Hi James,

Yes, I'd like to see your code if you would be kind enought to email it
to me.  Thanks.

As far as I can tell (and I'm so _not_ an expert at this) - you can't.
Although you can get a Graphics2D object from a Canvas3D and draw on
that, it absolutely kills performance.

The j3d.org packages include examples of overlay classes, which kind-of
allow you to fake it.  What these do is however a mere convenience: they
just insert the relevant 2d objects in the 3d universe at a z=0 position
 for your viewpoint.

I ended up doing this myself manually:  I used the LocalToWindow class
(found on Sun's java3d-interest mailinglist archives) which translates
local 3d coords to window coords, and wrote an inverse function.  But
that may not be appropriate in your application. (Mail me offlist for
the code if you want).

I look forward to being contradicted!

James.

What is the best way to write static 2D data to a Canvas3D?  For
example, if I wanted to draw a title centered at the top of my screen
(which would be positioned relative to the dimensions of it's AWT
container rather than scene geometry), what would be the best way to do
this?  Reading through the docs has left me confused as to the best way
to do this.
