Some users do not have underpants to wear. ;)
Some only want to point and click.

That is who mostly use modellers.

It is a template, yes?
It is not for me to criticise what I cannot do myself.

If you are working only with the mouse, the program creates the standard file in
a style that is easy to handle.

#declare CoPigment = pigment{granite color_map{...}}
#declare CoNormal = normal{granite 1 normal_map{...}}
#declare CoFinish = finish{brilliance 2 ...}
#declare Concrete = texture{pigment{CoPigment}normal{CoNormal}finish{CoFinish}}
#declare Spheroid = sphere{0,1 texture{Concrete}}
object {Spheroid}

This order and the well-read

If the user writes himself, he does so:

sphere {0,
    1 texture{pigment{granite

color_map{...}}normal{granite 1
                      normal_map{...}}finish{

brilliance 2
......}
   }
}

Then the user writes here:
Lanuhum!Your importer does not work!
Povray does not find an error!!!
:)))))))

To read such a mess with no errors in the Povray written source code parser
almost the size of one megabyte!!!!!!!

I am not comfortable discussing it in this detail when I am not part of

And as they say in the SAP world. If there is only one way to do it. 
Then you are doing it wrong.

24 posts later. I wish I had just said. No I don't think there is.
Because I have not heard of any and I am looking for one too, Windoze 
though.

I have tested several more examples today. Unfortunatly, none of them worked.
Sometimes I see something, but this is very different from the povray render.
Here is one simple example below. A few tubes with bearings.
I see one tube,  but without colors and without bearings.

Probably we need to code one. It is probably not too difficult if we want only a
viewer (without modeling).

We could have a simple window with a display of the .png image and a few
buttons, to zoom, rotate around the object...When the user presses one button,
for instance a zoom, a line is added at the end of the .pov file to update the
camera, a command is sent to povray so that the .png file is recomputed,
then the .png would be redisplayed.

With python, for instance written in pygtk, this would work both for Linux and
Windows :-)

Good luck with it. If you manage to either find one or manage to code 
one. Let us know. It would be useful.

OK. I have played a little bit to see if this is doable and I have a working
"Zoom button". It is not as dynamic as I wanted :  it takes 2 seconds even with
medium quality to change the view.  But this is nevertheless faster than
changing the code, recompiling, redisplaying the image... If I am not
too lazy, I will go on and add a few  other buttons to play with the camera view
 ;-)

Hi Stephen, this is done. You can now inspect any pov file with a graphical
interface to move the camera around, zoom, turn you head on the right  ...

See the appearance ( not perfect) of graphical interface here:
 http://math.univ-angers.fr/~evain/_images/viewer.png

You can inspect any pov file, even if it is not modelled with pycao. Just adjust
the camera.file variable to the file you want to visit. But you
have to install the pycao modeller to use the viewer.
