Rocket 2
Un exemple pour usage de la commande "union" et " #declare"
Objets:  sphere, cone, prism.
Méthodes: union, #declare.

//----- building an engine -------
#declare Engine =
union{
 cone{<0,0,0>,0.5,
      <0,1.5,0>,0.25
        scale<1,1,0.7>
        translate<0,0.5,0>
      texture{Chrome_Metal}}
 prism { -0.01 ,0.01 , 4
        <0.0,0.0>,<0.8,0>,
        <0.0,1.5>,<0.0,0>
        rotate<-90,0,0>
        translate<0,0.5,0>
      texture{pigment{color White }
              finish{ diffuse 0.9
                      phong 1}
             }
 }// end of prism
 difference{
  cone{<0, 0.10,0>,0.28,
       <0,0.50,0>,0.10}
  cone{<0, 0.09,0>,0.17,
       <0,0.49,0>,0.09}
  translate<0.22,0,0>
  texture{Chrome_Metal}}
// all together somewhat excentric!
translate<0.25,0,0>}
//------ building  the rocket -----
#declare Rocket = union{//4 engines
object{Engine rotate<0,  0,0>}
object{Engine rotate<0, 90,0>}
object{Engine rotate<0,180,0>}
object{Engine rotate<0,270,0>}
//----- the body ------------------
cylinder{<0,0,0>,<0,5,0>,0.5
         translate<0,0.5,0>
         texture{
          pigment{color White}
          finish {diffuse 0.9
                  phong 1}}}
// ----- with some details --------
cylinder{<0,0,0>,<0,0.1,0>,0.50
         translate<0,2.0,0>
         texture{Chrome_Metal}}
cylinder{<0,0,0>,<0,0.1,0>,0.50
         translate<0,3.5,0>
         texture{Chrome_Metal}}
cylinder{<0,0,0>,<0,0.1,0>,0.50
         translate<0,5.25,0>
          texture{Chrome_Metal}}
//------- the top part ------------
cone {<0,0,0>,0.5,<0,1.5,0>,0.25
         translate<0,5.5,0>
          texture{Chrome_Metal}}
//--- the nose on top of the rocket
sphere {<0,0,0>,0.25 scale<1,1.5,1>
       translate<0,5.0+1.5+0.5,0>
       texture{Chrome_Metal}}
}//--end of union -----------------

//------------ ready for take off:
object{ Rocket
        rotate<0,0,0>
        translate<0,0,0> }
//----------------------------- end
