Hi,
This is my last render trying to improve indoor lighting and radiosity.
The main parameters used in this scene are:
Resolution: 1800x1200 (resized to 800x533)
Antialias: +a0.1
Lights: 3 spot_light area_light 5x5, 1 point_light (fill light)
Radiosity:
count 50
error_bound 0.5
rec.lim. 1
(I've used low values for radiosity parameters in order
to improve the render time)
Render time: 2h30m
CPU: 3.4GHz, 1GB RAM
Comments? :)

You can come and clean *my* bathroom any time! ;-)
Seriously though... nice atmosphere.

Nice - what did you use for the toilet & taps etc?
Depressingly good modelling and a successful lighting test.
There's still something a little cg about this image though and I'm not
sure if it's the lighting or textures looking a little too "clean" or
just the perfectly straight lines on the tiles that are ever so slightly
aliased. (that said a photo of that much perfect tiling might look cg
anyway :-)

Hi,
All objects are made in AutoCAD, imported to the application I use (owner
application which can import AutoCAD models, render in OpenGL and add
lights and radiosity parameters, then export to .pov, .inc)

I'm trying to improve my lighting techniques with key/fill lights and/or
radiosity, also trying to learn the correct parameters for materials
(reflection, refraction, etc..).
The only way I get good antialias is rendering a big image (>3000 pix
weight) and after resize. I always use just +a0.1, because other options
like +a0.1 +am2 +r7 +j takes too long to render and no improvement is
obtained.
Thanks for all comments,
JSR.

Hi JSR,
Wow, I'm commenting on two bathroom images in the same week :-) I think
the modeling is exceptional, and you're doing well. Nice use of the towel
and soap bottle. I'd love to see more of those little touches.
The lighting could use some warming up, in my opinion
(same thing I saw with the other bathroom image). I'd recommend checking
out Jaime Vives Piqueres' excellent, and free LightSys at
http://www.ignorancia.org/en/index.php?page=Lightsys
Speaking of towels, Jaime also has some VERY interesting cloth renders on
his homepage :-)
Rock on,
George

And with +a0.1 +am2 +r1 ? This should be faster than just +a0.1
with no quality loss (note that +am2 +r7 may take up to 1849 times
more samples than if you specify neither +am nor +r !! no wonder you
find it slow)

+r7? That's 7 level of recursion. Exept in some very special cases, it don't
improve anything. The default recursion level of 3 is usualy suficient. If not
suficient, you can go up to 4, or 5 if you are VERY picky and pacient.

Hi,
I think that LightSys (from Jaime Vives Piqueres) is a very good tool, but
at the moment I prefer to use my own light setup in the scenes, in order to
understand the parameters and their behaviour.
The antialias parameter: +a0.1 +am2 +r1 is faster than just +a0.1 and the
result has the same quality, thanks guys!
I've discovered the importance of good textures for walls and floor instead
of just simple tiles. The image attached is an example.

Wow! What a massive improvement in visual impact! (Thomas De Groot: mind if
I borrow your expression? ;-)) I can understand wanting to learn on your
own and not just wanting to plug someone elses system in all the time.
Speaking of that, I think Jaime has a good grasp of textures (which you're
obviously learning fast). His room and cloth renders might help you.
Render on,
George
