Hi Björn, let me use this thread to suggest a new feature. I would like the positional tracking of the osgoculusviewer to be optional, possibly by calling a member function oculusDevice->setPositionTracking(false);
If you remember my use case, there is a camera strapped to a person's head, which already tracks the head position. Superimposing an external tracking would cause some issues. In the 0.5.0.1 version of the osgoculus viewer I've already added a switch to disable the tracking, but it seems I will have to repeat it for the current 0.7.0.0 enabled version (the master branch) Also, somewhat off-topic: I may have found an alternative to the DK2 head set by using an iphone 6 and Google Cardboard like devices, such as the Zeiss VR One. Combine this with the duet display driver (duetdisplay.com) and you can use this iphone-based headset with sufficiently low latency at 60 FPS while using the PC for rendering the graphics. As I need no positional tracking from the phone fed back from the PC, this will work for me.
