Hello again.

I revisited the patio_radio scene so as to try to reach perfection. For that
purpose, I perform my attempts on high resolution images (1600*1200).

For this attempt #1, it still remains :
    -) some light areas in some corners
       (to the left, on the floor, under the arches)
    -) tiny splotchy zones by the arch half-rings,
       at the top right of the image

The fringe under the balcony seems correct.

Render time : 1 hour and 10 mn on a quad xeon @ 3.7GHz.

One hour is pretty good for such a large image.

Nice design and decorations! Yes, some colors would be a nice addition,
like colorful fabrics as curtains, some early evening sky and some
colorful not too bright lights. Looking forward!

The original scene is shipped-in with POV-Ray. The header of the file does not
mention
the author. Like most shipped-in scenes, it is intended to be for demonstration
purposes.

Well, it gives me some ideas for a nice oriental city scene. :-D

Very good indeed. The artefacts you mention are hardly visible, 
especially the second ones. The first ones are a bit more obvious.

Don't forget you can always use the "no_cache" option (I think uberPOV 
only?) to get a "reference" image. See attached, that took about 25 mins 
on my machine using "count 10" and "recursion_limit 3". You'd obviously 
need higher settings to get rid of the graininess, but at least then 
you'd have something to compare the radiosity version with.

Here is another attempt. A bit better for the top right artifacts. Could not get
rid of the others. Anybody wants to give a try ?

Though I know about "no_cache" feature, I am not sure I know what it does
exactly. The point /IS/ to get rid of /ALL/ graininess and splotched, at high
resolution.
