Inspired by Johnny Chung Lee’s Wii projects, but disappointed by the lack of portability of his code, I decided to develop a version of VR head tracking on Linux using OpenGL.
While Johnny’s code is written in C# using DirectX for the 3D graphics, I wrote my code in C++ using OpenGL for 3D rendering. Unlike DirectX which only runs on Microsoft Windows, OpenGL rendering libraries are available for almost every computing platform.
The code is currently a bit rough around the edges due to the partially complete rewrite to more modular class-based C++ code (I originally wrote it in C). I am currently working on improving the modularity of the code, so that you can simply replace the wiimote communication library (cwiid) with the one that is available for your platform. I will improve this over the next few versions.
Besides the cwiid wiimote library, my code should be easily portable to any operating system which has an OpenGL implementation and a wiimote library similar to cwiid.
Future contributions to this project may include a more usable interface for tweaking the geometry and setting up the rendering to work better with your specific hardware.
