NURBS, the parametric representation of curvy geometry, is at the core of Rhino's capabilities. Likewise, some of the most powerful features of Grasshopper leverage Rhino's NURBS tools. This video creates 1-degree surfaces and talk about why they are discouraged generally in Rhino, what they are good for, and how you can work with them in Grasshopper.
- [Narrator] I have my exercise file open already. … In this video, I want to talk about one-degree surfaces. … One-degree surfaces are discouraged … by the modeling process in Rhino and Grasshopper, … and typically, if you do operations … that would otherwise result in one-degree surfaces, … they're converted automatically into polysurfaces. … So if I bake this curve, … it's a polyline, … which is actually a one-degree NURBS curve. … So it's one degree because the curve … actually touches each of its control points. … But if I bake the resulting extruded surface, … I can see just by looking at it … the parametrization of each of these faces … on the surface are distinct … and if I explode, … I have a bunch of individual surfaces … so I create a polysurface. … And this is great most of the time … when you're modeling in Rhino. … This is what you want to have. … But if you're using the parametrization of the surface … to do stuff in Grasshopper, … you want to preserve that continuous parametrization …
