Vladimir et al,
No, I am a first-time user of Java3D, and figured I'd start with the
latest-and-greatest. Why? Do you advocate using the older version?
I have stumbled upon one new piece of info that fixes my problem on my
machine here at home (JDK1.2.2, Win2K, hardware-accelerated video):

Usually u would like to attach ViewPlatform to TrasformGroup, so that
viewpoint could be moved around the scene. The rest is quite simple.
As soon as u like to know where the platform is u just call
getTransform(Transform3D t3d) function on that TransformGroup. In t3d
class there would be informat
Did u have similar problems with Java3D 1.1.2?

This class is for Texture coords generation when u set texture on some
shape. U can find info in many different places, among which are
Java3D spec, Java3D documentation and Dave's tutorial at
http://www.sdsc.edu/~nadeau/Courses/VR99/.

Hi,
I have created a scene graph which consists of a behavior node
(wakeupOnCollisionEntry() and wakeupOnCollisionExit()).
I am modelling an object which moves according to a set of coordinates
stored in an array. At the moment, I am experiencing some problems between
the collision detection beh
Hello,
Is there an implementation built into Java3D that
will return either the current position of the ViewPlatoform in the
VirtualUniverse (x, y, z), or that will return the position of a mouse click in
the VirtualUniverse? Any suggestions would be
appreciated.
I've tried , but there is no change. I've tried making one TransformGroup
for mouserotate and put TransformGroup for RotationInterpolator and the
shape under the first TG, and vice versa. Should I put something else? Maybe
there is a class to make it wake up or something..
Thanks...

What is TexCoordGeneration for? What is the form of
this class?
Where can I get more information about this class
and how to use it??

Hi All,
We are trying using Geometry Compression APIs.
After we loaded OBJ files into our application, then
we compressed these geometries, and saved out. When
we loaded those compressed geometries, we found the
spatial relationships among them missed, that is, all the
geometries were put at the

Are any of your objects partially transparent? I heard
there was a defect with how translucent objects were drawn when overlapping
each other.
This bug you're seeing might not have anything to do
with the fact that your Shape3D's happen to be in the same
group.

Hi All,
I'm wondering if anyone out there has some insight
on this. I created a class which defines several different custom Shape3D
objects. All of these objects in the class are add to a single 'Group'
object, and the getShape() of this class returns the Group object. This is
so that

I am having a problem with java3d1_2alpha1-win-opengl-sdk
and *any* use of a TextureLoader. All the demos that try to use
a TL fail. All my attempts to get such to work have failed.
I don't know if this is a Windoze issue - I've tried Win2K RC2, and
also NT4SP3. On both my desktop machine,
You are dealing with two problems here: determining the faces that define the
surface of your points and generating triangles and normals for those faces.
The Triangulator utility helps with the second problem but not the first.

Hi,
the RotationInterpolator overwrites the transform of the transformgroup
every time when its processStimulus is called.
So you see no effect of your MouseRotate.
You have to use a third TransformGroup for your MouseRotate.

sorry..I'd like to ask again..
I want my object to rotate itself and also can be rotated by user.
I make one TransformGroup for scaling, and one more TransformGroup (as a
child of the previous one ) for rotation.

How do I use the EYE_LINEAR and SPHERE_MAP options in the

Is there any good documentation about these features in Java3D, or the

What kinds of textures do I have to use?
Hi,
this is no solution for everyone but if you want to use tiff's or png
(because they have 8 bit alpha values!) you can use the Java Advanced
Imaging Api without the need of using a component.
Here's my code:
