ahoy all..
maybe im missing something basic, but why does Locale have a
Locale.removeBranchGroup(BranchGroup bg) method but Group doesn't have
Group.removeChild(Node n) which allows you to remove a child without
knowing its index in the Group? now when i want to remove a child of a
group, i have

I hesitate to post this because it's such a hack, but it
does demonstrate lighting lines.

In my application, I need to create and delete objects fairly often. I create the
objects as a BranchGroup, and when I want to delete them, I use the detach() function.
Everything seems to work, but memory consumption continues to ramp and performance
gets increasingly slow. Is there something

Try making the lines anti-aliased and give the glowy lines brighter colors than
the dim lines. This may give you the effect you are
Hmm, lots of great discussion on whether or not Java3D cuts the cake. I thought
I would add in some of my own info here as well.
Performance:
Yes, Java3D can be slow for some things, if you do a brute force
approach. If you have spent time building games and visualizations with OpenGL,

In its current form, I would say 'no'.
This is one particular beef that I have with Java3D. Why is it so slow, and
why does it balloon up in size as more items are added to the scene
Hi there!
It is possible to set the parameter of the View-Object so that the geometric objects
in the stereo mode seem to be before the screen and not in the monitor.
Thanks,

Well, the bottom line is that in order to use multiple Interpolators on
one object, you need to use multiple transform groups. It looks like you
can do this to the ViewingPlatform by using the method
"getMultiTransformGroup". Then you can get one of the transform groups to
connect to. As for do

Ok, let's bet on whether or not this will change. A sixpack, anyone? ;)

Hi all,
we have developed a double cell robot simulation system called Bart+Rosie.
Try it out:

Download the system, unzip it, start Setup.bat, then start br-start.bat.
Up to now it does not do a lot. you can instruct the robots u

I don't think I know what this "MultiTransformGroup" is. Can't find it in
the API Documentation either... What is it?
Andrew,
I have recently subscribed to the list as I am hoping to produce an editor

Justin and everyone,
I don't think the problem is restricted to applets, distributing
applications over the web is not very practical either.
Say, for instance, I have a shareware application, which I want people to
try via the web. If I were to use C++ or visual basic, I could create a
