• Upper Pitch, maximum vertical inclination in degrees for limiting the view up
  
• Left Yaw, maximum horizontal inclination in degrees for limiting the view left
  
• Right Yaw, maximum horizontal inclination in degrees for limiting the view right
  
• HAOV, sets the panorama’s horizontal angle of view
  
• VAOV, sets the panorama’s vertical angle of view
  
• HFOV, sets the panorama’s horizontal field of view
  
• Background Color, color shown for partial panoramas visible areas
