Post file conversion

#1  duttond 05 Oct 2006 16:53

I have several ways to create large areas of randomly generated cities and the output is to POVRAY 3 or VRML 2.  All the programs and converters I have can only read VRML 1 or POVRAY 2.2.

Does anyone know of a inexpensive, or free, file converter that will go from VRML 2 to VRML 1? VRML 2 to Wavefront OBJ? VRML 2 to 3ds? VRML 2 to Lightwave?  POVRAY 3 to POVRAY 2.2? POVRAY 3 to (any of the above)?

NOTE: I also found out that my IE at home interprets VRML but the one at work does not...I'm still investigating that one. If I figure that one out, I can post planetary systems, cities and other 3d objects on my web page so anyone can wander around in them.  That will be a kick.

Hi duttond!
There's a thread about a free proggie called PoseRay
http://posetteforever.com/viewtopic.php?t=1885
This should do the job   It loads VRML 1 and 2, as well as all the native PovRay stuff. And a lot more. A "must have" IMHO
For visualisation in your browser go

@ Tormie
VRML ( *.wrl) is a file format used for virtual reality such as 3D chat and other online 3D visualisation

Thanks but I've tried PoseRay...When I load the model from POVRAY 3 or VRML 2, it says the model has no facets, no verticies or both no facets and no verticies.

It worked for me.
Have you tried the newest version? The latest release is only two weeks old

Maybe you could mail or post one of the files for further investigation, if it's not too big...
Something could be messy with the file itself

Here's a file created by CityGen version 0.9...
http://www.duttond.topcities.com/Star_Trek/CityGenV0_9.wrl

...and another created by Fractical World Editor version 1.6...
http://www.duttond.topcities.com/St...Explorer1_6.wrl

I have problems reading either one in PoseRay (no faces on the first and no verticies or faces on the second).  There's no need to hurry on this as I'm going on vacation tomarrow and won't have email or Internet access until I return on the 19th.

On Friday, I'll be going to a photoshop CS conference but, for the rest of the week, you can bet I'll be relaxing - away from the stresses of the job.

Just made a quick check of the files and had the same problemes.
I'll compare them to some working files I have on my HD somewhere, the next days.
Happy holydays, duttond!

I'm sorry, but I didn't have the time for further investigations, yet.
I'll stay tuned, anyway

Hi duttond!

Haven't been around a lot lately since my head is always inside a wireframe working on several modeling projects.

You may want to upgrade to citygen v1.5. I looked at one of your files and it was generated by version 0.8/0.9.

I have used v1.5 to generate a city and exported it with the "export to pov" feature and then rendered in povray v3.6 with no problems.  It appears that this native "pov" export feature was added in a later version of the citygen.  The vrml format I am not familiar with.

I will try to take a look at some programs I have and see if I can add anything else.  As far as no vertices/faces etc, that is usually a file incompatibility error, or the method in which a particular program saves a file in a non-native format.  I had this problem when I was working on my first model, the PF Country Club.  I was using a CAD program, and trying to convert it to obj format by going thru Poseray.  My CAD program had various ways of grouping objects, and if I used one which was incompatible with Poseray, I got the same error message about no vertices/faces, etc.

I know this is not a specific answer, but maybe it can help point in the right direction.
