) and will also bring about multi-material printing.
We applaud Aaron's words, and thank him for acknowledging Symvol as a potential software solution towards this end.
A note on solids and solid modeling -
We should also mention that we are not a voxel or discrete based modeler (although we can bring voxel data into our system). Our technology is to voxels what NURBS or parametric solids are to meshes and we are always watertight by default. As well we already offer experimental multi-material modeling inside our API (more about that later).
