pigments.inc, Include file by Samuel Benge (MMartin164@aol.com), 1999

__________
Description:
This include file adds all-new pigment types for the superpatch version of povray 3.1. They can be used with
any object.

__________
Requirements:
Superpatch 3.1 (special version of povray available at www.twysted.net)

__________
Instructions:
Place the .inc file into the include folder within the pov folder. Follow pov's documentation on how to
use inc files if necessary.

__________
Syntax:
All pigments start with a "p." All normals start with a "n." All macros start with a "m."

**Example: p_organic for an organic pigment; n_organic for a normal; m_organic for a pigment macro

Not all pigments have a macro. Macro pigments may be added to either a pigment or a normal statement
without change in name. Specific intructions for macro pigments will be given later.

To add a pigment to an object simply follow this as a guide:

sphere{<0,0,0>,2 pigment{p_organic} normal{n_organic} }
or
sphere{<0,0,0>,2 pigment{m_organic(macro items)} normal{m_organic(macro items)} }

Simple huh? You just add the pigment into where you would normally add one, just like a standard povray
texture.

List of pigments in no particular order:

p_sine_1 and n_sine_1		Like gradient y, but with a sine wave affecting the x-axis.

p_sine_2 and n_sine_2		Like sine 1, but with noise added.

m_sine(noise amount)		Like sine 1, but by adding a number in the required brackets, you can
					change the amount of noise.

p_checker and n_checker		Like the basic checker pattern, but with a color variation inside the
					squares (this pattern disintegrates if used on flat, zero-positioned
					surfaces, such as plane(y,0)).

p_organic and n_organic		A really organic looking pigment. Try it!

m_organic(distortion amount)	Like the before mentioned organic pigment, but the user can easily
					define the amount of distortion added.

p_strata and n_strata		Like gradient y, but the layers appear randomly, not uniform.

m_strata(num layers,noise)	Like the other strata, but the user can define the amount of randomly
					placed layers and amount of noise to add. Makes nice sandstone-type pigments.

p_weave and n_weave		A weave or fabric type of pigment. Strands run in all three directions (x,y,z).

p_microbes and n_microbes	A strange random-yet-uniform pigment (this pattern disintegrates if
					used on flat, zero-positioned surfaces).

p_blocks_1 and n_blocks_1	Ornate blocks the size of one unit on each side.

p_blocks_2 and n_blocks_2	Ornate blocks with distortion added.

p_diamond and n_diamond		Octahedral (diamond) shape radiating from center.

p_box and n_box			Box shape radiating from center. Makes 8 perfect hexagons when applied to
					a sphere.
