As a very new (< 1 week) VisAD user, I've got a few questions that I'm
having trouble finding answers to:
1) Using PickManipulationRendererJ3D, I'd like to be able to have some
way of telling what I've picked. Currently, I'm doing this by having a
separate field and DataReferenceImpl for each thing that I might want
to pick, and passing the Java object in to an appropriately designed
subclass of CellImpl. Since there's a separate CellImpl for each
object, I can then tell which object i've clicked on.
This works, but seems a bit clunky. Is there a cleaner way to do it?
2) Having clicked on something, I'd like to remap its appearance, which
is currently determined by a reference to a ConstantMap which defines
colors and point sizes. What's the best way to go about redefining the
constant map?
3) How would I go about changing the initial view (zoom and camera
position) of a DisplayImplJ3D?
4) I'd like to revise the rotation behavior for the DisplayImpleJ3D.
Specifically, I'd like to support (at the user's discretion) rotation
that is constrained along one axis at a time. What would be the best
way to do this?
Any feedback would be appreciated. I realize that some of these issues
have been discussed on this list at various times, but I was not able
to find answers that seemed to fit these questions.
thanks,
Harry
