The following code sample illustrates how to get and modify the tangent vector of a spline at a specific FitPoint. In this sample: 1. User should firstly select a spline's FitPoint through UI 2. Use ...

Abstract: In this paper, we proposed a nonlinear subdivision scheme based on tangent vector, with the purpose of offsetting the deficiencies of Dyn's 4-point method and other classical linear ...

Abstract: Characteristic curves of vector fields include stream, path, and streak lines. Stream and path lines can be obtained by a simple vector field integration of an autonomous ODE system, i.e., ...

Say you have a set of data points to which you would like to fit cubic Bézier curves in a piecewise fashion. There's a nice solution dating from 1995, complete with MATLAB code, that does this with G1 ...

The tangent is defined as the single point where a straight line meets a curved surface. The tangent can be determined with a collection of mathematical formulas but is most commonly determined by ...
