Hi,
This question may be strange but still i need to know...
Does GEF-->>Draw2d--->>SWT perform better graphically if the machine has a
powerfull graphics card????
In terms of rendering,zooming,scrolling....
---------------------
why, mr. Anderson, why, why do you persist?
Because I Choose To.
Regards,
Vijay

I would doubt it. Actually, this is not an GEF/Draw2D related question,
but an SWT question. Draw2D uses SWT to render the figures, thus it is
up to the SWT implementation. As far as I know, SWT does not directly
access the graphics card, so it is up to the operating system. There
was a bug report on supporting OpenGL for Draw2D
(http://bugs.eclipse.org/68724), and Kristian Duske (of the GEF3D team)
has written an OpenGL based Graphics implementation. This performs
better then the SWT based version, but it is not integrated into Draw2D
yet, and not all features of Graphics are implemented (cf.
http://bugs.eclipse.org/281360). If you are interested in improving the
performance, you may have a look at that. You will have to look into
the package "org.eclipse.draw3d.lwjgl.graphics" find in plugin
"org.eclipse.draw3d.lwjgl" .
Cheers
Jens
