Open Source C VR Development Software

StereoKit is an easy-to-use open source mixed reality library for building HoloLens and VR applications with C# and OpenXR! Inspired by libraries like XNA and Processing, StereoKit is meant to be fun to use and easy to develop with, yet still quite capable of creating professional and business-ready software. HoloLens 2, Oculus Quest, Windows Mixed Reality, Oculus Desktop, SteamVR, Monado (Linux), and eventually everywhere OpenXR is! Flat screen MR simulator with input emulation for easy development. Builds your application to device in seconds, not minutes. Mixed Reality inputs like hands and eyes are trivial to access. Texture formats .jpg, .png, .tga, .bmp, .psd, .gif, .hdr, .pic, .qoi, equirectangular cubemap, procedural. Documentation generated directly from the source code, including screenshots.

An open-source framework for rapidly building immersive 3D experiences. You can use LÖVR to easily create VR experiences without much setup or programming experience. The framework is tiny, fast, open-source, and supports lots of different platforms and devices. Runs on Windows, Mac, Linux, Android, WebXR. Supports Vive/Index, Oculus Rift/Quest, Pico, Windows MR, and has a VR simulator. Simple VR scenes can be created in just a few lines of Lua. Writen in C99 and scripted with LuaJIT, includes optimized single-pass stereo rendering. Out of the box you get fast stereo rendering, VR controllers, hand tracking, haptics, spatial audio, 3D physics, PBR materials, SDF fonts, multiplayer, and more. The entire engine is 1MB and runs on LuaJIT, the fastest JIT compiler round these parts. Projects are just folders with scripts and assets in them, organized however you want.

Arcan is a powerful development framework for creating virtually anything from user interfaces for specialized embedded applications all the way to full-blown standalone desktop environments. At its heart lies a robust and portable multimedia engine, with a well-tested and well-documented Lua scripting interface. The development emphasizes security, debuggability and performance, guided by a principle of least surprise in terms of API design. For the main engine there has been quite some refactoring to reduce input latency; better accommodate variable-refresh rate display; prepare for asymmetric uncooperative multi-GPU and GPU handover; explicit synchronization and runtime transitions back and forth between low (16-bit) to standard (32-bit) to high-definition rendering (10-bit + fp16/fp32).

AVRS performs spatial 3D-sound processing allowing the arbitrary placement of sound source in auditory space. The main goal is to develop a genuine experimental flexible platform, that runs in a general-purpose architecture computer (standard hardware and software).

Forgotten Dream - audio version (russian language) Simple cross platform audio game. It's an experiment, attempt to find alternative approach to create virtual reality. libxml + libSDL + C

The VR_MUSICIEN project is based on the Chromium plateform and allows user to easily port their OpenGL code in a Virtual Reality Environment. This library especially computes the asymetric frustum for multiuser headtracking stereovision.

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.
