Visual tool for demonstrating surface curvature

Abstract

In this article, we demonstrate a computer tool for teaching surface curvature. Through the display of parametric derivatives, surface normals, surface curvature, and other intrinsic surface properties (such as the osculating plane), the user can explore complex surface shape using interactive graphics and advanced visualization. An illustration of the system is provided to demonstrate how the concept of surface shape can be displayed in a clear and intelligible manner. © 1997 John Wiley & Sons, Inc.
