Truck - 4. Tractor with Tailer

Objects: "Round_Box", "cylinder".
Methods: "difference", "intersection", "union", "#declare" "#macro".

An include file to use this object as a read-made object
you can find at my POV-Ray Objects page.

Construction of the Trailer: We buildt the tailer by a "Round_Box" and the double axes like we used with the tractor.

The Complete Tuck: Tractor + Trailer.

The assembly was made with "macro" objects, to keep in free choice the front wheel angle, the angle of the trailer as well as the texture of the car body.

//------------------------------------
#declare Trailer_Angle    =0;//~+/-110
#declare Front_Wheel_Angle=0;//~ +/-60
#declare Truck_Texture =
   texture{ pigment{ color rgb<1,1,1>}
            finish{ diffuse .9 phong 1}
          } // end of texture
//------------------------------------
object{ Truck0( Front_Wheel_Angle,
                Trailer_Angle,
                Truck_Texture
              ) //--------------------
rotate<0,0,0>
translate<4.20,0,0>
