Math.Geometry.Grid.Octagonal

A regular arrangement of octagonal tiles. Octagons won't tile a regular plane (there will be diamond-shaped gaps between the tiles), but they will tile a hyperbolic plane. (Alternatively, you can think of these as squares on a board game where diagonal moves are allowed.) The userguide, with illustrations, is available at https://github.com/mhwombat/grid/wiki. Also see Math.Geometry.Grid for examples of how to use this class.

Unbounded grid with octagonal tiles

Rectangular grid with octagonal tiles

data RectOctGrid

A rectangular grid with octagonal tiles. The grid and its indexing scheme are illustrated in the user guide, available at https://github.com/mhwombat/grid/wiki.

rectOctGrid :: Int -> Int -> RectOctGrid

rectOctGrid r c produces a rectangular grid with r rows and c columns, using octagonal tiles. If r and c are both nonnegative, the resulting grid will have r*c tiles. Otherwise, the resulting grid will be null and the list of indices will be null.

Toroidal grid with octagonal tiles

data TorOctGrid

A toroidal grid with octagonal tiles. The grid and its indexing scheme are illustrated in the user guide, available at https://github.com/mhwombat/grid/wiki.

torOctGrid :: Int -> Int -> TorOctGrid

torOctGrid r c returns a toroidal grid with r rows and c columns, using octagonal tiles. If r and c are both nonnegative, the resulting grid will have r*c tiles. Otherwise, the resulting grid will be null and the list of indices will be null.
