Geometric Objects with POV-Ray 3.6 / 3.7 - objects and macros from my include file shapes3.inc

Geometric object definded in my include file "shapes3.inc" .

Round_Conic_Torus
general syntax:

object{ Round_Conic_Torus(
                         Center_Distance,
                         R_upper,
                         R_lower,
                         Border_R,
                         Merge_On
                       ) //--------------
         texture{ ... }
      } // end of object ----------------

Center_Distance =
vertical center distance of upper + lower torii,
R_upper >0, upper radius at <0,C_distance,0>.
R_lower >0, lower radius on zero.
Border_R = border radius, max. = min(R_lower,R_upper)
Merge_On 0 = union, 1 = merge.

Example scene file
".txt" or ".pov"

Example:

#include "shapes3.inc"
object{ Round_Conic_Torus(
           1.00, // >0, vertical center distance
           0.80, // >0, upper radius
           0.50, // >0, lower radius
           0.10, // border radius,
             // max. = min(lower radius, upper radius)!
           0 // Merge_On: 0 or 1
        ) // ------------------------------------
        texture{ pigment{ color rgb <1,1,1>}
                 finish { phong 0.1}
               } // end texture
        scale <1,1,1>
        rotate <0,0,0>
        translate < 0, 1, 0>
      } // end of object --------------------
