Hello Forum,
When I change the frontClipDistance of the View then Some part of the
structure is clipped.
If I start picking a point then the clipped point of the structure is
selected.
Is there any way out not to select the clipped structure?.

Have you set the capability ENABLE_PICK_REPORTING for the TGs? If not, you
won't get them.

Mike,
Not sure but I think you have to call
setCapability(Node.ENABLE_PICK_REPORTING) on your transform groups. This
will cause them to appear in the SceneGraphPath returned from the picking
operation. Afterwards, the getNode should work.

Are you the guy from Wayne State? I knew there is a guy who was in the CS dept before.
Happy to know you are using Java3D too.
I think when you pick a point from the point array, it will get the GeometryArry from
the PickIntersection, so this array will contain all the points, but you can find
Hi, all
I just have a picking problem which I can not find any clue, any suggestion
or solution will be very helpfull.
I use the PointArray to create a lot of Point Objects in the scene, then
I try to Multiple Points using the PickCanvas's pickAll() funciton.

You should be able
Thanks Kelvin.
Is there any way around the shared group limitation?

Two problems I am running into:
1. Java3d is not letting me pick against an object in a shared group. This
is a big problem for us since a lot of our stuff like rocks, trees, etc are
in Links to shared groups. I can't understand why this is a limitation.
2. I am getting the error "interp point
Apologies as I am reposting this message with
the correct subject line.
I have implemented a utility for picking
points on the surface of a mesh. Once a point
has been placed it can be dragged over the
surface until it is in the correct location.
This works fine 99% of the time but occasionally
I found it : ALLOW_FORMAT_READ

Hi all,
I've a problem with picking objects.
I've done for all the nodes : setPickable(true).
and I've done for some nodes : setCapability(ENABLE_PICK_REPORTING)
I have a PickCanvas with mode : PickTool.GEOMETRY
When I get a pickResult with PickResult.pickClosest() we always get the
same result.

I don't have a ready-made example, but this should be simple using the J3D 1.2
