Library for drawing spirographs in Python

Project description

spyrograph: elegant mathematics and geometries

Animation of three geometric, symmetrical shapes being drawn next to one another left to right. The shape on the left is red, the middle green, and the right is blue.

What is it?

spyrograph is a lightweight Python package that provides an expressive and flexible set of tools for drawing beautiful mathematically driven art. With just a few lines of easy-to-read code you can start analyzing, visualizing, and exploring elegant mathematics

:computer: Installation

pip

Install the latest stable release from PyPI using

$ pip3 install spyrograph

or clone the development version from GitHub with

$ git clone https://github.com/chris-greening/spyrograph.git

:seedling: Quickstart

spyrograph is designed to be expressive and easy-to-use - simply import spyrograph and jump right into drawing elegant, complex shapes in just a few lines of code!

from spyrograph import Hypotrochoid

# Trace a hypotrochoid from 0 to 2pi where
# the fixed circle radius is 300, rolling circle 
# radius is 200, and the distance from the rolling 
# circle is 100
hypotrochoid = Hypotrochoid(
    R=300,
    r=200,
    d=100,
    thetas=np.arange(0, 2*np.pi, .1)
)
hypotrochoid.trace(
    show_circles=True, 
    frame_pause=.05, 
    circle_color="grey"
)
