Dear All,
I am trying to load x3d file using LoaderDemo which
comes with Xj3D, it works fine when run it as a
standalone program, I just replaced VRML97Loader with
X3DLoader. But when I modified it to a class extending
JPanel(instead of JFrame)and tried to use it in my
swing client- a j2ee client,
Hi Dirk,
I have tried the codes, and it works well for
perspective projection. Is there any chance that this method works for parallel
projection as well?

Hi All,
Now I'm changing the appearance of an object & enabling lights

I believe that the Quad Buffer option needs to be enabled within the OpenGL
panel of the Display Settings control. The machine isn't available to me
now so I can't double check this.

I'm not a Linux guru but I'd probably try something roughly the same.
Make a shell script to execute the app (with everything properly
exported) and let Java call that shell script from rt.exec().

If we are talking about such number of symbols, I think you should think
about particle system. Use single quad array for all labels, on each
viewplatform move aligning it perpendicular to view. You have two

Hi Mian,
I put a Canvas3D in a JPanel, and put that wherever it is needed.
Easy. I basically did what they do in LoaderDemo. I could dig out some
code if you want it.

Jack,
Is "/home/jsg3/app" an executable shell script? (did you give it execute
permissions?) Or is it the C++ program itself? Does it run from a
Linux command prompt?

I think you started in the wrong direction. You want to say that you have 1

I was also thinking of using LineStripArrays

face 50 and edge 50 would have the same geometry.
But then, would 8000 shape nodes with linestrip
geometry be more/less efficient than using 8000
