Is is possible to emulate an Oculus Rift? I would like to test my application but do not currently have a head-mounted display.

Oculus offers the option to emulate the device:

1.
Start the OculusConfigUtil.exe application.

2.
Select menu: Tools -> Service -> Configure...

3.
Select DK2 from the Debug HMD Type



4.
Launch any of the examples contained in CHAI3D/modules/OCULUS
