    BlockFractal

    Dependencies Node.js CI License

    Generates a blocky fractal-like shape, like a tile-based randomized koch curve

    See the demo

    Example Result

    Installation

    npm install block-fractal
    

    Usage

    Create a block fractal:

    const BlockFractal = require('block-fractal');
    
    const path = BlockFractal.makeBlockFractal({
        iterations: 7
    });

    Convert the path into a set of raster lines (makes cell tests faster):

    const mask = path.rasterize();

    Test if a tile is in the shape:

    const inside = mask.get(x, y);

    ...

    Details

    BlockFractal starts with a "seed" shape, which by default is a 2x2 square:

    Example 1

    The shape is doubled, and then each edge is either left in place or moved to one side or the other:

    Example 10

    The result is a new, bigger shape, similar to the previous shape but with a more varied border:

    Example 13

    That process is then repeated as many times as requested.
