Square

The square pattern is a block pattern that generates a repeating pattern of squares in the x-z-plane. In this instance imagine tall rods that are square in shape and are parallel to the y-axis and grouped in bundles like shown in the example image. Four separate colors should be specified as follows:

pigment {
  square [COLOR_1 [, COLOR_2 [, COLOR_3 [, COLOR_4]]]]
  [PATTERN_MODIFIERS...]
  }

Each side of the square is one unit long. The square rods of color extend infinitely in the +y- and -y-directions. If no colors are specified then default blue, green, red and yellow colors are used.

You may also use pigment statements in place of the colors. For example:

pigment {
  square  
  pigment { Aquamarine },
  pigment { Turquoise },
  pigment { Sienna },
  pigment { SkyBlue }
}

When used with textures, the syntax is...

texture {
  square  
  texture{ T_Wood1 },
  texture{ T_Wood2 },
  texture{ T_Wood4 },
  texture{ T_Wood8 }
}

The square pattern has a default color_map built in that results in red, blue, yellow and green tiles.

This is a block pattern which cannot use wave types, color_map, or slope_map modifiers.

Triangular

The triangular pattern is a block pattern that generates a repeating pattern of triangles in the x-z-plane. In this instance imagine tall rods that are triangular in shape and are parallel to the y-axis and grouped in bundles like shown in the example image. Six separate colors should be specified as follows:

pigment {
  square [COLOR_1 [, COLOR_2 [, COLOR_3 [, COLOR_4 [, COLOR_5  [, COLOR_6]]]]]]
  [PATTERN_MODIFIERS...]
  }

Each side of the triangle is one unit long. The triangular rods of color extend infinitely in the +y- and -y-directions. If no colors are specified then default blue, green, red, magenta, cyan and yellow colors are used.

You may also use pigment statements in place of the colors. For example:

pigment { 
  triangular
  pigment { Aquamarine },
  pigment { Turquoise },
  pigment { Sienna },
  pigment { Aquamarine },
  pigment { Turquoise },
  pigment { SkyBlue }
}

When used with textures, the syntax is...

texture {
  triangular 
  texture{ T_Wood1 },
  texture{ T_Wood2 },
  texture{ T_Wood4 },
  texture{ T_Wood8 },
  texture{ T_Wood16 },
  texture{ T_Wood10 }
}

The triangular pattern has a default color_map built in that results in red, blue, cyan, magenta, yellow and green tiles.

This is a block pattern which cannot use wave types, color_map, or slope_map modifiers.

Tiling

The tiling pattern provides some very classical patterns of tiling in the x-z plane. it should be specified as follows:

pigment {
  tiling Pattern_Number
  [PATTERN_MODIFIERS...]
  }

Providing a map is strongly recommended. It can as usual be also used with texture_map in texture.

For each pattern, each tile part of the pattern have the same bevel as the other tile in the same pattern, allowing to make regular tile caulk the size you want. For a pattern with N kind of tiles, the main colour/texture of the tiles are at x/N (with x going from 0 to N-1), and the extreme colour/texture caulk for these tiles are at (x+1)/N, the bevel covering the range between these two values.

Each tiles have a side which is exactly one unit long. The tiles extend infinitely in the +y- and -y-directions. If no map is specified then default grey map is used.

There are 24 provided classical tilings:

1. single square
2. single hexagon
3. two triangle (one up, one down)
4. single rhombus
5. three rhombus of different orientations
6. two rectangles of different orientations
7. one octagon and a square
8. one square and two triangles
9. one hexagon and two triangles
10. single square with offset
11. one square and two rectangles
12. one square and two rectangles with additional mirroring
13. one square and two trapezium
14. one square and four trapezium
15. one big square and one small square
16. one hexagon, one square and one triangle
17. one hexagon, three squares and two triangles
18. two rectangles in pair
19. left version with one hexagon and two triangles
20. right version with one hexagon and two triangles
21. two squares and four triangles
22. one do-decagon and two triangles
23. one do-decagon, one hexagon and one square
24. one do-decagon, one hexagon and three square
