    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. ...

    Redot Engine

    Redot Engine

    Multi-platform 2D and 3D game engine

    Redot Engine is an open-source game engine that aims to provide a flexible foundation for building games — likely offering a modern, modular structure so developers can compose only the systems they need (rendering, physics, input, scripting, etc.). It is built to give a base framework rather than a full “batteries-included” engine, which makes it suitable for developers who prefer minimalism, want complete control over architecture, or desire to build custom workflows. Because it’s open-source, Redot-Engine is potentially community-driven, allowing anyone to inspect, extend, or customize core functionalities. ...

    Lumix Engine

    Lumix Engine

    3D C++ Game Engine - yet another open source game engine

    ...It features a modern, component-based design (entity-component-system) and offers a full editor — enabling developers to build games in a WYSIWYG style similar to engines like Unity, while staying in a lightweight, open environment. The engine supports advanced rendering (with PBR, HDR, deferred rendering), physics, audio, animation, scripting (via Lua or even JavaScript via plugin), and more, giving it a robust feature set for realistic 3D games or simulations. Users appreciate that much of the engine — rendering, assets, scripting, editor — can be hot-reloaded, which greatly speeds up iteration. It runs on Windows and Linux, is MIT-licensed, and is backed by a community that provides documentation, demos, and examples (such as a demo platformer).
