Hi all,
I'm currently trying to add collision detection to my Java3D project, a
little Lego editor. When the user picks a 'brick' to move, I add a behavior
with a WakeupOnCollision tied to the brick's branch group. As soon as I do
this I get the exception below.
Can anyone shed any light on wh
That's my problem.
I want to rotate my 3D model using a RotationInterpolator.
It works fine, but while it's working, the CPU usage is 100%.
This is my interpolator code:
RotationInterpolator rotator =
new RotationInterpolator(
new Alpha(-1, time),
rotationTG,
yAxis,
0.0f,
When generating a 3D box, build with floor, walls and a ceiling i get
sometimes the following error:
java.lang.ArrayIndexOutOfBoundsException
at com.sun.j3d.utils.geometry.Desperate.foundSplit(Desperate.java:316)
at com.sun.j3d.utils.geometry.Desperate.existsSplit(Desperate.java:2
Thanks very much Paul.
A description which actually relates to what a singular matrix does! Perfect,
just what I needed. I think I've solved the problem now.

Hi.
Cd. anyone advise about (1) locating the java3d library for a Mac
and (2) using the 3d libraries with CodeWarrior on the Mac? Wd.
appreciate any guidance. Thanks.

Hi Kevin,
Using your loader my program compiles, but when I run
the program I get the following error:

Hi all,
In trying to implement simple collision detection, I've hit a problem with the
WakeupOnCollision behaviors. I'm using J3D 1.3b1 and JDK 1.4.
1) Even though I specify WakeupOnCollisionXxxx.USE_GEOMETRY, the collision
behavior triggers whilst the objects are some distance apart. But prob
Is there a way to determine or decide when a scene
gets rendered? If I transform say three things is
there a chance that the scene will get be drawn in the
middle of that, and how do I deal with it? Is there a
way to be sure you draw to some buffer and then swap
it in when all changes have been ma

No. The conceptual model of Java3D is there are two threads. One thread

Your problems are basic classpath issues. You will either have to
explicitly define the classpath with the -classpath parameter, or you will
want to use the Class-Path parameter in your own jar file.
I can help you get this working, but I don't think it's something we need to
discuss on the list
Does anyone have a suggestion/tool for tracking down "memory leaks".
I build a BracnkGroup with lots of objects. Attach it to my scene. Later,
I detach it. After detaching and calling System.gc(), I *never* see the

JProbe is much better than OptimizeIt, but also a lot more expensive.

Alright... Just how hard did you guys work to make the name
for that editor work out like that? :)

I am interested too!
I want to encourage Sun (and Apple) to get this done ... it would be
good for both company as we can run our software on ALL our platforms ... I hate
to see either Java 3D or Macs go away

I have the following lines in my code:
System.out.println("Before:i:j:X: "+i+":"+j+":"+hldx);
//thePoints[0][j] = new Vector3f(hldx, thePoints[0][j].y, hldz);
System.out.println("After:i:j:X: "+i+":"+j+":"+hldx);
Which prints:
Before:i:j:X: 2:1:4.048341
After:i:j:X: 2:1:4.048341

Hi All, I wish to know how we can convert the points
got by mouse click (screen coordinates) to the world
coordinates. At the moment after i capture the mouse
click events and get the points i am getting the
screen coordinates. How can i convert these
coordinates to the world coordinates.

try this
pt - point on canvas
canvas3d.getPixelLocationInImagePlate(pt.x, pt.y, point3d);
Transform3D temp = new Transform3D();
canvas3d.getImagePlateToVworld(temp);
temp.transform(point3d);

Hi Kelvin:
Thank you a lot for your valuable help in solving this
problem. I have eventually got the images rendered to
the fixed eyes. Now the only problem is that
sometimes there is portion of images flashing. E.g.,
when I close one eye and view the image through the
glasses, except for seei
