Library for creating generative art and maths animations

generativepy

Generative art and graphing library for creating images and animations.

Version 23.11 notes

3D drawing is likely to change in a future release. The rest of the library is reasonably stable.

• Switched to date based versioning
• Add parametric plots to the graph module
• Allow The Turtle class to accept a list of colours, and cycle through the list as the turtle draws a path.
• Update geometry.Transform class to use generativepy matrix order rather than PyCairo matrix order.
• Add unit matrix to math module

Usage

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 requires:

• pycairo.
• NumPy.
• Pillow.
• easy_vector.
• moderngl (only required for 3D imaging).
• MoviePy
• Command line application gifsicle (only needed for GIF creation).
• Commandline applications latex and divpng

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.
• MovieBuilder supports creating video files from separate scenes.
• Latex formula rendering
• 3D geometry module using moderngl.
• Math modules for vectors, matrices and abstract shapes.
