The working principle in Rhino is somewhat different from most 3D packages and more like a CAD program. NURBS (Non-Uniform Rational B-Spline) is based on the definition of 3D surfaces with mathematical formulas (splines). Rhino gives emphasis to model’s precision and therefore uses NURBS technique. Rhino is not intended for video industry and effects where high precision is not required. Rhino is accurate as CAD, and useful when you create model for visualization and presentation, but not just for production or simulation. When I get some time, I’ll start playing with some subd modeling tools and post a real comparison, just to make it clear what I’m talking about.Rhino is the 3D-modeling software used for mathematically precise modeling of products ranging from jewelry and furniture to architecture. The problem is that the difference in workflow and necessary skills is that a lot of us have so much invested in the old, hard way of doing things. For a lot of kinds of work, history really has to go. We do have the ability to machine from point cloud data and also conversion between mesh and NURBS is becoming more readily available.Īdd to this argument the argument against history-based workflows, and you start to see some writing on the wall shaping the future of CAD and design. Subd is SOOOOO much easier for complex stuff that it really can’t be ignored. But we (engineers who design stuff to be manufactured) have avoided this type of data for a lot of reasons.
More generally, subd is so much easier than NURBS modeling especially for organic shapes. The tools aren’t really production ready, although the demos I’ve seen are a few months old already.
