Experiment with random bouncing dots in c++ and python, using Qt

Colliding Dots

A experiment with colliding dots with mass, size, speed, angular momentum. Implemented both in python and c++.

The python program:

python3 rotating_dots.py

The c++ program is build using make and cmake:

make
./build/dots

Use keys to control what happpens:

• use 1-4 to add/remove dots in various styles.
• 1 adds dots in a different color each time.
• use r/g/b to select dots by color
• use m/d to select which parameter to change
• use +/- to change that parameter for the selected colored dots.

The c++ version also displays a histogram of speed and directions.

Dependencies

• the python version needs PyQt5
• the c++ version needs Qt5
