Daniel,
I've had the same problem for quite some time. When I rotate a scene such
that 0,0,0 is outside the field of view, the object disappears. Rotating
the scene, translating backwards, increasing field of view will make it
reappear, but only because it moves the origin back inside the field of
view. This all happens within a single view, so I don't think our problem
lies in multiple views. I would not be surprised at all, however to see
that it lies in the use of TransparencyAttributes. My problem didn't exist
until I added Transparency.
I posted a couple of mails about the disappearing object some time back,
but with no answer from the Sun people. I believe others have noticed this
problem also (David Halle had problems with terrain visibility).
I believe it is time for the Sun people to investigate this further.
Cheers,
B.

Subject: [JAVA3D] All QuadArrays disappear [Update 1]
All,
Things just got even stranger! I modified the initial size of the Frame
from:
new MainFrame( new PlatformTest(), m_kWidth, m_kHeight );
to
new MainFrame( new PlatformTest(), (int) (m_kWidth * 3.5), (int) (m_kHeight
* 1.1) );
Where:
static final int m_kWidth = 256;
static final int m_kHeight = 256;
[Yes, this really was the *ONLY* change].
Now the QuadArray tiles do not disappear when 0,0,0 is not in view but
flash ON and OFF horribly instead! I'm starting to doubt my sanity... What
on earth has the initial Frame size got to do with anything!!
Sincerely,
Daniel Selman
