Discrete Rotational CMC Surfaces and the Elliptic Billiard

  • Chapter
Mathematical Visualization

Abstract

It is a well known fact that the meridian curve of a rotational constant mean curvature (cmc) surface (which determines the surface completely) can be obtained as the trace of a focal point of an ellipse or hyperbola when rolling it on a straight line. In this paper, it will be shown that discrete rotational cmc surfaces can be obtained in a similar way. In fact, the meridian polygons are closely related to the elliptic (or hyberbolic) standard billiard: the discrete analogue of the ellipse or hyperbola will be the trace of a billiard in a continuous one.
