On my ubuntu (7.10, maxima 5.12 I think), maxima draws using gnuplot,
and when draw surfaces with gnuplot (plot3d in maxima, splot in
gnuplot), I can rotate them using the cursor keys (up/down,
left/right) or the mouse.

The surface with colors I get using (in maxima):

plot3d(sin(x)*sin(y),[x,0,6],[y,0,6], [gnuplot_preamble, "set pm3d"]);


Is this what you're looking for?
