Abstract

Algebraic surfaces, defined as the zero set of a polynomial function in three variables, present particular problem for visualizing, especially if the surface contains singularities. Most algorithms for constructing a polygonization of the surface will miss the singular points. We present an algorithm for polygonizing such surfaces which attempts to get accurate representations of the singular points. A client-server approach, with a java applet and a C program as backend, is used to enable the visualization of the polygonal mesh in a web browser. This system allows algebraic surfaces to be viewed in any web browser on any platform.
