Yes. I'm currently rendering a scene with those ;)

But as I'm using high quality radiosity settings (and no light sources) 
I guess the render time will be the same as at the time when I had 
originally written the scene and rendered it on something like a 200 MHz 
Pentium machine IIRC.

You know that I am quite jealous of you, Lego generation kids? :)

Well, there it is. Good nostalgic work, Ive!

Only one problem. If the dog was peeing on the tree, shouldn't it be his 
OTHER leg in the air ??

Great rendering!

I've been doing some Lego rendering recently - see 
http://www.pearse.co.uk/lego for my recent experiments.

I've only used the basic PoseRay settings for rendering so far but I 
would love to create some more realistic renders. Any chance you could 
post some code or hints on lighting / radiosity settings?

Thanks in advance

I'm not using LDraw just an very old include file of mine where only the
very basic bricks (the ones I actually did have) are defined. Also the
scene is an old one and I just used higher quality settings for 
area_lights and focal_blur for this contemporary rendering as meanwhile 
I have something faster than a 200 MHz Pentium  ;)


The used finish for the bricks is:

#declare LegoFinish = finish {
     ambient 0  diffuse 0.775
     specular 0.6  roughness 0.012
     reflection  {0.01 0.125 falloff 2} conserve_energy
}


and for "glass" bricks

#declare LegoTransFinish = finish {
     ambient 0  diffuse 0.5
     specular 0.6  roughness 0.012
     reflection  {0 1 fresnel on}  conserve_energy
}


I have only defined the basic colors (again the ones I actually did 
have) and the values are taken from
http://www.peeron.com/cgi-bin/invcgis/colorguide.cgi
but are inverse gamma corrected to have them in linear color space as
they should be:

#macro GI(C)
   #local C = color C;
   <pow(C.red/255, 2.2),
    pow(C.green/255, 2.2),
    pow(C.blue/255, 2.2),
    C.filter>
#end


#declare LegoBlack  = GI(<  31,  45,  52, 0 >);//No.26 Black
#declare LegoWhite  = GI(< 240, 241, 240, 0 >);//No. 1 White
#declare LegoGrey   = GI(< 161, 165, 162, 0 >);//No. 2 Gray
#declare LegoRed    = GI(< 196,  40,  27, 0 >);//No.21 Bright Red
#declare LegoGreen  = GI(<  75, 151,  74, 0 >);//No.37 Bright Green
#declare LegoBlue   = GI(<  13, 105, 171, 0 >);//No.23 Bright Blue
#declare LegoYellow = GI(< 245, 205,  47, 0 >);//No.24 Bright Yellow
#declare LegoGlass  = GI(< 235, 240, 241, 0.885 >);


The lighting is just very basic (again it is an old scene) just 2 
area_light and a shadowless fill-light positioned exactly at the camera 
position.

And of course assumed_gamma has to be 1.0 for POV-Ray versions prior 3.7 
and has to be removed for the 3.7 beta versions.

I figured that there would be no interest for my "old-school" Lego 
include file where just the basic bricks and the old wheels are defined. 
If there is some interest I could prepare it for download and add the 
scene file for the shown image as usage example.
But as I would have to clean it up a bit and add a few comments it might 
take a few days, just tell me.

I know, but I think no one would have recognized it with the other leg 
raised without rearranging the whole scene - and I was too lazy for 
doing THIS.
In fact I'm quite surprised that everyone seems to see a dog in the 
object made of just 7 basic bricks. Well it is indeed meant to be one as 
the comment within this old scene file shows, but still...

(Note to myself: play more around with a higher level of abstraction and 
leave the photo-realistic path for a while!)

Well, I'm 72.  So Legos were much later than my early years.  For me it was Tinker
Toys (all 
wood), then a little later, Erector Sets (all metal).

Of course, now we can build anything with POVRay...     ;-)

Hi Ive:

   Very nice... as usual. Specially the transparent blocks are awesome,
perhaps due to the subtle chromatic aberration. And indeed nostalgic... I
seem to remember playing with these, although my childhood memories are
mostly gone.

When I got my first Lego set in 1974, the tyres were black, not gray... 
and also later, I never encountered any gray tyres! Could it be that 
Lego sets with gray tyres were only marketed in the US?

See you in Khyberspace!
