@acer What you are suggesting certainly makes sense.  Putting the orientation information in the PlotComponent should be no more demanding than putting it in Maple's toolbar, as it's done currently for some of 3D plots.  I hope to see that in a Maple in the near future.

Hello Acer, thanks for your very helpful response.  It solves my immediate problem.

I attempted to extend your examples by querying indets(G,'specfunc(:-ORIENTATION)') in order to get the plot's current orientation but it just returned the empty set.  I did "lprint(G)" to see G's contents but apparently there is no orientation information in it.  Is there some other trick to extract a 3D plot's orientation information?

I know that normally one can read the orientation angles theta, phi, and psi in Maple's toolbar.  Unfortunately that toolbar is not available when Maple displays an animation.
