Description

This packing application places a set of 2D polygonal shapes into a rectangular container which is made as small as possible for a given computation time.

  • Input: a set of polygonal pieces (wooden puzzle, cloth patterns, metal, etc.)
  • Output: a list of translations and rotations for each piece + the size of the final rectangular container, where the container size has been minimized
  • Real-world application: sprite packing in games, cutting patterns in cloth, etc.
