With so much commercial product logos used, I don't think so. Besides,
it was not made for the purpose, so it's against the rules to use it.

I've focused my attention looking at the logos searching for the pov-logo
that I missed the "pov-ball" reflection he he he.

Pretty cool.

Now the pic concept really "strikes2 me ;D

Thanks. The texturing is really simple, for example the texture on the
table is just

texture {
  pigment { green 0.5 }
  normal {
    checker
    normal { marble scallop_wave },
    normal { marble scallop_wave rotate 90*y }
    scale 0.1
    }
  }
}

The textures on the balls are also as simple, just an image_map with
filter all 1, no ambient, and some fresnel reflection. It's the
subsurface scattering that gives it the juicy look. Glad you like it.

How did you implement the subsurface scattering? How noticeable an effect is it giving
to the
scene?

It's quite easy, actually.

First of all, you obviously need, well, subsurface scattering :), or,
in POV terms, scattering media filling a hollow object. Make it white,
so that it scatters all light equally. Make it realistic, i.e.
extinction 1

Then you need to ensure that light actually penetrates the surface.
Give all your colors a filter 1 (easy in my case, as these are all
image maps). With enough scattering on the inside, the white light
from inside filters through the colored surface and it looks like the
object is opaque.

As you might have seen in my original post, this approach causes some
problems at shallow angles, as the media does not scatter enough light
to extinguish all of it and the background can be seen through. To
avoid it, add an opaque interior_texture. For most realism, make it
the same as the external one, though you may wish to remove reflection
from it as it will only contribute to the render times and not to the
image.

Last, you need to avoid self-shadowing as it really kills the effect.
Simply putting no_shadow won't do it because then the object will not
cast a shadow on anything, and we don't want that. Light groups may be
an option, but it's easier to separate the surface from the interior.
Simply make two copies of the object, one being the "shell" - with
texture and interior texture, and the other being the "interior",
slightly smaller, with a clear pigment and object scattering media.
Give the "shell" no_shadow and you're in business.

To push things really on the cool side, give the "shell" some ior.
This bends the image inside so that you get a distorted terminator
line characteristic of subsurface scattering (see some MAX/Brazil
images implementing a s. sc. shader).

That's it, quite simple, really, but the result is good.

Very nice image, I really am impressed at the vibrancy of the texturing and
the labels.

It looks like the scene is set in an actual room, is this true? I get the
impression there is wood paneling for walls (from the reflections in the
orange ball).

Although, I would sincerely request that Blender be removed from the
table... sure it is hard to use, but far better than any other modeling
program (cost: $0.00 and open source!).

If for ethical reasons you can remove it, please move it to a less
vulnerable place.

The labels are logos ripped off the web or brochures. I can not take
any credit for those.

No, there's just the ground plane and the window (2x1 meters, 4 meters
away).

Nothing personal has been put into the placement of the balls. It's
just that Blender's logo is virtually the same orange they use for the
1 ball, and that one should always be in the front. That's why Messiah
is in the far left corner, for example - their purple matches the 12
ball purple perfectly.

If I put something else in its place, I might offend someone else. I
am surprised Lance hasn't yelled already :)

>If for ethical reasons you can remove it, please move it to a less

Blender has already moved to a less vulnerable place - in the public
domain, where all good software should be (need I point examples? :) )

>p.s. I now have some new wall paper.

Wow, that's by far the greatest compliment I've had. Thank you!

Very nice, i can recognize quite some of the programs featured but not

And i have two suggestions:

- animate it...

MLPov has support for it.  I did not yet see a HDR image with that kind of

I don't know.  Artists have used legally used trademarks without permission 
before.  Andy Warhol is an example.  It depends on how it is used and the 
laws of the countries involved.  

This is art.  It makes a socially relevant comment.  Here in the US you 
would be protected by the first amendment to our consititution.  

http://www.phillaw.com/html/trademarks.html


I would say that even if there was a legal issue, the companies would not 
be likley to pursue action if the legal fees exceed the amount recoverable.  
However this poster might be a zazzle bestseller :)

Come on, the window is just there for the reflection. As it is well
seen by the reflections, the window is not vertical but is facing the
balls - to give those familiar reflections. The lighting itself comes
from a 20x20 area light :)

If you can work out the maths, I'd gladly have the thing animated even
if it takes a month to render. Be sure to include angular momentum in
the calculations, because I *always* take the first shot with a
bottom-left english, starting 10 inches to the right of the cue
position and aiming slightly to the right of the center of the 1 ball,
so that the cue ball goes in the far right corner pocket. There's the
deal - I provide the imagery, you provide the maths, and we get rich
and famous and go to Hamburg, this time not missing the Repperbahn :)

Well Peter, I couldn't resist on doing this.

I hope you can forguive me, but following your pictures idea I created this
one, with the elements that you "forgot" to include in yours. ;D

I know the textures are terrible (except for your cool table cloth texture)
and the proportions are not accurate, but .... well, this is just a joke :)

Nice work.

Actually, the one-ball is yellow and the five-ball is that shade of orange.
Incidentally, most of the current rule systems for 8-ball (that is what you
were going for with the triangle-shaped rack, right?) do not require the
one-ball to be in front, only that the eight-ball is in the center.  Perhaps
you were thinking of 9-ball with the diamond-shaped rack, where the only
requirement is that the one-ball is up front.

Cool! You got the idea! I was affraid nobody would get it (I might have not
been able to send the message) but you did :))

I've had some second thoughts about the beta testers (because they are all
pov users ) but decided to include them anyway (priceless people).

Yes, with nice, rapid but smooth camera zoomout to finally show whole table.
Perhaps with white POV-Ray ball guilty for movement in other applications ;-)

You are both famous already without your funny lonely beer meetings :-)

It's a very old idea, actually. 

The only thing I haven't seen before is the use of interior_texture to
fight the transparent edge problem. This of course does not mean that
no one has come up with the same idea before, nor that no one would
have at some point had I not come up with it first.

It is certainly not a new idea. I know I've tried it as far back as
1997, though back then halos had a problem with blobs which I couldn't
solve so I had to resolve to cheating :) In more recent times, someone
(Fabien? I might be wrong though) started a subsurface scattering hype
with an image of a glass full of milk. Even more recently, it has been
applied to Poser models (two names I associate with this one are Tim
Nikias and Gilles Tran, but again, I might be wrong) to improve the
realism of the skin.

Of course, I wouldn't mind if you gave me some credit if you reuse the
technique, esp. if you borrow the source that I will post these days
:)

I used a scanned photo of a professional set to sample the colors I
used to build up the image maps, so it might as well have gone wrong
somewhere. I do remember well that at least the pool club near my
place in Sofia has that poisonous orange color for the 1 ball.

I didn't know that. I copied the arrangement from the photo I
mentioned, though from what I saw on the 'net, you seem to be right.

No, I only play 8-ball.

Oh yeah? Aren't you missing something essential, such as the "rich"
part? :)

And it was a pizza meeting, not a beer one.

No way. Someone has to be the short cue then, and I don't think anyone
would want that.

It is surely not trivial, the movement luckily is 2-dimensional in most
cases which makes things somewhat nicer but the balls don't always roll
perfectly (meaning that their angular velovity is directly related to
their translational velocity). Both the shot as well as collisions lead to
more complicated movements including gliding.

If that's guaranteed i would surely start right away...

What do you know, with the right incentive one can get *everyone* to
work.

Maybe I should try to get an MBA after all :)

Are we talking about the same thing?  The triangle thing that corrals all 
the balls at the start of the game?

Oh, that's just, well, the triangle. The rack is the little shelf-like
that holds the cues.
