Hi,
I don't think it's that expensive and anyway you are only using one node. Put
it the background node and then see how costly it is.

Why don't you pass command line parameters in the main method when running
the applet as an application(which is what the main method is for) and use
the init getparameters for when running in browser ?

The problem is that I cannot get the parameter values in the main() method, and I need
the values here, because
new MainFrame(new HelloUniverse(), 100, 100) is called from main(), which is
executed before init().
Should I have to run the applet without using the MainFrame class ?
Many thanks
Kyle,
I'm experiencing the same things, only I have an ordinary JTextArea in the scroll pane
(which floats above my Canvas3D). I think this is being caused by the Canvas3D, but
I'm not sure why. Maybe a light/heavyweight problem?
I'm using WinNt4, JDK1.3.0, J3D1.2.1 OpenGL.

The main method is called when you run the applet as an application from the
command line. It doesn't even know about the html with the parameter values.
Look at the SphereMotion example on how to get values from the command line
into the mai method.

Another case of weak documentation, (setMinimumFrameCycleTime) "will
ensure that the time between the start of each successive frame is at
LEAST the specified number of milliseconds" ie this will introduce a

No, the Java 3D API method View.setMinimumFrameCycleTime limits the
*maximum* frame rate. Remember that frame rate and frame time are the
inverse of one another.

Josh,
You may be right in your case. It probably is a light vs. heavy thing.
But in my case, I'm using the AWT scrollpane, just for that very
reason - It's also Heavyweight, so there shouldn't be any issues.
I think it's some sort of problem in the uncover/repaint code.
But I don't even know w
This was put in at the direct request of application developers who
were complaining that their scenes were running at greater than 100
frames per second and chewing up all of the CPU time needlessly. The

An applet has four important methods, init(),start(),stop(), and destroy().
These methods are *called* by the browser the applet is embedded in. The
browser *never* calls the main() method.
If you are running the applet from a browser or the appletviewer, use the
init() method to create the MainFr
Thanks for the clarification Kevin, that makes good sense. For our
projects, performance concerns are reasonably handled by scheduling our
work inside behaviors that wake up every so often (typically 20 times
per second). Our GUI has remained responsive and the frame rate is
often over 100 fps.

Whoah, where did you learn *that*? That is very odd. I would *never*
have come up with that on my own given 20 years, 200 margaritas, and
2000 java books. I may give that a try. Looks *way* too simple. ;)

What you are doing sounds like it should work. I have attached
a modified AppearanceMixed that uses setModelTransform(). It isn't
doing what you need it to do, but it gives you an example of
using it.

Yep, I think I finally got it. I just had some problems computing the
total xform above the shape. Now I think my problem is lighting... none
of the objects are lit. How do I do the lighting?? I want these
objects to be lit just as if they were still in the scene.

transform the light parameters. Region of influence and scoping are

What exactly should I do to update image on Raster ?
1) Should I set it's ImageComponent2D to null and back to same IC after
update ?
2) Should I reuse same ImageComponent2D, use two (kind of double buffer)
or create new one every time ?
3) In case of byref image, can I update it on just after de
David, do you still use serialisation? Do you agree it is also too slow (apart from
buggy)?

Hi,
I believe that Scenegraph serialization will be optimized in the next
releases of Java3D. Remember that the Fly through demo is only beta.
Everyone needs a reliable efficient network transport of 3D objects.
I belive people at Sun are making big efforts on their side.
Nevertheless Justin stat
Hi Silvere,
The SceneGraph IO API in Java3D Fly Through does NOT use java.io.serialization,
it stores the data in it's own binary format which is designed for fast
loading of scene graphs. The API supports IO to disk (using RandomAccessFile)
and IO over a network (using Streams).

John,
BranchGroup does create some duplicated data, and the amount of memory
varys depending on what is above and below the BranchGroup. The memory may
increase significantly with the number of heavy weight nodes in it path, such
