Hexagons for C++

HEX

Hexagonal grids for C++

This library provides only hexagon related computations and is renderer agnostic. The examples below have been rendered using Cinder.

Creation, addition & subtraction

l = hex::layout::hexagonal(6);

l -= hex::layout::hexagonal(3);

l += hex::layout::parallelogram(10, 10, layout::options::vertical);

l += hex::layout::parallelogram(10, 10, layout::options::standard);

l -= hex::layout::hexagonal(3);

l += hex::layout::hexagonal(1);

Coordinate space conversions

vec2 v = vec2(e.getPos()) - getWindowCenter();
hex::point p(v.x, v.y);
hover = hex::lattice::point_to_cell(p, orientation, radius);
