Does anyone know if anything has been done with Java3D in
CAVEs? I'm familiar with Java3D for the IDesk. However, a CAVE is a
multipipe system... which presents different complexities. I'd appreciate
any information anyone has.

In my code, I make the following call:
((Shape3D)n).intersect(path,_ray,dist)
Everything is appropriately valued so that no errors
result. However, I consistently receive the following exception:
javax.media.j3d.CapabilityNotSetException: Shape3D: no capability
I'm interested in understanding how Java3D is performing collision
detection. If anyone could provide insight or references and pointers,
that would be great. Thanks.

We're developing an application (using Java3D) in which we do
massive amounts of volume rendering. Presently, we have the Mitsubishi
VolumePro500. This has C++ libraries and drivers which bind to
OpenGL. However, it does its rendering in a rather tricky, non-standard
way. As a result,
I'm trying to use the ModelLoader object in the NCSA portfolio
toolkit. I'm working on an SGI Onyx II (if that makes a difference). The
loader doesn't seem to work for cobs and dxf's. Has anyone else
experienced similar problems, or am I just doing something wrong? Thanks.

I'm trying to use the ModelClip node in Java3D, on an SGI
machine. Does anyone know the support status wrt this object on
SGI's? Thanks!

I've heard and seen Java3D advertised as "network-ready". What
does this mean? None of the objects are serializable... If anyone
understands this, I'd appreciate an explanation - I'm doing networked 3D
graphics and would like to take advantage of this feature. Thanks.

I've been trying to find specific information regarding the status
of Java3D being ported to the Mac. What is the current situation? Are
there free-ware versions that can be used? Is there an official release
nearing completion? Does OS X have any significance in its
development. I wo
I can't say off hand what the problem you are having is. However,
just as something to mention, enabling stereo isn't the only thing you
have to do in order to make the image appear correctly. In order to get
proper convergence, you have to set the interocular distance (distance
between
I recently dealt with a similar problem. I found that I received
non-congruent transform exceptions when I set the transform3D to a
rotation of zero about any axis. In code, this would look like:
Transform3D t=new Transform3D();
t.rotX(0);
or
t.r

this answered your question.

My vote would be for Java3D. It provides a decently high level
for the creation of 3D graphics with acceptable performance cost. When
you consider the amount of time it would take to (1) create your own
engine supporting lighting, texturing, etc... (2) the problem of making it

I have discovered that the following code produces non numeric
results:
double thetaX,thetaY;
Transform3D t1,t2;
double[] a=new double[4];
Matrix3d mat=new Matrix3d();
AxisAngle4d angle=new AxisAngle4d();
...
t1.rotX(thetaX);
Is it possible to generate a non-affine (or
non-congruent) transform using only translation and rotation? These are
the only transformations I use and I consistently will get a
BadTransformException thrown at some point during the manipulation of
objects. Any thoughts on this would be gr
I've been developing an app in which I change the translate and
rotate attributes of TransformGroups residing above both scene components
and the viewplatform. While I stick to translations, I'm fine. As soon
as I start rotating objects, I consistently generate a
