Xj3d M8 Install in Linux?

Daniel M Garland

2004-01-13, 2:31 pm

Hi all,

I'm keen to get coding using X3D in linux but continue to have trouble
getting installed. I've waited for M8 which had better instructions than
before but to no avail. The sample .bashrc in the setup guide didn't
work, since having two jar files missing, aviatrix3d-all.jar from /lib
and xj3d-external-sai from /jars. Even fixing these gives me problems:
compiler the LoaderDemo from examples/loader gives

LoaderDemo.java:169: cannot access org.j3d.loaders.ManagedLoader
file org/j3d/loaders/ManagedLoader.class not found
int flag = VRML97Loader.LOADALL;

and the /examples/browser not resolving symbols with ECMAScriptEngine,
JavaSAIScriptEngine ...

If any linux users have got this going could you email me your relevant
bashrc lines so I can figure out what is going wrong.

Thanks
Dan

Join the club.

The only VRML anything I've gotten to work in Mandrake Linux 9.2 has
been White_Dune. And their "immersive" environment is impossible to
navigate.

I still don't understand why Web3D/VRML software companies and
developers are ignoring Linux as a workstation. The only 3D engine that
works *WELL* in Linux seems to be Unreal Engine and with its licensing
good luck using it for anything that isn't going to cost a fortune in
royalties.

Maybe you need to use the lasted beta version to use with a flock of bird
magnetic headtracker for navigation in a immersive environment...
Or do you have a other head tracker supported by Linux ? What type ?

On a shutterglases desktop (were use can not walk or turn your head) it is
useful to have a serial spaceball or at least a joystick/gamepad for
navigation...

Beside some commercial VRML software for CAVEs under Linux, there is
FreeWRL and OpenVRML. FreeWRL is getting better each day.
There was also a Linux Version of the blaxxun 4.2 cc3dglut program,

http://www.web3d.org/TaskGroups/source/blaxindex.html

that compiled under UNIX/Linux, but this version is not available for
the public any more 8-(

What were your problems with 3D engines like irrlicht or the nebula device ?

Actually I'm still looking for one that I can afford. What is currently
considered affordable is still way out of my price range.... I'm po.

I actually have an old SpaceOrb 360 kicking around... I should probably
see if I can get the thing to work.

OpenVRML and FreeWRL both require PERL 5.8 but Mandrake 9.2 severely
chokes if you try to run anything but 5.6. Plus I have some perl
scripts I use for work that don't run under 5.8 either, so either one is
out till my employer and Mandrake decide to upgrade...

Now, *that* is useful. I've scoured Blaxxun's web site and they pretend
their Linux client never existed. Thanks!

Not too big a deal... I'll try compiling it when I have a chance...
perhaps even make an RPM out of it or something.

Lack of applications that I know of. I'm sure they're out there, but
I've never heard of them. I know the Unreal Engine works well on both
Linux and Windows from personal experience and their community support
is pretty decent.

Thanks for the help. I'm a relative newbie to programming in general
though I've worked as a sysadmin for a few years... and I haven't really
looked at VRML since... uhh... like '97 or so. (VRML97 was stonking new
last time I played with it.) Right now I'm working with a few friends
on a pretty herculean hobby project that'll involve X3D (and probably
VRML) and a lot of C++... so I'm doing a bunch of research now. I'm
happy to see this NG is still going strong. I think I'll stick around
for a while.

Thanks again,

Brian

AFAIK, this is supported as a serial joystick under the Linux kernel...

I do not understand, why OpenVRML should require Perl.
OpenVRML is a rather pure C/C++ programm....

No, this *was* useful, the currently public available versions only contain
the windows files and a message how to compile under Linux, but it do not
contain the files needed to compile under Linux 8-(

AFAIK the version with the UNIX/Linux file was only available directly
from the blax(x?)un FTP server.

What would you do with the RPM file ?
You should reread the license file....

The RPM requires freetype >= 2.1.2 which causes dependency hell in
Mandrake. (see the bottom of this message...) My mixup.

You're right. $%&^&%^*^%%#*!

Not any more. Their FAQ says they're thinking about developing a Linux
version as if they never had one in the past... Grr.

Archiving for my own use so I don't have to recompile every time...
