OpenVR SDK
API and runtime that allows access to VR hardware
... hardware or software updates. This means that you can access the position of the headset using only one API call and it works for all headset brands (Oculus, Mixed Reality, Vive, etc)! The API is implemented as a set of C++ interface classes full of pure virtual functions. When an application initializes the system it will return the interface that matches the header in the SDK used by that application.
