Description

A regular arrangement of triangular tiles. 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 triangular tiles

data UnboundedTriGrid Source

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

Triangular grid with triangular tiles

data TriTriGrid Source

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

triTriGrid :: Int -> TriTriGrid Source

triTriGrid s returns a triangular grid with sides of length s, using triangular tiles. If s is nonnegative, the resulting grid will have s^2 tiles. Otherwise, the resulting grid will be null and the list of indices will be null.

Parallelogram-shaped grid with triangular tiles

data ParaTriGrid Source

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

paraTriGrid :: Int -> Int -> ParaTriGrid Source

paraTriGrid r c returns a grid in the shape of a parallelogram with r rows and c columns, using triangular tiles. If r and c are both nonnegative, the resulting grid will have 2*r*c tiles. Otherwise, the resulting grid will be null and the list of indices will be null.

Rectangular grid with triangular tiles

data RectTriGrid Source

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

rectTriGrid :: Int -> Int -> RectTriGrid Source

rectTriGrid r c returns a grid in the shape of a rectangle (with jagged edges) that has r rows and c columns, using triangular tiles. If r and c are both nonnegative, the resulting grid will have 2*r*c tiles. Otherwise, the resulting grid will be null and the list of indices will be null.

Toroidal grid with triangular tiles

data TorTriGrid Source

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

torTriGrid :: Int -> Int -> TorTriGrid Source

torTriGrid r c returns a toroidal grid with r rows and c columns, using triangular tiles. The indexing method is the same as for ParaTriGrid. If r and c are both nonnegative, the resulting grid will have 2*r*c tiles. Otherwise, the resulting grid will be null and the list of indices will be null.

Cylindrical grids with triangular tiles

data YCylTriGrid Source

A cylindrical grid with triangular tiles, where the cylinder is along the y-axis. The grid and its indexing scheme are illustrated in the user guide, available at https://github.com/mhwombat/grid/wiki.

yCylTriGrid :: Int -> Int -> YCylTriGrid Source

yCylTriGrid r c returns a cylindrical grid with r rows and c columns, using triangular tiles, where the cylinder is along the y-axis. The indexing method is the same as for ParaTriGrid. If r and c are both nonnegative, the resulting grid will have 2*r*c tiles. Otherwise, the resulting grid will be null and the list of indices will be null.

data XCylTriGrid Source

A cylindrical grid with triangular tiles, where the cylinder is along the x-axis. The grid and its indexing scheme are illustrated in the user guide, available at https://github.com/mhwombat/grid/wiki.

xCylTriGrid :: Int -> Int -> XCylTriGrid Source

xCylTriGrid r c returns a cylindrical grid with r rows and c columns, using triangular tiles, where the cylinder is along the y-axis. The indexing method is the same as for ParaTriGrid. If r and c are both nonnegative, the resulting grid will have 2*r*c tiles. Otherwise, the resulting grid will be null and the list of indices will be null.
