WebSep 1, 2016 · Due to the establishment of terrestrial laser scanner, the analysis strategies in engineering geodesy change from pointwise approaches to areal ones. These areal analysis strategies are commonly built on the modelling of the acquired point clouds. Freeform curves and surfaces like B-spline curves/surfaces are one possible approach to obtain … 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.
