Distortion mesh gaps
Hello, I was wondering what kind of voodoo I need to apply to the distortion mesh coordinates to get it to fill the entire visible area. This is what I have so far: http://i61.tinypic.com/350a104.p...
Hey Lam,
Thank you for pointing me in the right direction, much appreciated.
There was a recent Valve paper talking about the dead-zone when rendering to VR headset: basically not all of your pre-distorted buffer is visible once distortion is applied and the final content is presented.
My trick with the depth buffer prevents anything in the invisible region from rendering and consuming GPU cycles.
It might be that I am over-culling atm (gaps and all) but with DK2 I am getting +5% performance back and somewhere in that region with CB.
