Hi, Long
I am currently working on the similar project.
My project is also trying to produce a robot arm simulation.
May be we can team up together and share our ideas.
I have only started learning java3d on my own. I 've found out that the
question you've asked depends on the pivot point of the rotation. I think
there is a function to set the pivot point.
Also I think there is another function that allows boolean check to see
if an object is picked up or not. Roughly If I remember right they both
should be under Transform3D class.
Sorry, I can't be much help. I am still looking for those two method
names as well.
It's possible to rotate an object manually using the keynavigator or
mouse navigator, but I think the pivot point is set as the center ofthe
object as default, to do this it must need to change a pivot point.
Hope what I talk make sense to you, because it doesn't make much sense to me.
Still, if you think we should team up together, feel free to share ideas
and method with me.
yours sincerely
Raymond Lau
