QVR: a library for Virtual Reality applications
QVR is a library that makes writing Virtual Reality (VR) applications very easy. It is based on Qt and requires no other libraries.
QVR manages all graphics views required for a VR application, based on a configuration for the target VR environment, from multi-node multi-GPU render clusters to head-mounted displays such as the Oculus Rift. A simple change of the configuration file makes the same application run on a completely different setup.
The application only needs to implement a single interface with just a few easily understandable functions. All rendering happens in a single OpenGL context so that there are no context switching and sharing issues. Furthermore the application does not need to care about threads, but is still free to implement any threading model.
QVR allows writing VR applications in pure OpenGL as well as using arbitrary external rendering engines. Examples are provided.
Supported platforms and hardware
The library should work on every platform that has Qt (i.e. all the platforms). Currently tested are Linux, Windows, and Android.
Supported VR hardware includes:
Custom large-scale VR labs with multiple GPUs and/or render clusters
HTC Vive and SteamVR with OpenVR
Oculus Rift with Oculus SDK
Google Cardboard and Daydream with Google VR NDK
HDK and lots of other head-mounted displays with OSVR
Almost all tracking and interaction hardware with VRPN
Desktop-based fake-VR for development and testing purposes, including experimental support for webcam-based head-tracking via webcam-head-tracker
Build and install the QVR library
libqvr first. After that, you can build
and try the example applications.
See the library documentation.
qvr-example-opengl-minimal: a minimal OpenGL-based example application that displays a rotating box.
qvr-example-opengl: a simple demo scene based on OpenGL.
qvr-example-openscenegraph: a full-featured OpenSceneGraph viewer.
qvr-example-vtk: a simple example of a VTK visualization pipeline within a QVR application.
qvr-sceneviewer: a viewer for 3D models and scenes in many file formats.
qvr-videoplayer: a video screen in the virtual world, for 2D and 3D videos.
qvr-vncviewer: a VNC viewer. Put a remote desktop in your virtual world!
qvr-identify-displays: a small utility to check the configuration and left/right channel separation.
