Unless u use 1.2 version of Java3D, the only way to do it right is to
output any such strings OUTSIDE Canvas3D. The deal is that to preserve
acceptable performance in 1.1.x versions u can draw anything _only_
before or after the Canvas3D completely redraws itself (by calling
super.paint method in
Hello Doug,
thanx for the fast reply !
And yes, you are right: the best thing would be, if the translation, rotation and zoom
would work around the origin...
(Maybe with an extra "controlgroup" attached to the browserGroup ?)
Again, thanx & have a nice day

We are observing "memory leak" behavior in Java3D when we
replace one texture-mapped Image by another. That is, as we
remove one texture map from the scene graph and replace it by
another, total memory use increases with

Hi folks.
Can anyone recommend a good IDE which allows good debugging of Java 2 and
Java3D?

Thank you for helping me out :-)
I also found an other problem that made my geometry disapperar:
I have a background geometry which is a texture-mapped cube (with no top
or bottom) made using a trianglestrip with coordinates from -1 to 1 in
all directions.

Say I have a Transform3D that has some arbitrary rotation and translation.
I want to further roatate it around the stationary y-axis. Do I:
1. Make an AxisAngle object with (0,1,0,angle)
2. Make a new Transform3D and set it equal to my AxisAngle object
3. Multiply the original Transform3D object
Evan,

Jay,
Do you use multiple "Views" in the Java 3D sense? I have a strange problem
with disappearing QuadArrays when I use multiple Views (in my case 3). The
long and short of it is that the QuadArrays disappear in the 2nd and 3rd
View if the 0,0,0 point is not visible in the View.
I reported this
Bill,
Several people have reported this bug in 1.1.x. As far as I know there was
no way to work around it - hence people attempts to implement
multi-texturing in 1.1.x were stymied.
It was supposed to get fixed for 1.2, but I haven't verified it. It sounds
like the 1.2 multi-texture support, or
Janet,
...or Kawa 3.5 - which includes a JDK2 debugger (which I haven't been able
to activate yet).
I like it, as it is a very lightweight IDE that just calls down to the SUN
command line tools, so you know what it is doing, and that you can always
replace any components as soon as SUN upgrades
For my part I use Forte for Java, which is java made, and has the advantage to
be free!
But it is still in beta version, let's say with bugs. But it is ok for my use.
It also use the version of the jdk you have installed, so this is a good point
for
upgrades.
Actually, I did'nt use the debugger 'c
I don't have the answer the way you would want it but I am personally
interested if you do find the solution.

it so that it stays in the center of the screen while I look at its top,
bottom or whatever angle I prefer. I f
Hi there,
I am trying to create a MediaLocator that uses my socket to receive
compressed audio data. But it doesn't seem to work...
The audio data is compressed using a JMF processor, comnpressed to GSM (8Kz,
mono)
Can somebody help me ?
Thanks !

Hi Daniel
i will give 3.5 a try then.. :-) so far i'm running it on Windows 98 and it is
quite stable

You can try IBM Visual Age and Borland(Inprise) IDEs
On Linux all of them are free. You can get more info

Be careful mixing lightweight and heavyweight components.

Evan,
I don't understand the problem that you are describing.
... and is there any reason that you are applying rotations about each
axis sequencially? If not, then the whole idea of using axisangle is
to get a rotation about any arbitrary axis, such as [0.2, -0.4, 0.6],
that does not even have
Try the following:
call T the transform the aligns the shared edge with an axis
let R be the rotation about that axis
T^(-1) is the inverse transform that translates that face of
the box back where it belongs.
ther order of transformation is
T^(-1) ( R ( T ( box face )))
