Hi, I'm trying (for a long time) to make a LineStripArray with color, but it
appear black. I'm using a lit scene, so coloring attributes are ignored.
I make a geometry colors and material color, but none of them seems to work.
I have an ambient and a directional light. I put spheres and they are

I believe you need to use a ColoringAttributes object. My code (which works
fine) is below.
LineStripArray lineArray = new LineStripArray(n,
LineArray.COORDINATES, stripCount);
lineArray.setCoordinates(0, coordinateData);
// create a new appearance object for the grid

Hello all.
I have a problem with the animations.
I want to animate a robot arm with for example 3 articulations. When i
push a button i want to rotate one of this articulations a number of
grades in the axis i choose. How i can do that?
I'm trying to detect accurate collisions between boxes. I am modifying
the TickTockCollision example. I've remove the animation code and added
picking behaviors (rotate and translate). When I try to detect collision
the result is really unaccurate. I send you a snapshot for you to see
it.

Hi all,
I've been searching through the archives for this, but I didn't find
a definitive answer... is there any implementation of nurbs for Java3D?
As far as I know Java3D is polygon oriented, but I thought there could
be some nurbs primitive that tessellated the nurbs into an appropiate
Hi:
Please try to use USE_GEOMETRY as speed hint,
the default is USE_BOUND

int speedHint)

Hi,
Does anyone have a good example for utilizing the

Line2D.Float) and there are many Text3D objects in the scene, there seems to be

Hi,
There is an open bug 4191172 - Text3D rendering problems
for it. It happens for some Win32 fonts only.

Hi,
A bug 4336464 for investigation. It happens
when abstract leaf Node is extends. For non-abstract
Leaf Node there is be no problem.
Thanks for your bug report.

Has anyone else tried running J3D code on Win

Yes, we have run all versions of Java 3D on Windows 95, 98, NT 4.0, 2000
Professional
and 2000 Server. No problems on any platform. Note that the Unix/Windows
JVM's have different syntax for the -msm and -mxm command line options.
If you mess up the syntax you may get no error or warning message
