I don't know why but it seems to be easier to reference the java3d libs
in windows than in linux. I tried it myself and i can't get visolate to
find the libs in linux. So i decided to refactor the jar in eclipse and
include the required java3d libs into the jar. So for now only the
native opengl libs from the java3d package are needed anymore. And this
is quite easy.
Just download my new created visolate.jar from [1] and set the ld path
correctly. You need to extract the two files "lib3dcode-ogl*.so" from
the java3d zip file from [2] and copy them where you want. I copied them
to /home/user/rainer/lib and after that in the console do "export
LD_LIBRARY_PATH=/home/user/rainer/lib". Now you can run the jar file
with "java -jar visolate.jar".
But the export statement is only active in the shell where it was executed.
Ciao,
Rainer
