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 maxfober.space/research/Perspective_of_Visual_Sphere-JM_Fober.pdf *I cannot post the full link due to my permission on the forum.
