I was looking at http://dynamicnetservices.com/~will/gnuplot/
<http://dynamicnetservices.com/%7Ewill/gnuplot/> which attempted to plot
3D images using gnuplot. Im trying to plot 3D images too but they're
more of objects rather than shapes. I was wondering how do you plot
hemispheres or half hemispheres. What Im really attempting to plot is an
image which looks something like
<http://www.resa.net/nasa/images/io/io%20core.JPG> using gnuplot.
Thanks for your help.
