The non-profit organization Open 3D Foundation (O3DF) presented an open 3D game engine Open 3D Engine 25.10 (O3DE), suitable for developing modern AAA games and high-fidelity simulations that can run in real time and provide cinematic quality. The code is written in C++ and published under the Apache 2.0 license. Support is available for platforms like Linux, Windows, macOS, iOS, and Android.
The O3DE engine was open-sourced in July 2021 by Amazon and is based on code previously developed in the proprietary engine Amazon Lumberyard, built on CryEngine engine technologies licensed from Crytek in 2015. After opening the code base, the development of the engine is supervised by the non-profit organization Open 3D Foundation, created under the auspices of the Linux Foundation. Companies like Epic Games, Adobe, Huawei, Microsoft, Intel, and Niantic have joined the joint work on the project. Engine includes an integrated game development environment, a multi-threaded photorealistic rendering system Atom Renderer with support for Vulkan, Metal, and DirectX 12, an extensible 3D model editor, a character animation system (Emotion FX), a system for prefab development, a real-time physics simulation engine, and mathematical libraries using SIMD instructions.
