Math.Geometry.Grid.Octagonal

Description

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.

Synopsis

# Unbounded grid with octagonal tiles

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

# Rectangular grid with octagonal tiles

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 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 Source

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 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.
