The first matrix scales the part for a seam width.
The second orients the part to your cad file.
The last three numbers in the scond matrix are the location.
povray rotates around world 0,0,0.
so take your lines from this:
object {
_3003_dot_dat
matrix <1-SW/40,0,0,0,1-SW/28,0,0,0,1-SW/40,0,SW/2.8,0>
matrix <1,0,0,0,1,0,0,0,1,20,-24,0>
#if (version >= 3.1) material #else texture #end { Color15 }
}
change to this:
object {
_3003_dot_dat
matrix <1-SW/40,0,0,0,1-SW/28,0,0,0,1-SW/40,0,SW/2.8,0>
matrix <1,0,0,0,1,0,0,0,1,0,0,0>
translate<20,-24,0>
#if (version >= 3.1) material #else texture #end { Color15 }
}
Will give the same result.
now add rotations:
object {
_3003_dot_dat
matrix <1-SW/40,0,0,0,1-SW/28,0,0,0,1-SW/40,0,SW/2.8,0>
matrix <1,0,0,0,1,0,0,0,1,0,0,0>
rotate <0,90,0>
translate<20,-24,0>
#if (version >= 3.1) material #else texture #end { Color15 }
}
All done. Good luck.

| (...) The first 'matrix' specifies the *size* of the brick (depending on the Seam Width setting). The second one defines the rotation and translation of the brick. The first nine numbers are the rotation matrix, and the last three are the (...) (21 years ago, 8-Mar-04, to lugnet.cad)
