Hi,
let me just share my own experiences (hoping, it may help).
Since I use XFree 4, I can observe the X server crashing, when I leave
a Java 3D programm, no matter if using Netscape or the
appletviewer. This is, what is happening in about nine of ten times
with indirect rendering. With direct rendering I have not observed
those crashes.
There does not seem to be a relation to a particular version of XFree 4
or the graphics card. I have one computer with a Fire GL 1000 Pro
(Permedia 2) and one with a Voodoo3. Also I have used XFree versions
from 4.0 up to 4.0.2 with SuSE (6.4 and 7.0) and also tried RedHat 7.0
with all the same results. I am using Java 3D 1.2 from Blackdown (what
else?) and the XFree 4 rpm's from SuSEs ftp-server. What particular
jdk version (Sun or Blackdown) you are using, also does not matter.
I hope, the Blackdown team can fix this problem, since there are only
a few graphics cards (such as the voodoo3), for which direct rendering
is possible at the moment. I would be glad too (speaking for most of
us), if Java 3D on Linux could stay a little more in sync with Sun's
releases for the Windows an Solaris platforms, as, in my opinion,
Linux is one of the most important development (and enduser) platforms
and 1.2.1 (even in the beta state) the biggest progress in Java 3D.
Best wishes,
Ingo
