WebNURBS, Non-Uniform Rational B-Splines, are mathematical representations of 3D geometry that can accurately describe any shape from a simple 2D line, circle, arc, or curve to the most complex 3D organic free-form surface or solid. Because of their flexibility and accuracy, NURBS models can be used in any process, from illustration and animation ... WebThe algorithm consists of the following steps: Initialization of the B-spline surface by using the Principal Component Analysis (PCA). This assumes that the point-cloud has two main orientations, i.e. that it is roughly planar. Refinement and fitting of the B-spline surface. Circular initialization of the B-spline curve.
