This webinar was streamed on October 23, 2019. I presented present a number of real-world 3D modeling applications, including concept models and complex 3D patterns, showing different modeling techniques that use NURBS, Meshes (subdivision surfaces) and the new SubD geometries.
My goal was to demonstrate some of the 3D capabilities of Grasshopper as well as to explain the main differences between NURBS and meshes and when to choose one approach over the other.
Above: it is possible to combine a pattern made with SubD geometry with a pure NURBS surface
I also made an introduction on how to combine the best of both worlds with a hybrid modeling technique that uses the new SubD geometry featured in Rhino 6 for Windows and Mac and 7.
