I recently was pointed to this video. While it’s as much a T-Splines sales seminar as anything, it walks through some good workflow examples of how to approach organic modelling in T-Splines for jewellery design scales, not to mention showing off some lovely designs.
The video’s speaker Saskia Dattner, she a fine jeweller who produces some impressive work out of Pforzheim Germany using Rhino, KeyShot, and HDR Light Studio.
