Generative art library

Project description


Generative art and graphing library for creating images and animations.

Version 3.0 notes

Version 3 introduces a few breaking changes compared to 2.x, mainly to improve the graph module.

  • The Axes class has changed. The main breaking change is that it now uses the current user coordinates to control line thickness and text size, just like most other classes. Previously it used a crazy system of guesswork and magic scaling factors. On the plus side, it now also allows much more control over the axes appearance.
  • The previous graph plotting functions have gone. Plotting is now done by a Plot class, that works in a similar way to other shape classes.
  • A minor change is that the color parameter has been renamed to pattern in most places, to reflect the fact that it can now be a gradient (and hopefully soon image, vector pattern and mesh fills will be supported). This will only affect code that uses a named parameter for color. The parameter itself can still accept Color objects, as well as the new LinearGradient objects.


generativepy is a library rather an application. It provides useful functions and example code that allow you to create images and videos by writing simple Python scripts.

The library uses pycairo for drawing graphics.

Main functionality:

  • A simple framework for creating images, image sequences, and gifs, using pycairo.
  • Support for bitmap processing using PIL and NumPy.
  • Colour module that supports RGB, HSL and CSS colours, transparency, lerping, colormaps.
  • A simple tweening module to help with animation.
  • Geometry module for drawing shapes.
  • A graphing library for plotting 2D functions.
  • 3D geometry module using moderngl.
