Hi all,
I want to create a class (I will call it Tube)
that will represent a cylinder with inner and outer radio, lenght and an angle
refered to its axial axis that represent a section of the Tube (this data will
be read from a Database) . The classes that I had created before were
always ma
Hi Robert,
Look into \demo\java3d\GearTest. There is a source file
called Shaft.java. It generates indeed a shaft, so a cylinder
and top and bottom face. But, I'm sure you will be able to
modify the code to the tube you want.

Hi,
What is the best choice to draw buttons
in a 3D scene?
Java3D have built-in support to draw our
own buttons?
Thanks in advance

Hi Java 3D fans
I do a simulation. The calculation takes about a second and the rendering
about 0.5 to 10 seconds. that is how it is done in a Thread so far:
in Thread.run():
canvas.stopRenderer();
heavyCalculation();
canvas.startRenderer();
//wait
try {
Thread.yield();
Thread.sleep(500
Hi
Look at the WakeupOnElapsedFrames behavior, it's easy to put one in your
scene and the call the heavyCalculation from there.
Cheers
Jeremy

Should be able to do it by subclassing Canvas3D and overriding the
postSwap() method:
public class myCanvas extends Canvas3D
{
public Object waitObject = new Object();
public void postSwap()
{
waitObject.notifyAll();
}
}
Then instead of Thread.yield() etc. just call myCa

What a pity that Sun didn't anticipate that people may wish to extend

You will need to reference it in your applet tag in the html, but apart
from that, I think that will be enough.

Looks like you're seeing that pixilating problem which occurs when
your textured shape is farther away. If that is the case, you may use
MIMMAP mode, however, you have to be prepared to create more

one being 32 by 32 pix
