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. Figure 1.13 illustrates a single insertion of a knot at … 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.
