During my Work at Cosalux I have developed a Virtual Reality Game for BASF. My part on this project was main gameplay programming, VR implementation and interaction as well as parts of the visuals like VFX, shader effects etc.
The VR game was developed using Unreal Engine 4 and Oculus Rift. To provide further immersion the user was able to control his/her speed and direction using a VRGO chair, which has a builtin accelerometer.
