Stencil Optimization in Unity
Can I get the mask of unneeded pixel for the DK2 distorsion? I want to make the stencil mesh optimization sugested by Valve in the "Advanced VR Rendering" conference. http://www.roadtovr.com/valve...
Doing it right requires knowledge of both the distortion algorithm and the user's head shape, since the objective is to stencil out the exact pixels that wont be visible for a particular user through the lens. The oculus automatic camera configuration might help by providing a camera frustum that is already pretty optimal, but chances are you will still get reduction in FOV for some users with a naive implementation.
