osgXR: Virtual Reality with OpenXR and OpenSceneGraph

This library is to allow Virtual Reality support to be added to OpenSceneGraph applications, using the OpenXR standard.

Status:

• Still in development, contributions welcome. Plenty of work to do.
• APIs to support OpenXR VR display output in OpenSceneGraph apps.
• APIs to support OpenXR's action based input and haptic output for controller interaction.
• OpenGL graphics bindings for Linux (X11/Xlib) and Windows (note that WMR only supports DirectX bindings).

Installation

Something like this:

mkdir build
cd build
cmake ..
make
make install

Getting Started

To import osgXR into a CMake based project, you can use the included CMake module, adding something like this to your CMakeLists.txt:

find_package(osgXR 0.5.0 REQUIRED)

target_link_libraries(target
        ..
        osgXR::osgXR
)

osgXR can also optionally be built as a subproject. Consider using git subtree to import osgXR, then use something like this:

add_subdirectory(osgXR)

target_link_libraries(target
        ..
        osgXR
)

If you have installed osgXR outside of the system prefix (CMake's default prefix on UNIX systems is /usr/local), you may need to tell CMake where to find it when you configure the project. You can do this by defining osgXR_DIR when invoking cmake, e.g. with the argument -DosgXR_DIR=$PREFIX/lib/cmake/osgXR where $PREFIX is osgXR's install prefix (CMAKE_INSTALL_PREFIX).
