    Jolt Physics

    Jolt Physics

    A multi core friendly rigid body physics and collision detection lib

    A multi core friendly rigid body physics and collision detection library suitable for games and VR applications, used by Horizon Forbidden West. So why create yet another physics engine? First of all, this has been a personal learning project and secondly I wanted to address some issues that I had with existing physics engines. In games we usually need to do many more things than to simulate the physics world and we need to do this across multiple threads. We therefore place a lot of emphasis on concurrently accessing the physics simulation data outside of the main physics simulation update. ...

    The Open Toolkit library is a fast, low-level C# wrapper for OpenGL

    ...It runs on all major platforms and powers hundreds of apps, games, and scientific research programs. OpenTK provides several utility libraries, including a math/linear algebra package, a windowing system, and input handling. OpenTK is not a game engine, nor does it try to be one: It offers a useful set of tools and lets you decide how to use them. It is the ideal starting point if you want to write a game or scientific application from the ground up. The OpenGL specification specifies exactly what the result/output of each function should be and how it should perform. It is then up to the developers implementing this specification to come up with a solution of how this function should operate. ...

    A rhythm game made with HaxeFlixel

    ...The project includes the full game source built using Haxe and OpenFL, allowing contributors and modders to explore and extend the game mechanics, audio library, and visual assets.
