More interesting challenge would be to also keep metadata of the original CAD model such that you don't have a big BLOB on the voxel side. This would mean that during the tesselation process of each of the parts, somehow we need to extract this information. This is particularly useful if the original model is an assembly. It would be nice to also have this part information (and thereby the option to color correspondingly) in the voxel image.
This probably puts some additional effort in the tesselation part. Interesting stuff.... Marco On Mon, Dec 2, 2013 at 1:51 PM, Marco Nawijn <naw...@gmail.com> wrote: > I could not resist.
