Principia

38 731 9.9 C++

𝑛-Body and Extended Body Gravitation for Kerbal Space Program

Project mention: A rudimentary simulation of the three-body problem | news.ycombinator.com | 2024-04-02

Principia is extremely impressive, they document all their math here: https://github.com/mockingbirdnest/Principia/tree/master/doc...
One interesting detail is that the source code makes extensive use of non-ASCII identifiers, for mathematical symbols and for the names of mathematicians. One of the two primary contributors is also an active contributor to Unicode

SolarSystem

7 55 6.2 C++

A solar system simulator with Verlet, using OpenGL for displaying.

Project mention: 4 hours of my .obj parser so far 😭 | /r/opengl | 2023-06-12

I also ported it in an opengl project: https://github.com/aromanro/SolarSystem
