Re: [JAVA3D] Trouble with pick reporting (bug?)

[J. Lee Dixon]

After a little investigation, I have another set of code that shows
REPEATABLE results with my pick reporting problem.  I now have 5 boxes
and 4 cones:
  box1: red cone
  box2: blue cone
  box3: green cone
  box4: gray cone
  box5: empty

Shift all the cones up one box by first selecting the gray cone, then
selecting box 5.  Continue with the green, blue, and red cone until the
scene looks like:
  box1: empty
  box2: red cone
  box3: blue cone
  box4: green cone
  box5: gray cone

Now, try to select the green cone in box 4.  I've tried it on two NT
machines now with the same result of not being able to select the cone.
The other cones still work.

Anybody else get the same results as me?

I have an example application I wrote to help me investigate problem I
was having with pick reporting.  This application has 3 boxes that act
as slots to receive cones.  The user clicks on a cone, the cone
disappears to denote being "held", then a box is selected to place the
cone in front of the box.

The app works well most of the time.  Every so often (often enough that
to me something is broken), the selection routines ( specifically
PickCanvas.pickClosest(), which returns a PickResult, and
PickResult.pickClosest() ) will not return the closer item, which is the
cone, but return the box behind it.  Seems to me that the sorting of
picked items randomly goes bad.

Can someone (SUN?) give this program a try?  You have to spend a little
time picking the cones and moving them around, but every so often, a
cone will get stuck and the selection routines won't allow picking it.
