This project aims to provide a Free and Open Source API and drivers for immersive technology, such as head mounted displays with built in head tracking.
OpenHMD is released under the permissive Boost Software License (see LICENSE for more information), to make sure it can be linked and distributed with both free and non-free software. While it doesn't require contribution from the users, it is still very appreciated.

Using make:
./autogen.sh # (if you're building from the git repository)
./configure [--enable-openglexample]
make
sudo make install
Using CMake:
With CMake, you can enable and disable drivers to compile OpenHMD with. Current Available drivers are: OPENHMD_DRIVER_OCULUS_RIFT, OPENHMD_DRIVER_EXTERNAL and OPENHMD_DRIVER_ANDROID. These can be enabled or disabled adding -DDRIVER_OF_CHOICE=ON after the cmake command (or using cmake-gui).
cmake .
make
To avoid having to run your applications as root to access USB devices you have to add a udev rule (this will be included in .deb packages, etc).
as root, run:
echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="2833", MODE="0666", GROUP="plugdev"' > /etc/udev/rules.d/83-hmd.rules
echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"' >> /etc/udev/rules.d/83-hmd.rules
echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="28de", MODE="0666", GROUP="plugdev"' >> /etc/udev/rules.d/83-hmd.rules
udevadm control --reload-rules
After this you have to unplug your device and plug it back in. You should now be able to access the HMD as a normal user.
CMake has a lot of generators available for IDE's and build systems. The easiest way to find one that fits your system is by checking the supported generators for you CMake version online. Example using VC2013.
cmake . -G "Visual Studio 12 2013 Win64"
This will generate a project file for Visual Studio 2013 for 64 bit systems. Open the project file and compile as you usually would do.
Using Make:
export PREFIX=/usr/i686-w64-mingw32/ (or whatever your mingw path is)
PKG_CONFIG_LIBDIR=$PREFIX/lib/pkgconfig ./configure --build=`gcc -dumpmachine` --host=i686-w64-mingw32 --prefix=$PREFIX
make
the library will end up in the .lib directory, you can use microsoft's lib.exe to make a .lib file for it
Using CMake:
For MinGW cross compiling, toolchain files tend to be the best solution. Please check the CMake documentation on how to do this. A starting point might be the CMake wiki: http://www.vtk.org/Wiki/CmakeMingw
If you're linking statically with OpenHMD using windows/mingw you have to make sure the macro OHMD_STATIC is set before including openhmd.h. In GCC this can be done by adding the compiler flag -DOHMD_STATIC, and with msvc it can be done using /DOHMD_STATIC.
Note that this is only if you're linking statically! If you're using the DLL then you must not define OHMD_STATIC. (If you're not sure then you're probably linking dynamically and won't have to worry about this).
Will be available soon.
See the examples/ subdirectory for usage examples. The OpenGL example is not built by default, to build it use the --enable-openglexample option for the configure script. It requires SDL, glew and OpenGL.
An API reference can be generated using doxygen and is also available here: http://openhmd.net/doxygen/0.1.0/openhmd_8h.html
