Oktagon / 8-Eck

Die Konstruktion eines Achtecks (Schraubenmutter oder Säulenprofil).

Objekte:    "box", "cylinder".
Methoden: "intersection", "inverse"

//====================== 8-Eck ===================
intersection{
  box {<-1, 0.0,-1>,< 1,1.0,1> rotate<0, 0,0> }
  box {<-1,-0.1,-1>,< 1,1.1,1> rotate<0,45,0> }
  scale <1,0.5,1> 
  texture{Polished_Brass 
          normal{bumps 0.3 scale 0.02}
          finish{ambient 0.1 diffuse 0.9 phong 1}
         }
  translate<1.1,0.00,0>}
//====================== 8-Eck hohl ==============
intersection{
  box {<-1, 0.0,-1>,< 1,1.0,1> rotate<0, 0,0> }
  box {<-1,-0.1,-1>,< 1,1.1,1> rotate<0,45,0> }
  cylinder{<0,-0.1,0>,<0,1.1,0>,0.5 inverse
  scale <1,0.5,1> 
  texture{Polished_Chrome 
          normal{bumps 0.3 scale 0.2}
          finish{ambient 0.1 diffuse 0.9 phong 1}
         }
