vrml viewer with Ubuntu

Hi,

I am trying to watch remote wrl files under Ubuntu 7.10 but not success :-(

First, using Synaptic packages manager, I installed openvrml-lookat. But
i still can not see wrl files in firefox. How to use it in firefox or
directly? Gtklookat seems suitable for browsing local files, not remote one.

Second, I tried to install Freewrl. I downloaded
freewrl_1.19.9_Ubuntu7.10_i386.deb but I can not install it. Using
gdebi, I can an error message : Could not open
'freewrl_1.19.9_Ubuntu7.10_i386.deb'. I changed the rights to
read/write/execute for everybody without changes. When using Synaptic
packages manager and using the option "installing downloaded packages",
the deb file is grayed and I can not select it.

Help will be welcome.

Anything related to OpenVRML called *lookat is positively ancient.

I'm not familiar with Ubuntu; but if you can, I'd encourage you to give
OpenVRML 0.17.5 a try.

I am running FreeWRL happily every day in Ubuntu studio (based on
7.10, but with an Xfce4 WM). It is the browser component in a project
I am working on.

Because I wanted the latest, I installed a source version directly
from the FreeWRL site:
http://freewrl.sourceforge.net/ It also contains slightly older .deb
files

The current version there is 1.20.2 and you can update to 1.20.3 plus
fixes via CVS, at
http://freewrl.cvs.sourceforge.net/f...l/?sortby=date

The project is very actively maintained and upgraded, and if you want
to do any External Authoring Interface work, then it is the best
browser for you to use.

Usually, .deb files are installed with

dpkg -i something.deb

with root rights. This usually do not solve dependencies automatically, so
you may need to install some other packages before. Simply read the
errormessage to find out, what other packages are missing.

I did

sudo dpkg -i freewrl_1.19.9_ubuntu7.10_i386.deb

dpkg-deb: 'freewrl_1.19.9_ubuntu7.10_i386.deb >> n'est pas une archive
au format Debian [NdT : is not a Debian archive file format]

I also tried with the debian package :

sudo dpkg -i freewrl_1.20.2-1_i386.deb

It can unpack the deb file but can not configure it due to a lot of
dependencies. Need libc6 2.7-1 instead of 2.6.1-1ubuntu10, libmozjs0d
1.8.1.5 instead of 1.8.1.4-2ubuntu5. freewrl not configured. (and also
problem with packages dependencies and updates).

Then, looking at aboutluings in Mozilla, I saw this was installed. I
was also able to see the test cone from freewrl.

But still not succesfull in viewing my world :

I also have a problem with your demo. When I download and view your
world locally, it is unable to resolve your inline references:

Inline { url [ "level0/level0.wrl" ] }
Inline { url [ "level1/level1.wrl" ] }
Inline { url [ "level2/level2.wrl" ] }

When run as a plugin, it hangs. Changing your demo file
to include a full path reference may fix things.

Relative path name should not be a problem. Using full path will
strongly complicate deployment.

Hanging and FF crash may be related to a not optimized use of Inline. I
use two levels of Inline. At first level, it use a switch :

DEF MONDE Transform {
children [

DEF Commutation Switch {
whichChoice 1
choice [
Inline {
url [ "level0/level0.wrl" ]
}
Inline {
url [ "level1/level1.wrl" ]
}
Inline {
url [ "level2/level2.wrl" ]
}
]
}
]
}

Only the right level should be loaded at a moment.

For the second level, I use a bounding box :

Inline {
url [ "block0.wrl" ]
bboxCenter 0.4251 0.7217 0.4461
bboxSize 0.8568 0.5565 0.9000
}

Again, it should be only loaded when the box is visible.

Could it be that freeWRL load everything at the beginning? (2400
files!!!) I know that the vrml Standard does not tell anything about
when and what should be loaded at each time.

I could see after re-reading your code, that relative file paths were
your
only option, and that therefore I would have no hope that trying to
run the
world locally would ever work. I have ask John whether there was some
sort
of way of tracking what FreeWRL was doing when it runs as a plugin.

I suspect you are entirely right, that FreeWRL tries to load all the
files
at one time. This would be logical behaviour under certain
circumstances,
with bad consequences when faced with 2400 files.

I am forwarding this post to the FreeWRL maintainers as well.

May be, I can make a single archive file that you can download and
expend on your computer. In that case, this a 42 MB file but I can build
a lighter sample (10 MB).

Sure. Send it to me as a zip or tar.gz and I will test it for you.
