If you need a plotting program for the linux console or an example
of a plotting driver you can try the pm3d branch of gnuplot. You've
to get the latest version via cvs from sourceforge:
see:
http://sourceforge.net/cvs/?group_id=2055
basically it's:
cvs -d:pserver:anonymous@cvs.gnuplot.sourceforge.net:/cvsroot/gnuplot login
cvs -d:pserver:anonymous@cvs.gnuplot.sourceforge.net:/cvsroot/gnuplot co -r pm3d gnuplot
all terminal specific stuff is in the file term/vgagl.c
for building the linux console driver (including colored surfaces and mouse
support) you need libvga, libvgagl, and the threedkit stuff which comes also
with the svgalib source. I've packed the latter to a separate lib which can
be obtained at
http://www.zellner.org/gnuplot/
(lib3dkit-1.4.tar.gz)
for examples you can view the two vgagl*.png's at the same site.
3d-Plots like in these examples can be rotated by dragging with the mouse
at a speed of several frames per second. You've to try this. It's incredible!
good luck!
