Im making 3d-models for fursuits and hand puppets since 2014 and I print them on my 3d-printers (FlashForge Creator Dual, Anet A2 Plus). The grid has a rectangular topology, but of course the points may be positioned anywhere in space, to shape the curve accordingly. The left image demonstrates a surface created by revolving a 2D NURBS curve around Y axis. Nurbs calculator tutorial – 1 For introduction of nurbs calculator, please read previous post. Let me take the cubic degree of NURBS as an example to explain the usage of these equations for you, First, we normally use a, b, c, and d to represent the four control-points of cubic Bezier curve, but here in my equations I am using v0, b0, c0 and v1 to represent the four control-points of the Bezier segment-0, and v1, b1, c1 and v2 for the segment-1 and so on. Returns a nonuniform rational B-spline (NURBS). It is written in C and now there is also an editor for it. I glanced through it and understand your point now. A NURBS surface thus created will have lots of control vertices (CVs) along its geometry, which can be used to manipulate it precisely. For example, one can drill a hole in a NURBS mesh using a circular trim curve. This mesh is created using a NURBS discretization with the corresponding refinement parameter (see [17] for details. This series dives deep into curves, surfaces, keeping objects organized, efficient NURBS modeling, time-saving techniques and more. EDIT: I thought you were experimenting, but I see the code came from the OpenGL tutorial.
