Re: [visad] Display bug found in VisAD: Geometry Disappears


Thanks for your very clear statement of the problem.
I no longer work on VisAD, but one part of your message
caught my eye:

If this bug proves to be difficult to track down, or is even
a bug in Java3D, one work around would be, whenever data
is added to or removed from a display, to trigger a delayed
(say, after 0.5 second) redraw. My memory of Java3D is a
bit shaky, but this might be done by setting the
projection matrix (to the same value it currently has).

Good luck,
