Hi Bruce,
Since these are problems with Java3D on the Mac have you
reported them to Apple? I have reported some of these
problems myself, but I never get any response from Apple.
Do you have any control on a PowerBook over the degree
of graphics acceleration? If you do, you might consider
reducing the acceleration.

Hello All,
For starters, I use a PowerBook running OSX 10.3.9, Java
1.4.2_07 and Java3D 1.3.1 with Eclipse 3.0.1
The following seem to either not work, or cause
problems:
-
GraphicsModeControlJ3D.setSceneAntialiasingEnable(true)
Works great on XP pro but has no effect on OSX (No
exceptions)
- ToolTipManager.setLightWeightPopupEnabled(false)
Works only after making the popup visible, and then
works inconsistently (No Exceptions). Some times the
tooltips appear above the 3d canvas and sometimes below.
And they always seem to render very slowly causing one
tooltip to be carried over to another similar component.
In other words, the tooltip for component A when
rendered also becomes the tooltip that appears for
component B. I should note however that I am using an
implementation of a multiline tooltip that replaces the
default single line one.
- JPopupMenu.setLightWeightPopupEnabled(false)
For some reason on OSX it works, but on XP Pro it will
only show popups on 4 of 5 plots in the visible app
window (No Exceptions). The problem canvas gives cursor
coords allowing box zooming to function but does not
show the popup.
- Here's an oldie but a goodie....
Every once in a while I get one of 3 Exceptions listed
below. I have tried to reproduce the errors with some
consistency but cannot find the code that is
specifically causing the exception.

On more of a positive note I did get the box zooming
working like a charm and since the target platform for
my app is XP it's very nice to see the anit-aliasing
working.
Thanks,
Bruce
