Recently there's been some interest in using CAD for jewelry design.
I'd like to share this paper describing the new UDT tools in Rhino
4.0. (UDT stands for universal deformation technology). (I have no
affiliation with the authors or sponsors of the UDT I
just think it's pretty amazing stuff).
Rhino is approaching the finesse and fluidity of ArtCAM's digital
sculpting tools, but for relief modeling, ArtCAM still offers more
design freedom and control with it's texturing tools and especially
with the sculpting tools which work like the brushes in Photoshop,
except that they effect virtual shape and depth. Once mastered, you
can deposit, carve, smooth, smudge and generally shape material just
This example is by an artist from Romania, he's using an older
version of the software, but he's absolutely great with it. If you
ever seen any of his other work, you'll understand why he's
apologizing for the simplicity of the tutorial example. To download
the videos, you must first join the forum.
