Leveraging NURBS: One-degree surfaces

“

- [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 so you can sample all the way…
