Clifford,
The Java3D tutorial is still very accurate. There may be a few places that
have changed, but on the whole the API has not changed since the original
spec in 1999.
If you have OpenGL experience I think you will pick up Java3D quickly. Most
of the concepts in Java3D can be traced back to
Hi,
there some ways to do what you want:
1)(hard) define correctly the geometry - inside and outside borders - and
use GeometryInfo to build the geometry;
2)(easy) define a simple Quadarray e apply a transparency texture map over it.
Do not forget to set a TransparencyAttribute at Appearance's
Hi,
I have already created my rectangle object with a hole in it. I used the
GeometryInfo. My question is when you create the object do you expect to see
what is behind the hole? In my example it seems that I cannot see the object
that is actually behind the hole.

I dont see good Java3D books having variety of examples. There are few good
sample programs on Sun's website.If you are good in scene graph programming,
you can alwayes write some sample programs. You can refer Prof. David R.
Nadeau notes on Java 3D, they are really good.

Hi,
I'm having problems
with Gimbal Lock in my JAVA 3D code ( all I need to do is rotate a simple cube
in 3 dimensions).
I initially
used
transx.rotX(anglex);
transy.rotX(angley);
transz.rotX(anglez);
trans4m.set(transx);trans4m.mul(transy);trans4m.mul(transz);transformGroup.
The basics of J3d haven't changed so the Sun tutorials are still quite useable. There
are also some tutorials at http://www.j3d.org although they are mostly quite specific
to individual topics.
If you want some paper, Daniel Selman's book ( http://www.manning.com/selman/ ) is
probably the best

Hi,
I
think maybe the way you create the Quat4f is not correct.
This
code works fine in my application:
public
void setRotation(float[] rotation)
{
/*Converts rotation angles into
quaternions*/
axisAngleX.set(1.0f, 0.0f, 0.0f,
(float)Math.t
I have been working on creating a custom orbit behavior for some time now,
but I have not been able to accomplish the desired effect.
I want to modify the orbit behavior to work like the following:
Moving the mouse up and down: Rotate the view about the world x axis (no
matter where that world x a
Title: Message
There
is obviously no difference since you're still using quaternions like euler
angles. In other words, as long as you use pitch/yaw/roll you're always have
gimbal locks, regardless of what intermediate transformations you use. If you
don't want gimbal locks, just stop using
Why don't you look into the source code of OrbitBehavior ? I didn't have any
problems modifying it to suit my needs. What you're saying is simple to
realise, actually you'll only have to remove some code from OB.
Cheers,
Florin

Yes, I expect to see through the hole. if you don't see anything, then your
rectangle doesn't have a hole. Btw, if you want to see something through the
hole, you must have some other object behind it, isn't it ?

Yes, we are working on the schedule for 1.4, and now that we have the
contributer agreement in place, we are in the process of getting people in
the pipeline for developer status. It takes a while to get these community
development projects rolling.

Hi all,
I am writting an application which requires me to
refresh the screen very often. I tried using
removeChild, but guess the memory was not deallocated
and moreover I was getting a multiple parent
exception.
The only work around is Detach. Which is documented to
not deacllocate the memory.
