any idea if there is any examples or any leads ?
Thanks in advance

Hi,
I am really interested to get rotation tool in the next version of GEF...
Anyway is it possible to get your code to already use this feature in my
project ?
thanks,
Matthieu

Hi,
in the context of GEF3D, we have to support rotation as well. That is,
our 3D figures support rotation. But IMHO it is almost impossible to
support rotation in GEF without compatibility problems.
We have decided to rotate figures about their center point, which is
the standard in 3D applications. Since the location of a figure is the
top-left corner of a figure's bound, a rotation may move that point.
How do you handle that problem? For example, w/o rotation, the
following test will succeed:
figure.setBounds(b);
r = figure.getBounds();
assertEquals(r, b);
Does this test succeed with rotation?
We , that is Kristian, is working on that problem at the moment, and it
would be nice to get your opinion in order to make GEF3D compatible
with future GEF versions.
