We have released a new version, 431, of "Jun for Java".
The major changes since the version 421 includes:
* The QuickTime interface is modified to support Java 2 SDK
1.4.2 on Mac OS X.
* JunMoviePlayer and JunMultiMediaViewer are modified
according to a new key event handli
Hi
This article is very interesting for those who need to
load textures or write images.
Tiger also added several formats for read/writing
images as jpeg2000, gif, tiff and others.

Hi,
I have a question about rendering of geometry in a Shape3D.
In my program, I need at certain times to change the geometry component of my
Shape3D to display certain different geometry. I do this by a call to
myShape3D.removeAllGeometries() and then add all the
geometries I need by a

That's
tricky, so you need to use tricks ;)
The
problem is that the renderer runs in another thread that the one in which you're
modifying the shape3d.
1.
first option is to stop the renderer before you remove the geometries and start
it again after you've finished adding. pros: very easy
I can't use a Point Array as each particle has to be modelled as a 3D object
with distinct geometry and orientation. The simulation includes particles of
different arbitrary geometries (shapes with n-sided polygonal convex faces)
and the orientations change from frame to frame. Instead of dealing w
Ok, now I understand better. You can still use 1 TriangleArray holding all
your geometry. Better, BY_REFERENCE, and then you update it with a
GeometryUpdater. That ensures that the whole geometry will be consistent.
And, considering what you're doing, the fastest option.
Cheers,

Well after a week of playing with Java3D sound, I too am quitting.
And that's without even trying the spatial dependency stuff that seems
to provide headaches for the rest of you.

mean a 4 point QuadArray . It should not be a square ,thesides might not be
equal, and the points might not be on the same plane.Would you apply
different textures to it (textures with lines are better tosee the
difference) and see how it looks like? I want to know how to cont
Thanks a lot for all your suggestions. I've used IndexedTriangleArrays to
model the geometries as even though the coordinates data differs for every
particle, there are only 4 or 5 'types' or 'shape' of particles, such that
every particle of a certain 'type' or 'shape' uses the same index arrays. I
On Windows, you can pack these files into your installer:
j3dcore.jar, j3daudio.jar, j3dutils.jar, vecmath.jar
J3D.dll, J3DUtils.dll, j3daudio.dll
Load the DLL files with System.loadLibrary(), or set java.library.path
appropriately.
Same on Linux, only with *.so files.
I guess that it could be

Here is a good one :

Well, I've designed a part of my school in Java 3D with exact measures as

thing.

biggerbut that changes only on the x-axis of teh screen..if you know
