Web4.2 B-spline Curves The word spline comes from the loftman’s spline, which is a long, narrow strip of wood used to fit curves passing through a specified series of points. Mathematical B-splines were first used bySchoenberg for statistical data smoothing [Fari97]. The original description of B-spline curves made use of divided differences and ... 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.

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. WebThe spline curve and its derivatives are defined in the following illustration for a cubic spline segment. Figure Spline There are many different types of spline curves. The ones used in NX are Non-Uniform Rational B-spline curves, sometimes referred to as "NURB" curves. A Bezier curve is a B-spline curve that consists of only a single segment.

WebIn general, editing a spline with control vertices provides finer control over reshaping a small section of the curve than editing a spline with fit points. You can insert additional control vertices to a section of a spline to obtain greater control in that section at the expense of making the shape of the spline more complicated.
