"three-dimensional solid texturing" with prozedural 3d textures
|
Instead of a single color like "color Red",
we can use also a color pattern with the "pigment" statement.
Besides of the ready made color patterns like Jade, Bright_Blue_Sky, Blood_Sky,
Candy_Cane, Red_Marble, Brown_Agate, Cork etc., we can also
use a bundle of regular patterns (like checker, brick, spiral etc.) and
an infinite variety of irregular and floating patterns
by using a pattern type like "gradient<0,1,0>" and
a list of color or pigments to be used listed in a so-called "color_map"
or "pigment_map".
We also can use a pattern with a "texture_map" or a "normal_map".
Most of them work for "normal" as well as for colors.
These patterns were not only pasted on the surface of a geometric
object or wrapped around a shape like a wallpaper. They are
are three dimensional structures like the veins in a marble cake or in wood!
This method is called "three-dimensional solid texturing". The patterns
were produced by 3dimensional functions (apart from material_map, image_map and bump_map)
and this is why these textures are called processurale textures. Every point in
the 3d space has his own pattern property. If such a texture is applied to a shape
it's like cuting out a piece of marble cake. We can also scale, rotate, translate
them inside the "pigment" or "texture" bracket.
Turbulence brings live to the colors:
With the additional statement turbulence and values between
0.00 and 1.00 or more we modify each pattern. The attributes of pigment / normal
are variable. By this we can get nearly each kind of natural pattern structure,
like clouds, wood or marble.

for "pigment" und "normal"
Here an example for "crackle":
// ground ----------------------------------------------------
plane{<0,1,0>, 0
texture{Polished_Chrome
pigment{ color rgb<1,0.8,0>}
normal { crackle 0.75 turbulence 0.25 scale 0.25}
finish { diffuse 0.9}}
}// end of plane
//------------------------------------------------------------ |
For the texture of the above sphere see here:
layered textures
The following example is also know as "Bright_Blue_Sky" -
sphere{<0,0,0>,1 translate<-1,1,0>
texture{
pigment{
bozo turbulence 0.56
color_map {
[0.0 color rgb <0.5, 0.5, 1.0>] //LightBlue
[0.5 color rgb <0.5, 0.5, 1.0>] //LightBlue
[0.6 color rgb <1.0, 1.0, 1.0>] //White
[1.0 color rgb <0.5, 0.5, 0.5>] //Grey
} // end of color_map
} // end of pigment
finish { diffuse 0.9 phong 1}}}
// end of finish, end of texture, end of sphere |
sphere{<0,0,0>,1 translate<1,1,0>
texture{
pigment{
ripples scale 0.5 turbulence 1.5
color_map {
[0.0 color NeonPink ]
[0.1 color NeonPink ]
[0.5 color Yellow ]
[0.6 color White ]
[1.0 color Gray50 ]
} // end of color_map
} // end of pigment
normal { wrinkles 0.75 scale 0.1}
finish { diffuse 0.9 phong 1}}} |
