WebSpline Curve Clay. geometry node. Deforms a spline surface by reshaping a curve on the surface. The Curve Clay op is similar to the Clay SOP in that you deform a spline surface not by modifying the CVs but by directly manipulating the surface. However, instead of using a point on the surface, you use one or more faces to deform that surface. WebJul 1, 2007 · Based on smoothing spline curves with some constraints, this approach achieves cam profiles that satisfy requirements in displacement, velocity and acceleration curves. Apart from the smoothness, which is the implicit essence of the proposed method, our method can also strictly constrain the shape of displacement, velocity and …
