# 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!
|
|
|
|

## Installation
|
|
|
|
### System Requirements
|
|
- **Required**
|
|
- [Lua](https://lua.org/)
|
|
- **Optional**
|
|
- [OpenSCAD](http://www.openscad.org/): for creating STL files and viewing generated .scad files
|
|
- [Blender](https://www.blender.org/): a great tool for importing generated STL files and having some fun rendering them
|
|
|
|
### Setup
|
|
Clone this repository:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
# 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:
|
|
|
|
```bash
|
|
./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
