Never say never however ;-)

I shall make a second /final/ render tomorrow with better visible caustics.

The post-final render?
:D
And don't forgot to add some drops of water on the floor. And a little 
veil of mist due to the evaporation. And...

Look:
http://www.povray.org/documentation/3.7.0/t2_3.html#t2_3_7_7

If the object doesn't radiate photons (walls), the line photons { }, in
material, is absent

spacing use to me is unclear.
In other cases the system hangs
Instead of [spacing] I use [count 10 000 000]

In docs:
 global_photon_block:

photons {
  spacing <photon_spacing> | count <photons_to_shoot>

I typically use spacing, starting with 0.1 and working downward until the
"focus" of the caustics is dense enough. In this scene my renders use:

spacing 0.00045

That was not the problem. Photons /are/ visible in the image above but 
very diffuse. I just forgot to adapt the spacing parameter in 
global_settings to better values.

In Blender, the modifier is called "Solidify".

Excellent. It would be a good idea to use it standard for scenes like 
this test one. I noticed some light leaking along edges also in 
Luxrender and in the smaller image of the 'Other' renders, besides POV-Ray.

No, I am quite content with what I have achieved. I have added photons 
to my panoply and learned a few fundamental lessons. My ToDo list is 
just a tiny bit shorter than it was. :-)

Would you mind sharing the render times with and without POV specific objects?

And this is the final final render.

Version 3.7; +a0.01; photon spacing 0.001; 6 threads; 3 hours render time.

At windows on a wall pass through isn't included?

I think that would be interesting.
There are two items of interest:
1)Memory:
#declare a mesh and use a copy, folding chair.
Use one texture for the hole mesh, split folding chair, use one texture for each
part.
2)Simple geometric shapes, use sphere.

Very nice, Thomas. Thanks for your suggestions on my previous attempt. At this
point I'm calling this my final render (final final may come later ;)

Again, I like how the images are interpreted differently from person to 
person. Good work Robert.

I will be glad to see final final :)

Hi all!

I showed works of Thomas de Groot, clipka, Robert McGregor on our site, but
responses, comments aren't present. Nobody abuses, but also only the +2 rating
More and more users start using Cycles-render built in the Blender. It strongly
concedes, loses to Povray in creation of glass objects, but, users will better
exclude glass from work...
And I don't like Cycles
I worked today over development of export of hair from the Blender in Povray.
However, far I didn't leave

To all participants (taken part) dough many thanks!

Let us know if you get some interesting comments on the images. I am 
always curious to hear from outside the community.

I have not (yet) mastered Blender (on my famous ToDo list) so I don't 
know about the possibilities of Cycles. However, I shall keep my eyes open.

What you say about hair export from Blender interests me. Keep us informed!

I was very happy and interested to participate in this test and it 
learned me a couple of things besides, so thanks to you too for 
initiating this and for working on these export possibilities between 
Blender and POV-Ray.

I wrote that comments aren't present.
Nobody undertook to criticize works.
On our site there is one of developers Luxrender (aka SATtva), but even he told
nothing though claim that it was interesting to it to see your works

Export of hair is present at the official version of the exporter for a long
time. sphere_sweep is used. There is no UV export for color fur.
I want to refuse sphere_sweep, using while and bezier_spline.
As I want to include UV
It is good to look as mister Robert McGregor created hair:
http://www.mcgregorfineart.com/images/competitions/rwm_VesicaSaAngreal.jpg
Me as the correct material of hair interests.


Personally me animation, not photorealness interests.
Povrey is rich with patterns for this purpose
In my version of the exporter difficult textures with use of pigment_pattern,
pigment_map, texture_map, pigment_map, slope_map and other are already available

Thomas, you are obviously in need of a Round Tuit (see my post of the
same name in p.o-t). In order to save you time, I have attached one here :-)

No need for activation. It works straight out of the box.
Incidentally, cloning is easy as well. Give copies to those in need.

Good thinking. I shall now retire back to p.o-t which is where I belong.

Incidentally, beautiful work by all of you.
