3D SBS to Interlace

[Imbalanced Zero 2]

If you have a Passive 3D TV or Monitor, this shader should be useful. It should allow you to watch Side-by-Side broadcasts without you needing to switch to 3D Mode. And the best thing is you get to keep your EPG intact. It will only work in full-screen, not entirely sure how you make it work when it's windowed, but maybe someone else will figure that one out.

float grid = frac(tex.y*halfscreenheight);


if (grid>0.5) {
return l;
} else {
return r;
}

Would this work with DLP projectors?

 

Think I need checkerboard mode instead of interlace for DLP
