110325 HIDE: Hidden Line Removal/Plotting Subprogram Version: May 1977 Author: M. Oliff Submitted by: M. Vannier, University of Kentucky Medical Center, Lexington, KY Operating System: RT-11 V2C Source Language: FORTRAN/RT-11 Memory Required: 16K or more Software Required: Plotter Subroutines Hardware Required: Plotter (Pen or Electrostatic) Keywords: Plotting Abstract: A 2-dimensional plot of a 3-dimensional surface is generated using repeated calls to a FORTRAN subroutine, HIDE.FOR. Hidden portions of each subsequent curve are removed. The remainder of each curve is plotted. Axes with tick marks and labels may optionally be generated. This subroutine presently uses a Versatec D1200A electrostatic plotter or a Houston Complot DP-1 pen plotter. Virtually any pen or electrostatic plotter may be used. An example program which generates a surface plot is provided. The HIDE sub-routine is based on Williamson's algorithm.
