Put this project onto github for the purposes of archiving old projects. Made in 2019.
Added some optimization and color changes. Originally could only handle 5,000 circles but can now handle 84,000 at 70 FPS on my computer.
Made this project because I wanted to learn how to make a simple physics engine with circles colliding. The circles conserve momentum and displace the other circles. I also wanted to figure out how to optimize the code so that thousands of circles could collide without slowing down the computer too much and I did that through spatial partitioning.
