Hi Isaak,
I am not sure. Maybe your code did not make it to the list. So I am
forwarding your e-mail.
I did not use the PickManipulationRenderer myself, so I can't help you.

hello:
I have a little problem with the PickManipulationRendererJ3D and the range
selection, the attached code compiles and runs fine, but the only problem is
that, at run time, when i enter a range value it doesnt work as it is
supposed to.Secondly the PickManipulationRendererJ3D cannot pick any sample
when i right click.
Is it because i try to add two data references to the display ? i am
confused here. The "spikes" in the display corresponds to the ratio values
in the file flatxx.txt, so i expect that when i right click, the
PickManipulationRendererJ3D should execute the getClosedIndex()method and
pick the corresponding sample, but it is not happening. i am not sure if i
am doing something wrong since i am "new" to visad, i dont have much
experience with visad.I have spent about three days trying to find it out,
but from the top-level, i think the doAction() method in the cellImpl()
method is not working but i dont really know what i am missing in the code,
and i will be glad to know any workaround. I appreciate your time and hope
to hear from you very soon.
