- Adding Square & Triangular pattern (with beta 40)

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.
