[news.eclipse.gef3d] Re: Best strategy for updating all figures?

[Miles Parker <milesparker@xxxxxxxxx>]

OK, I got it running! It doesn't look that interesting, but it works. 
:) And it's fast too..much faster than draw2D rendering. I had to do a 
lot of fiddling as I expected, but as you guys advertised, the new code 
to do this is remarkably small -- I really only had to extend my 
existing 2D classes.

Any word on the other shapes you guys were working on? A sphere would 
be nice. :)  Is there a relatively easy way to get 3D models as figures?
