The <code>aoi</code> pattern can be used with <code>pigment</code>, <code>normal</code> and <code>texture</code> statements. The syntax is as follows:
<pre>
pigment {
aoi
pigment_map {
[0.0 MyPigmentA]
...
[1.0 MyPigmentZ]
}
}

normal {
aoi
normal_map {
[0.0 MyNormalA]
...
[1.0 MyNormalZ]
}
}

texture {
aoi
texture_map {
[0.0 MyTextureA]
...
[1.0 MyTextureZ]
}
}
</pre>
It gives a value proportional to the angle between the ray and the surface; for consistency with the slope pattern, values range from 0.5 where ray is tangent to the surface, to 1.0 where perpendicular; in practice, values below 0.5 may occur in conjunction with smooth triangles or meshes.
Note: This differs from the current MegaPOV implementation, where the values range from 0.5 down to 0.0 instead. If compatibility with MegaPOV is desired, it is recommended to mirror the gradient at 0.5, e.g.:
<pre>
pigment {
aoi
pigment_map {
[0.0 MyPigment3]
[0.2 MyPigment2]
[0.5 MyPigment1]
[0.8 MyPigment2]
[1.0 MyPigment3]
}
}
</pre>
