BTW:

tiling pattern 1-24 = LeForgeron
tiling pattern 25-27 = clipka

Thank you indeed, Jaime. Very nice and useful little job.

Is there a particular reason why the rendered tile is rectangular? Would 
it not make (more) sense if the tile was square?

   Yeah... crackle is also a good base.

   Well, already repeating patterns are the best, of course. Also, you
can get ride of the random rotation, and use instead a fixed amount, to
line up the image patterns with the tiling pattern: it should give you
more chances to get a result without obvious seams.

   Another way I've just found, is to apply successive repeat warps
combined with 120 degree rotations, "a la stbenge":

#declare t_base=
texture{
     pigment{
       image_map{jpeg imagemap interpolate 2}
       rotate 90*x
       translate rand(r_pattern)*x
       translate rand(r_pattern)*z
       rotate 360*rand(r_pattern)*y
       scale im_scale
       #local nCount = 0;
       #while ( nCount < 360/120 )
         rotate 120*y
         warp { repeat .5*x flip x}
         warp { repeat sqrt(.75)*z flip z}
         #local nCount = nCount + 1;
       #end
     }
     finish{emission 1}
}

   This limits a bit the variety of the results, but you get ride of the
visible seams.

   Oops! Many thanks to LeForgeron then... sorry for the confusion. :(

   As trial&error is my most usual approach to geometry, I first tried
square repeats, but it did not work. Then I noticed the tiling type five
is not square, so I then applied good & old Pythagoras to get the
correct ratio. I really don't know if it can be made square, or if it
makes more sense... I just assumed it should be that way for this
specific symmetry. And for my wallpapering usage, if it tiles
seamlessly, that's enough. But I guess you're already thinking on the
Gancaloon ceramic tiles... ;)

That makes sense indeed. If the tiling type is not square, the image 
should not be either :-)  I missed that part indeed.

This macro makes a nice addition to your azulejos macro which I used 
(and shall use again) in Gancaloon. The possibilities are endless.

Jamie,

Thanks for the #macro (sent my latest project in a different direction!) 
... easy to use, just scaling and orientation for my situation.

   Very nice! ... but now it's asking for some wall lamps. :)

Yes, and preferably gaslight too ;-)

You're "blaming" the wrong person this time: I'm not responsible for 
/some/ of the new features :-) All the tiling patterns available in 
3.7.RC3 were added by Le_Forgeron instead. I merely added three more to 
the set, to be included in RC4.
