These renders are for the left and right eyes of our dancing girl animation for the DK2 and Gear VR (Front face of cube map)
This simulates what the oculus gear vr does and what htc vive does and what the Sony Morpheus does to the image when it just looks at the dancing girl 90 degrees at a time.
Those HMDs are smart HMDs that convert equirectangular or cube mapped spherical images into the familiar 90 degree barrel shape.
While the Google Cardboard and othere HMDs are dumb HMDs (dumb HMDs don’t convert anything) and just have lenses to pincushion the barrel shape so the viewer sees a straight image.
