We present a localized interpolation method that involves partitioning the data into arbitrary overlapping triangular regions based on arbitrary point

uction of the designed object. Apart from the design process of parametric surfaces another important domain in geometric modeling exists: shape control. In this paper we present a stability concept for surfaces based on infinitesimal bendings.

The goal is to obtain a spline that may have high second derivatives at the interpolated points and low second derivatives between two consecutive interpolated points. The solution is a .. continuous quartic spline.

A Bézier spline approximation of lower polynomial degree is built up as well, which is based on the exact trim curve representation in coordinate space.

Using the method presented herein, the user is able to create libraries of specific form features. These features can then be used in designs. Constraints between features can be set by

https://doi.org/10.1007/978-3-658-45474-6A representation of trigonometric curves and surfaces is introduced that allows intuitive control of the shape. The representation is obtained by transferring the Bernstein-Bézier representation of polynomials in geometric modeling to trigonometrically represented shapes.
