Hello everybody,
thanks for your hints in installing Linux. Unfortunately I was'nt lucky
yet.
I installed JDK 1.2.2 sucessfully so far and followed the hints from Jacob
in intalling Mesa. When I try to run the "make exec" (see below) I'll get
a window with some 3D-Objects, which are changing every

Thanks - this does indeed get rid of the annoying warning

Hello Ingo or the others,
how can I find out which XFree86 I have installed? I am new to Linux.
And I get this error everytime I want to run some Java3D application.
So, what can I do now?
Is it possible that Java3D 1.1.1 would work?
Or can you direct me to some Installationtips on the web I did n

Hi Desiree,
to find out which version of X you have installed, type "rpm -q xf86".
I don't know if Java3D 1.1.1 would work, but I think it would. If you
need some special features, which 1.1.3 but not 1.1.1 handles
correctly (Don't ask me which ones!), it would be better but more
tedious to switc
First of which Linux distribution do you use ?

If you have installed XFree86 from a RPM package, you can write:
rpm -q Xfree86 (or as root use your graphical RPM tool).
Next if you compiled Mesa 3.1 yourself you should be using Mesa-3.1-3

hi there,
does anyone of you has tried to use environment texture in directX mode ?
I'm actually running an app using immediate mode rendering with directX.
Texture mapping is running fine, but no so environment mapping. OpenGL mode

J3D Team,
I'm having some difficulty getting the J3DGraphics2D object to draw properly.
I'm able to get Strings and images drawn on the Canvas3D, but it appears that
the J3DGraphics2D internal buffer is never cleared. So it winds up
superimposing my new draws over all the old ones. For example,
Chris,
Is your image the same every frame (that is, would you be able to see any
superimposition)? Do you use a transparent/translucent background? I found
when using a translucent background that it would just keep adding on top until
I got a solid color.
I also found that you have to call fl
In SuSE the installation and system manager program is called yast.
Try to start it as root and look what version of X you have. In
SuSE 6.3 the version should be XFree86-3.3.4 !
I dont think that's your problem. My first suggestion is to try to
delete your Mesa installation and download the Mesa

I can say the same thing. Except that I don't keep the reference on the

Chris, Rob,
The temporary workaround is to add
g2.setComposite(AlphaComposite.Src);
before
g2.flush(true);
which will eliminate the superimposing new draws
over all the old ones.
Hope it helps, Jean

J3D Team,
It's currently costing my application about 0.6-0.8 seconds to perform
the flush function (only one image drawn). Since this method must be
called every frame to achieve the desired results, my framerate is
annihilated. I'm running on an Athlon 750MHz with a GeForce256 card so

It runs beautifully and quite fast as an app. As an applet under IE5 it
