VRML World.... please help if u can... :)

[Anonymous]

Hi all, hope you are fine,
i want to ask about something please..
now i'm using archicad to create vrml world for virtual mall... , first i created the building and put object inside it...
then i would like to save it as wrl file "vrml world" ... but when i tried to open it using VRML viewer.. it was so big and hard loading.. so i cant open it.. because it's size... so.. i tried to save each object as a wrl file and attach it in a wrl main world... but it will be a very complex task to save each object if i have over 100 object in the project....
i ask if there are a solution for saving the project as VRML world in a simple way.. and small size or to find a way to save the hole project as many wrl files file to each object without saving each object separately!!! or any other ways to be able to create my VRML world ??????
waiting for a replay as soon as possible

It seems you are running into the limits of VRML. ArchiCAD can easily produce and manage levels of complexity that crush the capabilities of VRML. I recommend stripping the AC model down to the minimum that will tell your story.

I haven't done much with VRML in a long time so I don't know if there are any tricks for linking up separate parts to make a larger whole that still runs acceptably well. If so you probably will be stuck with saving each bit separately as there is no way (that I know) to publish the parts automatically.

Thank you for your replay

You could use different layer combinations, e.g. one for the walls and floors, one for the furniture etc...

Then you should start scripting the VRML model yourself (not from ArchiCAD).

But what you are trying to do is just difficult: ArchiCAD can generate an enormous amount of geometry, so better to optimize it first.

There are VRML compressors out there, but "garbage in, garbage out" is still true.

The vrml generated by ArchicAD does not need to be compressed, it needs to be optimized (corrected, adjusted and improved), wich is different.
You can use Vitruvian Studio to optimize (one click process), compress and run the vrml generated by ArchiCAD (without reducing the number of polygons).
http://www.vitruvian-studio.com
You can save as vrml file the whole scene or different parts of it (building, furniture, ....) and add each part separately. This reduces the size of the scene, especially in case you need to add the same object for many times. (But for OFFLINE Realtime presentation the size of the scene is not important).
Also, with this software you can join in the same scene different VRML objects from different CADs.
Moreover , for a virtual mall, you should be needing to apply a visibility limit to the different objects (when the camera moves close to the object it appears in the scene, when the camera moves away from the object it disappears from the scene), in this way you can build and navigate huge spaces without straining your video card.
