Recent manufacturing tech now allows optical quality lenticular lens arrays (embedded within screen protectors), combined with high performance XR face trackers to comfortably view 3D images on mobile devices - directly - without glasses.
Currently, this 3Dsp tech is being used to view and edit depth-encoded images and videos. No games have yet been developed for 3Dsp. None. But I am working with a manufacturer who is providing a Unity SDK. This sounds like an interesting engineering challenge to me - to you too?
If you might be interested in branching and porting your HARDCODE VR to this new 3Dsp tech (it's just a new rendering pipeline) then i can send you the PDF file named "Autostereoscopic to 3Dsp Unity SDK Instructions"
Looking forward to hearing back from you,
