Well, seems to be time for Rudy and James to step in. <grin>
No, to be serious: I understand that you refer to the figure at the
beginning of the Henon description in James' book. (I have the german
translation, so pagenumbers are of little use.) There you have a three
dimensional curve which is cut at a specific plane, specified by an angle A
in the XY plane. It might be useful to have this 3D curve presented on the
screen, but it will be very crowded. It'll be very time consuming, too,
because you'll have to calculate x' (which is the distance in the XY plane)
and y' (which is the Z value) for every angle A running from 0 to 2*pi.
Then you want to place the cutting plane interactively by rotating the plane
around the Z axis. As a graphical aid this might help. I don't know. In fact
you can do what you want right now by changig the B (Chaoticy) parameter in
the Henon dialogue box. Since A is B*(pi/4), you'll rotate the cutting plane
to the angle A of interest.
I hope this is correct and I would be glad if someone (Rudy?) could confirm
it.
