![]() Using high-level functions, designed to provide a simple method for obtaining approximations with minimal programming,.You can program approximations in two ways: the approximation of a set of 3D points using a 3D BSpline or Bezier curve, or a BSpline surface.the interpolation of a set of 3D points using a 3D BSpline or Bezier curve, or a BSpline surface.the approximation of a set of 2D points using a 2D BSpline or Bezier curve.the interpolation of a set of 2D points using a 2D BSpline or Bezier curve.In interpolation, the process is complete when the curve or surface passes through all the points in approximation, when it is as close to these points as possible.Īpproximation of Curves and Surfaces groups together a variety of functions used in 2D and 3D geometry for: In modeling, it is often required to approximate or interpolate points into curves and surfaces. Computation of the coordinates of points on 2D and 3D curves.Conversion of curves and surfaces to BSpline curves and surfaces.Creation of shapes by interpolation and approximation. ![]() Geometry Utilities provide the following services: This manual explains how to use Modeling Data. Modeling Data supplies data structures to represent 2D and 3D geometric models.
