My wife and I watched the Lighter & Princess (点燃我，温暖你) Chinese Drama in December of 2022. The show featured an ultra smart programmer, and he coded an animated heart (Episode 5 @ 31:43). My wife challenged me to replicate the animated heart. This is my attempt. I thought it would be fun to do it in Qt and Python.
This is my first Qt program, and I kind of hacked this together until it looked kind of similar.
I have to give credit to the following:
- A javascript implementation - I only took the colours from it. Implemented my own logic and algorithm.
- Used the third formula offered in this article by Saanvi Gutta
- Learned a lot about Qt Animation and PyQt5 from this article by Salem Al Bream
- Learned how to draw on QPixmap and QPainter from this article by Martin Fitzpatrick
Thanks to the above references, I was able to hack this together.
I tested on:
- macOS Ventura
- Ubuntu 22.04 LTS (Desktop)
- Windows 10
Use the following command line instructions on Ubuntu and macOS. I am assuming that git is already installed.
Use equivalents on Windows 10.
git clone https://github.com/kanglu/heart.git
cd heart
python3.10 -m venv env
source env/bin/activate
pip install -r requirements.txt
# If you are doing this on Linux or Ubuntu you may need to update your library dependencies
#
# sudo apt install '^libxcb.*-dev'
python ./heart.py
