![]() ![]() The video starts by examining SubD surfaces and how these compare to NURBS before moving on to look at some examples of how and why SubD can be used alongside the traditional NURBS workflow in Rhino. ![]() Similarly the Control Point Curve and Interpolated Curve have ‘SubD Friendly’ options that allow accurate SubD surfaces to be produced from a curve layout in a similar method that one might employ for NURBS modelling but with the advantage of the inherent smoothness of SubD surfaces. As far as I know, all three are based on the Catmull Clark subdivision system, so the sub-d smoothing part should similar, except T-splines treats star points, and triangles a little different than the other. We learn how to navigate the Sub D interface. I’ve played more with Rhino and Clayoo sub-d conversion than T-Splines or Fusion, but here’s my take on the differences. Rhino can create, edit, analyze, document, render, animate, and translate NURBS curves, surfaces and solids, subdivision geometry (SubD), point clouds, and. Whilst traditional SubD ‘push-pull’ editing of edges, faces and vertices is enabled, Rhino’s surface commands such as Loft, Revolve, Sweep 1 & 2 and Extrude all now produce direct SubD output. In this tutorial we're going to take a first look at the new Sub D tools available in Rhino 7. Rhino SubD objects are, however, high precision spline based surfaces and thus introduce a level of accuracy to the process of creating complex freeform shapes. ![]() Location Turns mesh vertices into SubD surface points (right). “ Traditionally SubD objects are mesh based and lend themselves well to more approximate types of modelling such as character modelling and creating smooth organic forms that are controlled in an approximate fashion. Command-line options UseMesh ControlPoints Turns mesh vertices into SubD control points (left). ![]()
