Questions tagged [openvr]

OpenVR is an API and runtime that allows access to VR hardware from multiple vendors without requiring that applications have specific knowledge of the hardware they are targeting.

The OpenVR API provides a game with a way to interact with Virtual Reality displays without relying on a specific hardware vendor's SDK. It can be updated independently of the game to add support for new hardware or software updates.

OpenVR was once called the "Steamworks VR API". SteamVR is the related server that runs on the client and implements the OpenVR API for desktop applications to use.

Official SDK is available on Valve Software's GitHub.

Documentation for the API is available in the wiki.

More information on OpenVR and SteamVR can be found on http://steamvr.com
