SYNOPSIS
SEISMIC UNIX NOTES SPSPLOT - plot a triangulated sloth function s(x,z) via PostScript
spsplot <modelfile >postscriptfile [optional parameters]
Optional Parameters:
gedge=0.0 gray to draw fixed edges (in interval [0.0,1.0])
gtri=1.0 gray to draw non-fixed edges of triangles
gmin=0.0 min gray to shade triangles (in interval [0.0,1.0])
gmax=1.0 max gray to shade triangles (in interval [0.0,1.0])
sgmin=minimum s(x,z) s(x,y) corresponding to gmin
sgmax=maximum s(x,z) s(x,y) corresponding to gmax
xbox=1.5 offset in inches of left side of axes box
ybox=1.5 offset in inches of bottom side of axes box
wbox=6.0 width in inches of axes box
hbox=8.0 height in inches of axes box
xbeg=xmin value at which x axis begins
xend=xmax value at which x axis ends
dxnum=0.0 numbered tic interval on x axis (0.0 for automatic)
fxnum=xmin first numbered tic on x axis (used if dxnum not 0.0)
nxtic=1 number of tics per numbered tic on x axis
gridx=none grid lines on x axis - none, dot, dash, or solid
labelx= label on x axis
zbeg=zmin value at which z axis begins
zend=zmax value at which z axis ends
dznum=0.0 numbered tic interval on z axis (0.0 for automatic)
fznum=zmin first numbered tic on z axis (used if dynum not 0.0)
nztic=1 number of tics per numbered tic on z axis
gridz=none grid lines on z axis - none, dot, dash, or solid
labelz= label on z axis
labelfont=Helvetica font name for axes labels
labelsize=12 font size for axes labels
title= title of plot
titlefont=Helvetica-Bold font name for title
titlesize=24 font size for title
titlecolor=black color of title
axescolor=black color of axes
gridcolor=black color of grid
style=seismic normal (z axis horizontal, x axis vertical) or
seismic (z axis vertical, x axis horizontal)
Note: A value of gedge or gtri outside the interval [0.0,1.0]
results in that class of edge not being drawn.

Tweaks to improve PostScript header, add basic color support.
NOTE: Have observed errors in output when compiled with optimization
under NEXTSTEP 3.1. Caveat Emptor.
