A sample OBJ viewer for OSPRay using OpenVR SDK to work with the HTC Vive.
The Vive module defines additional VR specific types for OSPRay such as the VR Camera and (in the future) other types for foveated or distorted rendering and so on.
The ospray-vive app uses the module and the OpenVR SDK
to render to the HMD. This app is a simple OBJ viewer which uses
tinyobjloader to load.
