hex is a Go implementation of hexagonal grid math based on amitp’s Hexagonal Grids articles. This package focuses on hexagonal grid math, including:

• Generating sets of hexes programmatically in common patterns.
• Compositing sets of hexes with unions, intersections, and subtractions (constructive solid geometry).
• Multithreaded A* pathing in a hex grid.
• Fast intersection testing.
• Super naive drawing package! This isn’t performant; it’s to help you visualize what’s going on.

    // Base library
    "github.com/erinpentecost/hex"
    // For pathfinding
    "github.com/erinpentecost/hex/path"
    // For constructive solid geometry
