oplot

Oplot is 3 dimensional object plotting program, giving the user full control over the viewing parameters. Oplot reads a description of the objects to be plotted on standard input, and produces a PostScript file on standard output. In particular, oplot will convert an plot output file from O to POSTSCRIPT format. However, the program is not specifically intended for O, but is generally applicable. Command line options are

-z Set depth cueing on, so that lines closer to the viewer are drawn with thicker lines.

-f Draw a frame around the picture

-v Verbose mode. Output some information on the creation of objects. Much more than you need. Probably only useful for debugging.

-r Print the revision level of the program, and exit.

-g GhostScript mode. Make a black background in the viewport, assuming the output plot is in colour, and will be viewed with ghostscript or some other previewer.

-b Black and white mode. All colour settings are ignored, and everything is drawn with black.

If an input file name is given, oplot will read from that file, instead of standard input.

 
oplot < mola.plt > mola.ps

oplot -f  mola.plt > tmp ; gs tmp
