A piecewise rational cubic spline [5] has been used to visualize the positive data in its natural form. The spline representation is interpolatory and applicable to the scalar valued data. The shapeâ€¦ (More)

Scientific visualization is concerned with the presentation of interactive or animated digital images to users to understand data. The advantages of scientific visualization are: huge amount of dataâ€¦ (More)

Abstract. In this paper, first free parameters are constrained in the description of rational cubic function [6] to preserve the shape of data that lies above the straight line. Then, rational cubicâ€¦ (More)

A rational cubic spline is developed to provide smooth curves(positive, monotone and convex). To control the shape of the curve, two families of parameters are introduced in its representation. Threeâ€¦ (More)

This paper deals with the shape preserving C rational cubic interpolation. The developed rational cubic interpolating function has only one free parameter. The approximation order of rational cubicâ€¦ (More)

A smooth surface interpolation scheme for positive and convex data has been developed. This scheme has been extended from the rational quadratic spline function of Sarfraz [11] to a rationalâ€¦ (More)
