Any way you could render this first image at a higher resolution? I think I
might send it to my mother for her desktop background.

Well thanks...
As long as it all works out for you and we both learned something. I always
take these things as a challenge to teach myself how to do something and
hopefully learn something.

?

Gah, a bit of oversight on my part. Neglected to adjust the pattern for the
Ymin,Zmax,Ymax column of the uv mapping. Was looking at the wrong side of the
box when I was testing and never looked at the +z side or I wouldve noticed
right away. Hopefully this works now:

I was playin with your first one, check it out:
#declare TilSiz=<6/7,12/7,-4>; //Size of tile (x,y)
#declare scal = (1-TilSiz)*TilSiz/34.85;
#declare Grt=1/7;
#declare TQ_tile =
pigment { uv_mapping
gradient x
pigment_map{
[Grt/(TilSiz.x+Grt) rgb 1]
[Grt/(TilSiz.x+Grt) gradient y
colour_map{
[Grt/(TilSiz.y+Grt) rgb 1]
[Grt/(TilSiz.y+Grt) rgb <.6,.6,1> ]
}
]
}
//scale <scal.x,abs(scal.y),1> // = different image
scale scal // negative y-scale
//scale <1/160,1/20,1>*.7
}
echov((1-TilSiz)*TilSiz*0.0287) // <0.00351,-0.03514,-0.57400>
cr()
echov((1-TilSiz)*TilSiz/34.85) // <0.00351,-0.03514,-0.57389>
cr()
echov(<1/160,1/20,1>*.7) // = <0.00437,0.03500,0.70000>
cr()
#declare pool_box2 =
difference {
box { <-8, -66.5, -8> <232, 0, 232> } // legoworld hole +8
box { <0, -65, 0> <224, 1, 224> }
texture { TQ_tile basic_finish }
translate <-8,0,-8>
}
object { pool_box2 translate y*4 }
how/why is negative -scale is OK?

the only part that I see remaining, is to have the numbers relative to box
dimension so grout lines land on corners,
and figuring out what "34.85" or "0.0287" is or whatever it should be from
overall dimensions ... er something to that effect

Right now the numbers are relative to the box dimensions (BSiz should be input
as the size of the box to be used). I already also have the grout lines half
offset so they show up at the corners properly. The only thing you really need
to do is make sure that the box size is a multiple of the tile size. If it
isn't then you would get an incorrect corner with no grout and a partial tile.
