This is an evaluation version of RAYTRACE.

Raytrace is a program written specifically for the purposes of
teaching and exploring geometrical optics. It allows the user to:
   * trace rays through arbitrary 2D optical systems
   * animate and drag the diagrams with the mouse
   * demonstrate dispersion with different coloured rays
   * demonstrate all the ray diagrams you need in a
     course on geometrical optics.

A review of the program is due out in "Computers in Physics"
in Sept/Oct 1995.

A quick tour of many of the features is available when the
program is run.

The evaluation copy of Raytrace is freeware - you may copy and
