http://www.cosy.sbg.ac.at/~held/projects/vroni/vroni.html http://www.cosy.sbg.ac.at/~held/projects/vroni/vroni.html when generalized to line segments, voronoi diagrams can be used to efficiently compute offset contours. Offsets are used for CNC operations, slicing 3d print models, robotic path planning etc.
