Door

The Construction of a Door by "macro".

Objects: "box"
Methods: "difference", "union", "declare" "macro"

The construction in details:

The door is constructed in a similar way to the "Window". It's made as a macro to let the door open angle be free to choose.

#macro Door (Door_Angle) 
union{  // I
 difference{
  box{<-0.50,0.01,-0.02>,< 0.50,1.80,0.02>}
  box{<-0.45,0.85,-0.03>,<-0.03,1.27,0.03>}
  box{< 0.03,0.85,-0.03>,< 0.45,1.27,0.03>}
  box{<-0.45,1.33,-0.03>,<-0.03,1.75,0.03>}
  box{< 0.03,1.33,-0.03>,< 0.45,1.75,0.03>}
  texture{Door_Texture_1}
  } // ---end of difference 
 box{ <-0.49,0.81,0.0>,< 0.49,1.79,0.001>
      texture{T_Glass3}}  // no interior!!!
 // door handle
 union{ // II
  sphere  {<-0.15,0,-0.07>, 0.015 }
  cylinder{<-0.15,0,-0.07>,<0,0,-0.10>,0.015}
  sphere  {< 0,0,-0.07>, 0.015}
  cylinder{< 0,0,-0.07 >,<0,0,0>, 0.015}
  cylinder{< 0,0,-0.035>,<0,0,0>, 0.04}
  texture { Chrome_Metal
            finish {ambient 0.1 diffuse 0.9}}
  translate<0.43,0.75,0>
  }// end of union II
 
 // rotation of the door:
 translate< 0.50,0,0> 
 rotate<0,-Door_Angle,0>
 translate<-0.50,0,0> 
 } // ---end of union I
#end // ------------ end of Door(...) macro

#declare Door_Hole =   //symmetric!!!
  box{<-0.50,0.01,-0.50>,< 0.50,1.80,0.50>
      texture{Wall_Texture_2}}
//--------- end of Door_Hole ---------------
A door with windows and handle.

To place the doors in their position we have to define their positions. Then we can subtract the door holes from the wall and add doors to their positions.


#declare Door_Positon_1 = <-1,0,0>;
#declare Door_Positon_1 = < 1,0,0>;

difference{
box   { <-2,0,0>,< 2,2.3,0.2>   
        texture {Wall_Texture_1}}
object{ Door_Hole translate Door_Positon_a}
object{ Door_Hole translate Door_Positon_b}
} // end of difference --------------------

object{ Door(85) translate Door_Positon_1}
object{ Door(25) scale<-1,1,1>
                 translate Door_Positon_2}
//-----------------------------------------
