WebRefinement is usually advocated as a means of gaining finer control over a spline curve or surface during editing. For curves, refinement is a local process. It permits the change of control vertices and subsequent editing of the detail in one region of the curve while leaving control vertices in other regions unaffected. WebA B-spline curve is continuous in the interior of a span. Within exact arithmetic, inserting a knot does not change the curve, so it does not change the continuity. However, if any of the control points are moved after knot insertion, the continuity at the knot will become , where is the multiplicity of the knot.

WebMar 9, 2024 · 4.41 Interpolated Spline. An interpolated spline curve passes through all the points used to define the curve. Other spline curves are approximated: they are defined by a set of vertices. The resulting curve does not pass through all the vertices. Instead, the vertices “pull” the curve in the direction of the vertex. 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.
