Hello,

Is there a function or macro to check, if a given point is inside an object ?


.....
#declare Obj =
object {
  some_complex_object
  translate ...
  rotate ...
  scale ....
  ....
}

#declare Point = <1,2,3>;

#if (inside(Point,Obj)) // ?????
.....
#end

quite literally that, except it's 'inside(obj,point)'.  :-)
