A pentagonal surface patch for computer aided geometric design
A vector valued interpolation scheme for a pentagon is described which is compatible with surface patches which have a rectangular domain of definition. Such a scheme could be useful in computeraided geometric design problems, where a pentagonal patch occurs within a rectangular patch framework.
متن کاملSurface Interrogation in Computer Aided Geometric Design
Geometric modelling of vehicle bodies like cars, airplanes, ships etc. uses the geometric concepts of freeform spline curves and surfaces.The quality of these models can be analysed with several surface interrogation tools like curvature plots, isophotes, highlight and reflection lines. In this paper several approaches to reflection lines are reviewed. The main aim of the paper is to reveal the...
متن کاملComputer-aided Geometric Design Techniques for Surface Grid Generation
This chapter focuses on three computer-aided geometric design (CAGD) techniques that are often needed to \prepare" a complex geometry for grid generation. Standard grid generation methods, as discussed in [George '91], [Knupp & Steinberg '93], and [Thompson et al. '85], assume that parametric surfaces are well parametrized and free of undesired discontinuities. We describe CAGD techniques that ...
متن کاملClassifications and Properties of Materials for Chairside Computer-Aided Design/Computer-Aided Manufacturing Dentistry: A Review
Background and Aim: Chairside computer-aided design/computer-aided manufacturing (CAD/CAM) systems have become considerably more accurate, reliable, efficient, fast, and prevalent since 1985 when CEREC was introduced. The inceptive restorative material option for chairside CAD/CAM restorations was limited to ceramic blocks. Today, restorative material options have been multiplied and include me...
