multimaze

A collection of maze generation programs

Ported back in 2015 (and since adapted) from an algorithm of my own design that was originally implemented in Python.

Now has a 3d mode!

Current blog posts about this project:

Installation

System Requirements

Required
- Lua
Optional
- OpenSCAD: for creating STL files and viewing generated .scad files
- Blender: a great tool for importing generated STL files and having some fun rendering them

Setup

Clone this repository:

git clone https://git.starbeamrainbowlabs.com/sbrl/multimaze.git
cd multimaze.lua

Usage

See the usage information for the program by calling main.lua like so:

lua main.lua help

Operating modes:

Mode	Description
`help`	Displays the help text
`maze`	Generates 2D mazes and writes them to stdout
`maze3d`	Generates 3D mazes and writes them in layers to stdout
`maze3d_openscad`	Generates 3D mazes and writes an OpenSCAD file to the specified location

To render a 2D maze as ASCII, do this:

lua main.lua maze --width 25 --height 25
# Alternatively, in shorthand:
lua main.lua maze -w 25 -h 25

To render a 3D maze as a .STL file, do this:

# Generate the OpenSCAD file
lua main.lua maze3d_openscad -w 15 -h 15 -d 17 -f 15x15x17.scad
# Convert the OpenSCAD file to an STL
openscad -o 15x15x17.stl 15x15x17.scad

Users who have sh (Bash works too) installed can use the maze wrapper script instead:

./maze maze3d_openscad -w 15 -h 15 -d 17 -f 15x15x17.scad
./maze maze -w 25 -h 25

Cookbook

Make an (almost) seamless texture

./maze maze_svg --scale 40 -w 31 -h 31 -f maze.svg
inkscape -o maze.png maze.svg
convert maze.png -crop 1080x1080+80+80 extract.png

The formula here for the crop is:

width: w * scale - (scale * 4)
height: h * scale - (scale * 4)
x offset: scale * 2
y offset: scale * 2
