Of course it does, or does [1] look like normal perspective projection
to you? You have to keep the lens distortion in mind. Moreover have you
had a look at the projection code of stellarium? It definitely doesn't
use standard OpenGL projection, how could it?
I didn't have enough time during the short period I had access to the
Rift to look into both mathematical backgrounds - Rift and stellarium
projection.
