Sean,
       Yes, please send your simple test program to [EMAIL PROTECTED]
We are happy to work with you on any Java 3D found. BTW, the following
bug was filed and fixed last week :

BugId : 4995978 - PickSegment on IndexedQuadArray returns wrong result

thanks,

I advice you to build a very simple demo with your
bug. Not reproduciple bugs are very very hard to fix
;)

QuadArrays and picking.

Anyway, now that Sun has put Java3D on hold more or
less, where can I
submit the bug (to Sun?  Somewhere else?) in such a
way that I can
reasonably expect feedback?  I ask this because
we've identified the
bug in our simulation code, but it would take a fair
chunk of time to
create a simplified example, so before doing so I'd
like to find
a venue that would have a reasonable likelihood of
being more than
just a black hole at Sun.

[For those interested: if you "bend" the quads in a
quad array at a
serious enough angle (45 degrees maybe?), then
they'll show up in the
collection of PickIntersections, and often insist on
being the
"closest" intersection, even though they are no
where even
remotely close to the pick location.  Anyone seen
this before?]
