VisAD now makes it easy to write collaborative visualization
and data analysis applications. VisAD can use Java3D or Java2D
for visualization.

The only problem with this is that you have a fixed sampling rate. You
would really like to have less sample points along the more "linear"
parts of the scene, and more sample points (and thus more polys) on
parts of the graph that change more, giving a better curve fit. In math
terms, more samp
I need to use in my programms multiple (two for

an Internet link.
Hi all,
I have a problem: I'm writing a viewer that shows machines in a canvas3d ,
now I wan't to show a back, right , left and right projection in a graphic2D
canvas , are there any methods in the J3D classes that provide this? If
anybody has done this before would you be able to share this cod
The culling is done on a per-shape basis. If any part of a Shape3D
intersects the viewing frustum, the entire shape is sent to the
graphics accelerator. As you correctly point out, this leads to a
tradeoff that has to be made: too many shapes with a small amount of
geometry can lead to inefficie
Well, looks like it's a case of broken drivers again. I started with
the TextureModeApp from the Java3D examples and changed it to play with
transparent textures and shape transparency.
If you run this, you should see a blue (0,0,1) background, with a Text2D
object (which uses transparency textu
UPDATE! On my Rage128 PRO, if I set the display properties to 24-bit,
the demo works fine. True color (32-bit) and 16-bit exhibit incorrect
transparency computation.

Lee,
Tested your test applet on a GeForce 256 system (16 bit color mode) and
your text does look "purple".
One more strike against ATI's drivers.

And to boot, I figured one more thing out. Sure, 24-bit mode works.
But it works SLOWLY! They even say in the readme that 3D acceleration
is only under 16-bit mode. This really stinks.
Does someone at Sun have a way to get ATI to fix this? I don't think I
can go to ATI with a Java3D example t
First of all, thanks to all the people from the list for their questions
and answers.
Anima3d is a simple animation studio. Anima3d allows the user to
construct articulated structures and design the scene using materials,
textures and lights. The animation is defined with a serie of keyframes.

Lee,
It may be working in 24 bit mode because ATI may not be providing any
hardware acceleration in 24 bit mode and hence Java 3D is rendering it
correctly in software. Certainly there are other cards (Voodoo) that
don't accelerate in 24 bit mode.
Good luck getting ATI to even respond to you.
There will be a moderated, online chat on the Java 3D API.
The guests are two key members of Sun's Java 3D engineering
team: Kevin Rushforth and Dan Petersen. They'll answer your
questions on Tues., Oct. 3 at 11:00 A.M. PDT. To join the chat,

Hi,
It is not enough to allocate
Point3d[] vertices = new Point3d[TOTAL_NUM_OF_VALUES];
and then invoke,
tsa.setCoordinates(0, vertices);
Use,
Point3d[] vertices = new Point3d[TOTAL_NUM_OF_VALUES];
for (int i=0; i < vertices.length; i++) {
vertice[i] = new Point3d();
}
tsa.setCoordinate
Hi Markus,
We can reproduce this problem and

Hi there!
I get the following exception. Which capability field do I have to use on the
Shap3d object to make it intersectable?
Thank you,

We are working on a distributed robot simulation system for the RoboCup
competition using (amongst other things) Java3D for rendering.
I have just read various messages on this group suggesting that where many

On the other hand, it looks purple on my Rage 128. The ATI Rage 128 drivers
seem fine. I've never gotten hardware acceleration to work at all with Rage
Pro, but I don't really care since I have one that works now ;)

Hi Kovalan,
If you want to pick using geometry (USE_GEOMETRY), you have to add the
capability Geometry.ALLOW_INTERSECT to the appropriate Geometry object (I
guess this is causing the "no capability to allow intersect" exception).
Regards,
Manu.

Just to be clear (I hate to keep adding to this thread, but here I go): I
am running an ATI Rage 128 chip on a Win98 system in 16 bit mode (with
hardware acceleration), and the demo works properly (purple text) on my
system. Of course, I am on Win98 instead of NT.
