In this work, we introduce a new type of surface called the Log Aesthetic Patch (LAP). This surface is an extension of the Coons surface patch, in which the four boundary curves are either planar or spatial Log Aesthetic Curves (LACs). To identify it

Based on quintic trigonometric Bézier like basis functions, the biquintic Bézier surfaces are modeled with four shape parameters that not only possess the key properties of the traditional Bézier surface but also have exceptional shape adjustment.

Image interpolation is important in image zooming. To improve the quality of image zooming, in this work, we proposed a class of rational quadratic trigonometric Hermite functions with two shape parameters and two classes of C 1 -continuous Coons pat

This article draws from primary historical sources to examine the origin of, and tensions between, two postwar era modeling techniques that shaped the early history of computer-aided design: the plex, developed by Douglas T. Ross, and the Coons patch

In this paper, a new parameterized surface, termed SQ-Coons surface, is proposed according to the build mode of Coons patch. The surface is always interpolated to the boundary curves, and its shape details could be controlled by the shape parameters

Given two spatial C 1 PH spline curves, aim of this paper is to study the construction of a tensor–product spline surface which has the two curves as assigned boundaries and which in addition incorporates a single family of isoparametric PH spline

On-machine inspection (OMI) systems have been widely used for the automatic setting of workpieces and the determination of the kinematic errors of a machine tool. Touch-trigger probes are commonly used in OMI systems due to their high reliability and

Surface-based models have been built to represent complex reservoir geometries. This paper presents a workflow for building surface-based reservoir models using NURBS curves, Coons patches and unstructured tetrahedral volume meshes. Surfaces are crea

In this work, we present a quadrilateral plate element for the Kirchhoff plate bending model that satisfies the continuity requirements in implicit way. The element is designed on the basis of the rational Gregory’s enhancement of the bi-cubic Coon
