sorry,
can't agree with that:
compiling with jdk 1.3 beta -> flickering animations
java3d alpha 1 and jdk 1.2.2 / jdk 1.3 beta -> desktop gets frozen (winNT4 &
Viper550) and picking results in a NPE.
IMHO the most stable combination is still java3d 1.1.2 & jdk 1.2.2

Hi,
Have anyone tried to implement collision detection behavior on a point by
point basis. For example, a set of coordinates are stored in a text file and
use to translation and rotate an object in space. And collision detection is
applied to detection whether collision occur at each coordinates.
Hi..
I used to program in Java, but I'm really blind in
Java 3D.
I have to make a rotating globe with images in it.
Images consist of continents, and sure it must be changed in every
rotation.
How to combine those images with the 3D
sphere?
O yes, each image is like an image map. Several
Hurrah!
I will look forward to testing that out myself. I'm gearing up to wipe my
system and reinstall 1.2. I will take great joy in replacing the lengthy
Tornado Labs Java 3D installation instructions with the simple words:
"Install 1.2"
Sincerely,

Enough bugs have been fixed that if you now go download & install the
most recent Java 2 JRE & plugin, taking all the defaults, and you then go
download and install the most recent OpenGL J3d, taking all the defaults,
you can run J3D applets and they work! Belated applause to the J3d guys.

Hi Andrew,
The current KeyNavigator implementation is similar to Billboard
and DistanceLOD in that it uses WakeupOnElapsedFrames(0). This
means that it will trigger, even though it should be idle. This
is most likey why your CPU usage is so high. The only workaround
would be to copy the KeyNav
Hi All!
My project is currently investigating Java3D, and one of the functionalities
we would need is tooltips for Canvas3D. Since Tooltips only exist in
JComponent, which Canvas3D does not derive from, I'm not sure how to get a
nice tooltip for an arbitrary position inside the Canvas3D. I've t
Hi Sunny,
There are no new collision API's in 1.2 alpha1. The implementation is
completely new, but the API is the same. If you think you found a bug,
please submit the test case to [EMAIL PROTECTED]

Hi Victor,
This is bug in 1.1.2. To get the correct bounds in 1.1.2, you need to
make the subgraph live before getting the bounds. This is fixed in

I have noticed some things here with the HelloUniverse example

Can anyone tell me why primitive shapes are not documented in the main
Java3d API?
I realize they are in the com.sun.j3d.utils package, but why? It would seem
that they should be part of the main API? It seems that especially for
beginners (like me) these objects would be used often, and documen

hi,
a good book that deals with computer graphics in 3D, written for newbies in
3D mathematics, is
"Computer Graphics for Java Programmers" from Leen Ammeraal, published by
John Whiley & Sons.

Hello,
I have written a class to rotate an object around the world x and z axes,
and accelerat/deccelerate along its Z axis, using a keyListener to get
input.
This has been quite complex for me, as I knew no vector or matrix maths, and
the resulting code for rotating the axes and the ship and th
What is more, each cell of orientation matrix is a multiple of
cosinus/sinus functions of rotation angles around each axis. Right now
i can't recall how this matrix looks exactly, but i do remember that
if rotation is made around one axis only (like rotX function does, for
instance), then the cell

Hi.
I am not a mathematician, so can't give a detailed account of the 16 numbers in
the transform3d, but I can talk you through how they work.
The transform looks like this:
xx xy xz tx
yx yy yz ty
zx zy zz tz
sx sy sz ss
You can see four areas of numbers. The upper left block are the

hi,
transform3D consists of a so called homogeneous 4X4 matrix, where the upper
left 3x3 matrix describes the orientation and the most right column the
translational component (x,y,z,1).
