Your own Textures

1) If declared as a "color ..." ----> use it in the "pigment{color...}" statement!
If a texture component i.e. "Scarlet" is defined as a "color{ ... }", we must invoke it
also as a "color" in the "pigment"-statement:
texture{ pigment{ color Scarlet }
finish { diffuse 0.9 phong 1}
} // ------ end of texture ----- |
If using Intel computers we should add here also "finish" like above, otherwise the color pattern may appear too dark!
2) If declared as a "pigment{ ... }" ---> use it in the "pigment{ ... }" statement!
If a texture component i.e. "Jade" is declared as a "pigment{ ... }", we must invoke it
also as a "pigment":
texture{ pigment{ Jade }
finish { diffuse 0.9 phong 1 }
} // ------- end of texture ----- |
Here "phong 1.0" produces a highlight, which let appear specially rounded shapes like beeing polished!
3) If declared as a complete "texture{ ... }" ---> use it in the "texture{ .. }"-statement!
If a surface property like i.e. "Polished_Chrome" oder "Glass3" is declared with all components, we only
have to write:
texture{ Glass3 } // ------- end of texture |
Naturally we can add some additional properties to a complete texture like roghness ("normal") and
quick rendering color ("quick_color") - but be carfully - use the correct syntax !!! - otherwise some unwanted effects will appear!
Example:
texture{ Glass3
pigment{ quick_color Cyan }
normal { ripples 0.5 scale 0.05 }
} // ---- end of texture ------------ |
interior{ I_Glass }
// this makes refraction activ! |
Examples for the using of
a) ready-made texture
sphere{ <0,0,0>,1
texture{ Polished_Chrome // <--- ready-made texture
pigment{quick_color White}
normal {bumps 0.5 scale 0.05}
} // ------ end of texture
} //---------------- end of sphere ---------------------- |
b) ready-made pigment
sphere{ <0,0,0>,1
texture{ pigment{ Bright_Blue_Sky //<- ready-made pigment
quick_color Blue }
normal {bumps 0.5 scale 0.05}
finish {ambient 0.1 diffuse 0.9}
}// ------- end of texture
} //---------------- end of sphere ---------------------- |
c) ready-made color
sphere{ <0,0,0>,1
texture{ pigment{color White} // <--- ready-made color
normal {bumps 0.5 scale 0.05}
finish {ambient 0.1 diffuse 0.9}
}// -------- end of textureg
} //---------------- end of sphere ---------------------- |
