Maze generator

Generate mazes of different shapes and arbitrary sizes Maze types

Maze generator can create rectangular, hexagonal, honeycomb and circular mazes. Maze generation can be done using Kruskal's algorithm, depth-first search, breadth-first search, loop-erased random walk or Prim's algorithm. Mazes can be rendered in svg or png format (using gnuplot as intermediate in the latter case).

Dependencies

Maze generator uses gnuplot (with a system call gnuplot) to render png mazes. So make sure that gnuplot 5.0+ is installed with pngcairo terminal support and is in the path if you wish to use png.

The code is written in C++ 11, you will need a not-too-ancient C++ compiler to build it.

Installation

cd src; make

Usage

Usage: mazegen [--help] [-m <maze type>] [-a <algorithm type>]
               [-s <size> | -w <width> -h <height>]
               [-t <output type] [-o <output prefix>]

Optional arguments
  --help  Show this message and exit
  -m      Maze type
          0: Rectangular (default)
          1: Hexagonal (triangular lattice)
          2: Honeycomb
          3: Circular
          4: Circular (triangular lattice)
          5: User-defined
  -a      Algorithm type
          0: Kruskal's algorithm (default)
          1: Depth-first search
          2: Breadth-first search
          3: Loop-erased random walk
          4: Prim's algorithm
  -s      Size (non-rectangular mazes, default: 20)
  -w,-h   Width and height (rectangular maze, default: 20)
  -t      Output type
          0: svg output (default)
          1: png output using gnuplot (.plt) intermediate 
  -o      Prefix for .svg, .plt and .png outputs (default: maze)

Issues

The arcs in the circular mazes are plotted as parametric curves in gnuplot, and png can take quite long to render for large mazes.
