Why use CubicNavigator instead of just opening a VR in QuickTime Player?
For using hardware accelerated OpenGL to give smoother VR panning at a high frame rate, for slideshows, cataloging, bookmarking scenic web sites, right-mouse button zooming, fluid fullscreen use, first-person-shooter mode, and so on. Also, CubicNavigator can display VR formats that QuickTime Player can’t, such as just-stitched raw equirectangular TIFFs for rapid previews, PTViewer Java content, etc.
