/*
plot3d - program to plot three dimensional surfaces
The CRC graphics package
Malcolm Slaney
April 12, 1982
Hacked heavily from qplot code by
Carl Crawford
Purdue University
W. Lafayette, Indiana
April 3, 1979
MODIFICATIONS:
Changed parameter code so that xcount and ycount default
to (size-begin+1)/(skip+1)...................Malcolm 8/25/82
Added Ascii Input format.....................Malcolm 11/30/82
Changed device mappings......................Malcolm 10/22/83
Added several more options and arguments when truplt was
modified and named newtru. Newtru will now draw the function
below(phi2>0) or above(phi2<0) the horizon if the x-y axes
are not drawn. For more details see newtru.f.
The new arguments are :
xdig, ydig, zdig, dig, xl, yl, zl, xlen, ylen, zlen, len,
xtic, ytic, ztic, tic, zmin, direction(=[xy]),
resolution(0.7< >4.0).
The new flags are -l and -z.
Specifying dir=y would do the job of -k flag, so later on -k
should be removed. Resolution is added to get a better
resolution in line hiding.
Mani 12/7/83
xmin, xmax, ymin, ymax and raxis parameters have been added
to the list of parameters. raxis=[xy] would specify whether
the the values for x and y axes be converted to float or not.
Mani 3/29/84
z has been added to the list of options for raxis=[xyz].
