An Oculus Quest VR headset is currently pre-ordered from Oculus. As soon as it arrives at the office I'll work on making a version of VR Tourviewer for Oculus Quest. Since the Quest functionality is similar to the Oculus Rift it could be pretty straight forward.
I'll post here again if I have any news on the subject.
Greetings, Ruud
Since June 2019 the Quest version of VR Tourviewer is available.
