This program was written by Joseph J Charles, and provides the FORTRAN source. 1. 3-D Object plot (rotates & plots 3-D object) This displays a rotating 3D cube at about a 1 Hz rate 2. Plot Library Demo (Plots Library Routines) I haven't been able to get this to complete. It asks for the time, whether to output to a printer, how long to linger on each demo plot, and the min/max x and y coordinates for the plot, then it just sits there.
