installing Xj3D on linux AAArgh!

Is this the correct forum for this discussion?

Firstly, i was blown away by Java3D this morning -- i had been looking
at VRML viewers for Linux/Windows (want cross platform client) and
when i saw FreeWRL my heart sank and OpenVRML has a 0.5Mb cpp file
that won't compile for me. Then I thought i'd give Java3D a go as a
last resort .... and it's fast and feature-ful. I was muchly
encouraged.

So I'm going with Xj3D if all works well.

...it appears that the user needs yet another library - Aviatrix - to
get browser.sh to work.

And YES!...
$ find . -name \*.java -exec grep -H viatrix {} \;
./src/java/xj3d/browser/renderer/ogl/ElumensBrowserComponent.java: *
An Aviatrix3d specific rendering component.

so Xj3D DOES depend on Aviatrix.

So here are the correct Installation instructions for Linux/Unix:
$ wget http://www.web3d.org/x3d/applications/xj3d/Xj3D-M9-unix.tar.gz
$ wget ftp://ftp.j3d.org/pub/aviatrix3d/AV3D-bin-Beta2.tar.gz
$ tar zxf Xj3D-M9-unix.tar.gz #creates Xj3D/
$ mkdir Xj3D/AV3D #(AV3D-bin-Beta2.tar.gz has no top level directory)
$ tar -CXj3D/AV3D -zxf AV3D-bin-Beta2.tar.gz
$ cd Xj3D
$ vi configure #create a new script to write out a correct browser.sh
#!/bin/bash
export TOP=`pwd`
JARS=`find $TOP -name \*.jar -printf %p:`
CLASSPATH=`find $TOP -name images -printf %p:`
export CLASSPATH=$CLASSPATH$JARS$TOP
echo "Using CLASSPATH $CLASSPATH"
BRW=./browser.sh
rm -f $BRW
touch $BRW
echo "#!/bin/bash" >>$BRW
echo "export CLASSPATH=$CLASSPATH" >>$BRW
echo "java -Xmx256M xj3d.browser.Xj3DBrowser" >>$BRW

chmod ug+x $BRW
echo "Created $BRW as executable"
$
$ ./configure
Using CLASSPATH /home/jack/pkg/Xj3D/images:\
/home/jack/pkg/Xj3D/apps/browser/images:\
/home/jack/pkg/Xj3D/jars/xj3d-common.jar:...
Created ./browser.sh as executable
$ ./browser.sh
Uncaught error fetching image:

!!!! I can't win, i've put all the jars in the CLASSPATH as well as
all the images directories. and it still doesn't work.

Help greatly appreciated.

There is a another "free beer" VRML viewer for personal use for Linux/Windows:
Octaga.
It looks like, there may be problems to display the text node and sometimes
problems to find files but it may be worth a look.
At least, it looks like it supports "directOutput TRUE" scripts like in

http://www.web3d.org/x3d/specifications/vrml/ISO_IEC_14772-All/part1/javascript.
html#AccessingOtherNodes

which is rare in Linux VRML viewers 8-(

AFAIK, the current non development version of Xj3D still supports both the
java3D and OpenGL/Aviatrix3d renderer. So finding sourcecode alone
do not say much...

This do not look like a Aviatrix3d related problem....

AFAIK, there is a advice of the maintainers, to put the jars into
directories like lib/ext in the java tree...

so long

doesn't plug in to a browser, tho.

well, i've found a raft of other jars and dll/so's that browser
depends on. see the end of the post for a shell script commenting on
how to get these and install them. the shell script takes the DEV and
APPS snapshot from xj3d site and constructs an appropriate browser
shell scripte

now, i've put JOGL, JOAL, and everything else but the xj3d classes in
$JAVA/jre/lib/ext.
i run browser, and i finally get a window displaying before **CRASH**
another one bites the dust. from a vague article i read a few hours
ago, it seems this problem may be because my X was built with a
different g++ to the JVM. I remember why I don't use C++.

here's the output of the JVM... the shell script comes after it:

[jack@linux xxx]$ ./browser

We have created an autoinstaller for linux now.

Please try this:

http://www.xj3d.org/download.html

By default we use Aviatrix3d which is our Java Scenegraph API. You can
change it to use Java3D by adding the -j3d switch to the browser.sh
