same my test picture
and here is my solution using repeating warps (first time for me) and layered
textures (first own by me)
code is much shorter I think
I considered repeating of rotated image
#macro TexForSander(MS,L,MC,IN)
// MC - Mortar color
// MS - Width of mortar
// L - Length of piece
// IN - Image name
#local W=(L-MS)/2; // Width of piece
#local P=2*(MS+L); // Distance of repeating
#local Img1=texture{pigment{
image_map{sys IN once}
rotate x*90
scale <W/P,1,L/P>
warp {repeat x}
warp {repeat z}
scale P
}}
#local Img2=texture{Img1 rotate y*90}
#local V=MS+W;
#local U=MS*(1+z);
texture{pigment{color rgb MC}}
texture{Img2 translate MS}
texture{Img2 translate MS+V}
texture{Img2 translate MS+2*V}
texture{Img2 translate MS+3*V}
texture{Img1 translate U+V}
texture{Img1 translate U+2*V}
texture{Img1 translate U+3*V}
texture{Img1 translate U+4*V}
#end
use it for example this way:
plane { y,0 TexForSander(0.05,1,color rgb 0,"back78.bmp") }
I worked on it with megapov but it should work with povray 3.1
