Hexagonal tiling

This program illustrates the progress of an algorithm I developed to compute Field of View (FOV) within a hexagonal grid. View is computed from the centre of a hexagon, and expands outward in discrete steps (by pressing the "Expand" button). The grid contains some obstacles (darkened hexagons) which block view through them.
Hex Grid Algorithm Testbed
Tactical affairs such as movement are best handled on a grid, but the grid need not be a bunch of squares. This variant replaces the squares with hexagons. (Hex grid paper and mats are available at many hobby stores.) The primary advantage of this variant is that it eliminates the “every other square counts double” rule for diagonal movement, because it eliminates diagonal movement. Characters simply move from hex to adjacent hex, changing direction as they like.

Hexagonal tiling - Wikipedia, the free encyclopedia
In geometry , the hexagonal tiling is a regular tiling of the Euclidean plane , in which three hexagons meet at each vertex. It has Schläfli symbol of {6,3} or t{3,6} (as a truncated triangular tiling). Conway calls it a hextille . The internal angle of the hexagon is 120 degrees so three hexagons at a point make a full 360 degrees. It is one of three regular tilings of the plane . The other two are the triangular tiling and the square tiling .
A hex map , hex board or hex grid is a gameboard design commonly used in wargames of all scales. The map is subdivided into small regular hexagons of identical size. [ edit ] Advantages and disadvantages The primary advantage of a hex map over a traditional square grid map is that the distance between the center of each hex cell (or hex ) and the center of all six adjacent hexes is constant. By comparison, in a square grid map, the distance from the center of each square cell to the center of the four diagonal adjacent cells it shares a corner with is greater than the distance to the center of the four adjacent cells it shares an edge with. The constant distance of a hex map is desirable for games in which the measurement of movement is a factor.
