A new approach for rendering barrel distortion

Hello,
I've been looking into non-linear rasterization that could benefit VR and wrote paper about it.
Basically with this technique image can cover full headset screen, without borders, render with native anti-aliasing and in native resolution directly with lens distortions.

Paper is available online at

Hope VR community will find it interesting.
