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 {ambient 0.1 diffuse 0.9 }
} // 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 {ambient 0.15 diffuse 0.85 phong 1.0 }
} // ------- 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!
Sample:
texture{ Glass3
pigment{ quick_color Cyan}
normal { ripples 0.5 scale 0.05 }
}// ----end of texture
interior{I_Glass} // this makes refraction activ!
//----------------------------------------------
Samples 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 texture
}//--- end of sphere ------------------------------- |
