Procedural Contour Map Generator

This project generates a procedural contour map based on Perlin noise and exports the result as an SVG file. The map can be customized with different noise scales, contour levels, and line thicknesses.

Features

• Generate a heightmap using Perlin noise.
• Create contour lines based on the heightmap.
• Export the contour map as an SVG file.
• Use a simple progress bar to track the process.

Installation

Option One

Use the automatically generated "create.exe". no, it's not a virus it's made with a github action, see .github folder for this script

Option Two

To get started, you'll need to install the required Python dependencies. You can do this by creating a virtualenv and installing the packages from the requirements.txt file.

1. Clone this repository:

   git clone https://github.com/DogeSkii/PCMG
   cd PCMG

2. Install the dependencies:

   pip install -r requirements.txt

Usage

Once the dependencies are installed, you can generate the contour map by running the Python script.

create.py

This will generate a heightmap using Perlin noise and create contour lines at different levels. The contour map will be exported as an SVG file.

Script Configuration

You will get a prompt to ask if you would like to change any settings.

• WIDTH and HEIGHT: Set the dimensions of the generated map (default: 1024x1024).
• DEFAULT_SCALE: Controls the zoom level of the Perlin noise (default: 150.0).
• DEFAULT_OCTAVES: Controls the detail of the noise (default: 4).
• DEFAULT_CONTOUR_LEVELS: Number of contour levels to generate (default: 15).
• DEFAULT_LINE_THICKNESS: Thickness of the contour lines (default: 2).
• output_filename: The name of the output SVG file (default: contour_map.svg).

Example Output

After running the script, an SVG file (contour_map.svg) will be generated, containing contour lines that represent the heightmap.
