example demonstrates the use of the mesh OOGL object. It repeatedly computes a changing function on a rectangular grid, or mesh, of (x, y) pairs. As the mesh is changed by example over time, these changes dynamically appear in the geomview window.
A second feature of example is the use of the Forms interface builder to create the user interface. This is a public domain interface builder which has been used to create geomview. It is included here because we have found it to be an effective tool for creating interactive applications. The Forms package is written by Mark Overmars of Utrecht University and is available via anonymous ftp from archive.cs.ruu.nl.
