I'm trying to use the PickingLibrary. I haven't explicitly set any Bounds on any of my objects. When I pick I get the following error:
Code:
Exception in thread "Render Thread" java.lang.NullPointerException
at org.xith3d.picking.PickingLibrary.getPickCandidates(PickingLibrary.java:118)
at org.xith3d.picking.PickingLibrary.pickNearest(PickingLibrary.java:395)
at org.xith3d.picking.PickingLibrary.pickNearest(PickingLibrary.java:424)
at org.xith3d.picking.PickingLibrary.pickNearest(PickingLibrary.java:450)

Anyone have any ideas?

Also once I get this working will I have to set the bounds for my objects, or will it calculate them automatically from geometries?

I will have a look at this NullPointerException this evening.

The Bounds are always autocomputed by default.

Hey Marvin, I was wondering if you looked at this yet.

Just for the record, I found the cause of this problem in my own code.

Oh, cool Smiley.

Wow I just forgot this issue. Sorry. But I have had my hands on the Bounds managing code the last days. Should be everything alright.
