Someone posted a link to a free C compiler recently in p.o-t.

I know some C. I could try to write a converter but this would definetly be
the most ambitious project I've ever done and I havn't coded since last
semester.

So don't hold your breath :)

Crossroads won't retain Wings materials if you export via 3DS format.  You 
have to use the Wavefront OBJ format.  Crossroads will strip the material 
colors from OBJ imports, but it will keep the textures separate so you can 
put the proper textures in place by editing the pov file.

Exporting geometry from Wings into Povray via Crossroads is a bit of a 
black art.  For organic shapes, be sure to resmooth everything in 
Crossroads or you'll see facets everywhere.  Also be aware that high 
polygon counts are almost always necessary to avoid ugly artifacts.

I suspect that your soccer ball might have too few polygons for it to look 
right.  Try smoothing it a few more times in Wings.

Not yet.  3DWin used to be freely available, but the author pulled a bait-
and-switch and made it crippleware.

I have started to write a multiformat conversion utility which can read 
OBJ, LWO (both version types) and 3DS and export into POV, but I don't 
presently have that much time to spend working on it.  Since I am planning 
on releasing the tool under the GPL, I am prepared, however, offer up what 
source code I have (C++; the OBJ importer and core data structures are 
mostly written) if anyone else wants to take a shot.

Not to my knowledge.  This route is probably, IMO, the best option for 
decent Wings to Pov export.

You think correctly. ;-)

In times like this, I really feel ankward since I always chose other
languages to learn, and never tried C.. But I'm not going through a big
learning process for the sake of connecting a modelling tool with POV-Ray,
when I already see how to do it with POV ... Wouldn't this be a good
all-round command for the next version of POV-Ray? :

#fopen Reader, read
#read ( Reader, file_position, read_length, string_variable )

I can see what you mean there.  This is most likely from a shadow line
artifact, read section 9.8 in the 3.5 docs for more information.

GOOD NEWS!

Download a plugin for Wings3d here and it will export directly to POV mesh2.
I tried and it works.

Borland is giving away a c/c++ compiler vs. 5.5
(command line only, though :(   )
just go to their website and signup, then download.
It works well

I tend to use OBJuvPOV to convert from Wavefront OBJ to POV Mesh2 with
uvmapping.

OBJ files don't contain the details of the materials, they only specify
the name of the material that is associated with each polygon, so the
colours will get lost in transit and you have to make fresh textures in
POV.

The OBJ file format seems to be rather weakly specified, and OBJuvPOV
seems to cope with most variations better than most things I've tried,
but it can't handle OBJ files that don't contain normals.

It's at <http://www.geocities.com/who3d/>.
