3DSHADE uses shading rather than a wire frame to plot z=f(x,y) in
three dimensions. It requires a VGA graphics board and a VGA monitor.
For the function supplied, try -1<=x<=1, -1<=y<=1, 70 divisions for x
and y, and 30 degrees for tilt and rotation. To plot another function,
change f(x,y) in the Microsoft C source, recompile, and run.
