Edge of a Voronoi diagram Internal id of the element. Assigned color of the receiver. cell the edge belongs to Begin and End voronoi vertex CCW next edge within voronoi cell CCW previous edge within voronoi cell Rotated CCW next edge within voronoi cell Rotated CCW previous edge within voronoi cell Twin edge Returns true if both vertices are finite Returns true if the end vertex is infinite Returns true if edge is straight Returns true if edge is curved Returns false if edge goes through endpoint of the segment site Returns true if edge goes through endpoint of the segment site Returns true if the point is on the segment Returns a shape for the edge Returns the distance of the vertices to the input source Returns the angle (in degree) of the segments if the edge was formed by two segments
