To state clearly what you probably know - for non-stereo images - 
POV-Ray has the spherical built in camera which others have used for 
streetview-ish like VR environments for 15+ years (POV-Ray 3.5?). Early 
stuff was aimed at QuickTime VR - if I remember.

See the spherical.pov scene shipped with povray.
