Hi all,
Having moved to J3D 1.3 Beta, I'm now getting an exception with
Shape3D.intersect(SceneGraphPath path, PickShape pickShape) that I
didn't seem to get before.
I first do a Locale.pickClosest() with a pickSegment to locate
a Shape3D and then do a Shape3D.intersect(SceneGraphPath path, PickShape pickShape)
with the returned Shape3D/SceneGraphPath and the same PickSegment.
This second call NPEs, but apparently only when geometry concerned is a QuadArray.
My other geometries all seem to be passing this test OK, and I have the same
capability bits set for each.
Has anyone seen anything like this ? I think it's going to take some time
to generate a standalone testcase, so I'd welcome any feedback before I
embark on this.
Thanks
Rob (Sample exception follows)
