Polyline
Similar to polygon, but using the absolute value of the winding number instead of odd-even filling.
Syntax
polyline { \(Px [,]\)\{3,n\} range { \(<low,high>\)\{1,m\} } OBJECT_MODIFIERS }
n coplanars points Px
<low,high> specification of interval for winding number
Winding number
#declare A=<0,3,0>;
#declare B=<6,3,0>;
#declare C=<4.5,1,0>;
#declare D=<7,2,0>;
#declare E=<4.5,6,0>;
#declare F=<7,4,0>;
#declare G=<2,4,0>;
#declare H=<4,6,0>;
#declare I=<4,0,0>;
#declare J=<5,0,0>;
#declare K=<5,8,0>;
