| Hi,
I want to import a vrml scene from our design software (proengineer).
But this scene contain many many vertices and is too heavy to load for a
web3d scene...
I want also to add sensitivity on different part of the scene (moving
part on demand, adding comments, ...).
Does anyone know a tool that can help me (to reduce my scene and add
sensitivity) ?
thanks
ps: I'm a beginner in vrml

why not start here and maybe speak with the X3D CAD working group.
Thanks and Best Regards,

| Hi watayoune,
You could try VizUp Reducer to reduce a huge scene.
Feel free email me directly if questions, I am happy to help you on the
way.
Keep in touch

| hi watayoune,
On the sensitivity issue...do you want this to be shared?
Meaning, a user on one computer can see real time changes
done by another user on a different computer?
I ask this because you want a method that adds comments as well.
If "shared" is what you are after, that can be done by
Deep Matrix, an EAI java based multi-user system which is open source
and free. It works with the the three major 3D VRML plugins.
However it does require the use of either I.E. and the old Microsoft
Java Virtual Machine or Netscape4! It will NOT work with the Sun Java
plugin!
If you are going to use this in a controlled user enviroment, the
computers
can certainly be configured to work with it.
You can try my latest version of Deep Matrix online here: ( not fully
debugged yet, but functional )
http://www.sevenemeraldtablets.net/...ect/Testclient/
Just type in anything for a password. Once you are in and the scene
and applet is fully loaded, you'll see a jpg of a purple Mobius strip
in the lower right. Click on it and it will load into the scene.
Then highlight the name "Moby" and press the "Move" button.
A set of controls will appear that will let you rotate and re-position
the object in shared real time. The teal ball attached to "Moby" also
revolves the strip in shared real time.
If just animations for just a single user is you goal, that can be done
by a program like Spazz ( now Vizx3D )
As far as adding comments go, here is another EAI Java program
that can accomplish that, but it is limited to Internet Explorer
and Cosmoplayer and needs *some* work as well.

Unfortunatly, it only reduces redundant data (like unneccessary points/indices
of a shape), which is a good idea and the numbers of characters behind the
comma (which can be not a good idea in general).

I am not a direct user of ProEngineer, but a user showed me, there are
somewhere three size options when exporting from ProEngineer.
Unfortunatly, the size is reduced by reducing the number of characters
behind the comma, which may be a bad idea, especially if your modell
consist of multiple objects and one of these objects is a single side
of the whole object.
In general it may be worth to take a look, if you can export your data
from ProEngineer via a other 3D data format and export VRML from a
programm like 3D Studio MAX, maya or Cinema 4D, cause the last versions
of these tools have builtin polygon reducers.
You can also think about using a NURBS based tool like rhino 3D, cause
in rhino 3D you can type in the number of polygons you want to have
in the VRML file - unfortunatly not all NURBS based tools have this option 8-(
> I want also to add sensitivity on different part of the scene (moving
> part on demand, adding comments, ...).
3D Studio MAX include a tool to build clickable VRML97 animations, but
for more advanced tasks you may want to use a specialised graphical
VRML tool/editor like cosmoworlds, white_dune, spazz3d etc.
In general, it may be a good idea to divide shape data and interaction.
VRML97 support a Inline command, that allows you to incorperate different
VRML files into a new VRML file. Typically then the inlined files are
different parts of one shape or different parts of one 3D world.
This is especially usefull, if your 3D modelling tool allows you
something like "export only selected part" or "do not export hidden parts".

You can find simple interaction examples in

| Pro Engineer Just save as vrml and get Internet Model Optimiser from
www.parallelgraphics.com This is a brilliant tool, infact have a
look at Virtual Manuals.

| Hi, thanks for all your response,
about Parallelgraphics, i've tried Internet Model optimizer (demo) and
it looks like à good polygon reducer.
But i can't really test it (demo version: save disabled).
As it seems that you've used IMO, does the filesize announced (when
publishing) is the filesize really produced in full version because for
my model it seems amazing (including inlines ?) !!
My model will (when i'll buy IMO) a 800 ko model, is it good or does i
have to reduce it again ?
And what about Internet Scene assembler (I'can't test it with my too
large model), is it easy to use for a non designer (i'm a programmer) ?
thanks
Watayoune.

| As a one off I will Optimise your file to show you a few examples if
you wish. As for too large a model this will not be a problem once
all yor files have been pre-optimised for ISA. ISA is used by
children also and there is some fine examples deep in the PG website
somewhere. I remember seeing some a few years back, infact the made
the model of Red Square a very impressive scene. You can if you wish
zip your file and send it to me and I shall return it optimised at a
few sizes as examples of the power of IMO. Just remove naespam from
my address. (naespam) Scottish for no spam ;-)

| Hi jake,
Thanks a lot for your proposal but i've got only one model to test (for
the moment) and unfortunatly this model is rather confidential, so i
can't send it to you. But, i'll try to find a "public" one with the same
"complexity" ...
Do you know a vrml viewer (for IExplorer and Firefox) that don't need
the user to download a plugin.
I've seen example with blaxxun but don't really know how it works ???

could try AC3D,
http://www.ac3d.org/
the new v5 has a surface reducer function which i've tested on vrml
here:
http://vrml.portland.co.uk/ac3d reduce test/example.wrl
the first helocopter has the over five ( on the right ) as LOD, which
have been reduced by, in sequence, 0%, 50%, 80%, 98% 99%, it managed
better than i've seen before, however in its importers it only has
vrml1, does however export vrml1 and 2.
( the original helo was in vrml1 from
http://www.topedge.com/panels/aircr...ng/bellrg-a.zip
)
has some strange artifacts around the tail in cortona 5, looks find in
blaxxun 6.2, if you try this and use a different browser please port if
you see this, it may be an issue with the vrml2 exporter.
BTW i did found a couple of small bugs in the vrml2 exporter, i'm
goiing to report.

AC3D is a general purpose 3d editor so its easy to have different parts
of the vrml reduced by different amounts.

There is also a few java applets outhere have a look for Jet and IBM
have one also I will try and find it again, it is very limited in
funtionality though.

The problem with pure java applets is usually performance. Pure java
do not support the 3D graphics hardware accelleration of the graphicscards,
which are very important for realtime 3D tools like VRML browsers.
There is also a java-API with hardware accelleration called java3D, which
solves this problem (e.g. used with (some versions ?) of the Xj3D browser),
but running java3D from the browser need advanced java-plugin technics 8-(

Is JOGL part of a standard java installation ? I suspect, it is not.
If it is not, you have the same problems to have JOGL on the end user
machine as with java3D 8-(
