DColor: A Domain Coloring Python Module

What is DColor?

DColor is a Python3 module for visualizing complex-valued functions using a Domain Coloring scheme.

Requirements

DColor leverages two well-known Python libraries: Numpy and Matplotlib. Before being able to use DColor, you must install these using the following commands:

$ python3 -m pip install -U numpy

$ python3 -m pip install -U matplotlib

clone the repository

git clone https://github.com/hernanat/dcolor.git

run example

python dcolorExample.py

It generates a series of examples. When each image appears clicking the close button starts the next example. Lambda expressions are used to define and pass functions to the plot() function. The last example is:

`dc.plot(lambda z : ((z2-1)*(z-2- 1j)2)/(z2 +2+ 2j), title='((z2-1)*(z-2- 1j)2)/(z2 +2+ 2j)')

Which results in the following plot:

hsvcolor

This is like dcolor except that it does not convert the HSV image to RGB

python hsvcolorExample.py

Will create the images. The last image produces:

rgbcolor

This is designed to show the magnitude of abs(z). White means big, shades of green means intermediate, and black means small.

python rgbcolorExample.py

Will create the images. The last image produces:
