چکیده
This paper mainly discusses the weight factor that influence on cubic NURBS interpolation curve shape. Based on the existing curve and surface interpolation, the thought, the criterion and the concrete steps of the convexity-preserving of the weight factor of cubic NURBS interpolation curve are provided, numerical examples are carried out by the computer simulation and the weights are controlled with purpose and procedure. Then a scope of the convexitypreserving is putted up with through observing the changes of the cubic NURBS interpolation curve and the associated with this operation. In addition, its application in the design of ship modeling is given.

Constrained Interpolation via Cubic Hermite Splines
Introduction In industrial designing and manufacturing, it is often required to generate a smooth function approximating a given set of data which preserves certain shape properties of the data such as positivity, monotonicity, or convexity, that is, a smooth shape preserving approximation. It is assumed here that the data is sufficiently accurate to warrant interpolation, rather than least ...
متن کاملInteractive shape preserving interpolation by curvature continuous rational cubic splines
A scheme is described for interactively modifying the shape of convexity preserving planar interpolating curves. An initial curve is obtained by patching together rational cubic and straight line segments. This scheme has, in general, geometric continuity of order 2(G continuity) and preserves the local convexity of the data. A method for interactively modifying such curves, while maintaining t...
متن کاملConvexity - Preserving Scattered Data Interpolation 33 2 . 3 Convexity Conditions
This study deals with constructing a convexity-preserving bivariate C interpolants to scattered data whenever the original data are convex. Sufficient conditions on lower bound of Bézier points are derived in order to ensure that surfaces comprising cubic Bézier triangular patches are always convex and satisfy C continuity conditions. Initial gradients at the data sites are estimated and then m...

We use bivariate C 1 cubic splines to deal with convexity preserving scattered data interpolation problem. Using a necessary and suucient condition on Bernstein-B ezier polynomials, we set the convexity preserving interpolation problem into a quadratically constraint quadratic programming problem. We show the existence of convexity preserving interpolatory surfaces under certain conditions on t...
