A slight correction...
There was a bug in the code I proposed. The line
bits = (bits << 8) | getByte();
(or arr[i] instead of 'getByte()', it is the same except for byte order)
should be replaced by:
bits = (bits << 8) | (((long) getByte()) & 0xFF);
Rational: 'byte' and 'long' are signed in
I have tested it passing the file as an URL like this:
VrmlLoader loader = new VrmlLoader();
URL fileURL = getClass().getResource("test.wrl");
Scene s = loader.load(fileURL);
and it works.
Hope this helps !!

Hi,guys and gals,
Hi,
I have problems with making the objects I make "come out of the screen" when
I work in stereo. I can se them disappearing in the back of the screen, but
they will not come out. Is there any parameteres I have to set to achieve
this effect?

Hi all, hoping for help as well ;)
My problem is the following:

Without transparency, everything works well.

I'm not sure if this has been answered yet, but what works for me is
to load objects from a file, and descend the branchgroup to the
Shape3D objects and use
getAppearance().setTransparencyAttributes(...)
If you're object consists of multiple shapes each one must be altered
to become transparent.

this would mean system.currenttimemillis is using windows timers, the
worst choice available on windows.
a better choice would be the multimedia timers.
perhaps the right folk could be pointed out, so this could be addressed?

Java 3D does state sorting of this kind as well. And, either case below
will work equally well. You will, however, get other performance benefits
from using fewer Shape3D nodes.
