Open Source Virtual Reality Software

CoffeeMud is a text-based virtual reality game engine (a MUD). It is a mature, full-featured Java codebase. It includes web (HTTP) and email (SMTP) servers, chat (IMC2 and I3) and web clients, and supports ANSI, MXP, and MSP.

UEVR is a powerful VR mod for Unreal Engine games, supporting versions 4.8 to 5.4. It offers full 6DOF and stereoscopic 3D support out of the box, along with three rendering modes: Native Stereo, Synchronized Sequential, and AFR. It works with OpenVR and OpenXR runtimes, enabling a smooth VR experience with optional roomscale movement and motion controls. UEVR also features a user-friendly GUI, in-game menu, and per-game configurations, allowing modders to enhance VR functionality with C++ and Blueprint support.

MyWorld is an open virtual reality and game engine. It is written and usable in C/C++. It has own abstract layers for Graphics and Physics. Actually we use Irrlicht for 3D-Rendering and GUI, and ODE for Physics. It is smart, powerful and easy to extend.

OpenReality will be a 3D Engine Library for development of Games, Virtual Reality and 3D Visualization applications. It will be very intuitive, and strongly object oriented. Of course, performance will have a great weight on the project´s decisions.

The VROnline project is universal 3D virtual reality engine for games with client/server architecture, free 3D camera, user configurable actions and AI scripts. It's based on C# and directX (now 9.0) technology. It can manage many data models(rpg,sims).
