Hi,
Does Java3D have a "built-in" texture memory limit? I am using an SGI
Visual PC. I have a scene that has 150 textures, all 512x512. I can
display the scene just fine in VRML (so I know the machine can handle it);
in Java3D, the *first* 10 textures or so don't display. I don't get any

'A' is a class which extends Group. When 'A' is called, it
will display a Cylinder. 'A' also has a method called setValue which will change
the height of the Cylinder by utilizing the Morph object.
'B' is a JPanel, which uses 'A' to create a lot
U can play midi files together with Java3D, but not wavs. But it's
quite natural - none 2 wav or midi files can be played concurrently
in Windows, though 1 wav and 1 midi do can. That's because midi uses
another 'output device' - synthesizer. U may also wish to check up the example

Has anyone managed to set up JBuilder 3 Foundation to work with Java3D?
There is obviously more to it than just installing J3D in the foundations
JDK.
Currently I'm using FreeJava, which is nice for editing, but being a
JBuilder2 user would prefer to see if I can use JBuilder3 foundation
thanks
Hi all,
Back to this sound problem (at last!). Ok, first, in the file attached
to original letter (Readme.release) i found

I've run into serious problem. Nor that it is something new or
unexpected, but time has come to solve it. So, i have the following
exception thrown:

Does anyone have any URL's for benchmark sites?
We have already worked with BenchJ3D from Tornado Labs and would like to
find some comparison results from other benchmarks.

I'm trying to do the same thing. I had to write my own behavior class.

Hi Dean,
this is a simple example that describes how to let rotate your viewpoint
around an object. The object has to be in the center of its coordinate
system. The viewpoint has to be in the same coordinate system as the object
in question. If not, you first have to apply some coordinate

Hi Daniel,
if you want to let rotate an object around an arbitrary axis in an
arbitrary coordinate system, you have to transform the object into that
coordinate system.
Then transform it into the origin of that coordinate system and apply
rotation. You can get a transform3D consisting of all rota

Hello,
I have had troubles with the NormalGenerator. I have used QuadArrays of

Hi Jimmy,
Have you try v1.2beta1 ? This version fix the problem.
Please try the program in the attachment which is modified

Note that using canvas.stopView() will stop the sound

Paul,
This looks interesting, I would like to know more,. Have you, or anyone
else, done any of the following in Java3D:
* Keyframe Animation - if so, do you hold every frame in a seperate
scenegraph? can you generate in-between frames?
* Joints, Inverse Kinematics?
* Bones with skin deformation?
I agree with your comments. I will be the first to admit that I am not a
professional Java3D developer but right off hand I don't know how to access the
depth of the z-buffer at the desired x-y location. It seems to me that without
it you will have to run down the line of sight until you find

byReference and Yup are what is needed to prevent an internal
