3D SBS to Interlace

Recommended Posts

Imbalanced Zero

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.

sampler s0 : register(s0);
float4 p0 : register(c0);

#define width (p0[0])
#define height (p0[1])
#define halfscreenheight height/2
float4 main(float2 tex : TEXCOORD0) : COLOR 

tex.x = tex.x*0.5;

float4 l =tex2D(s0, float2(tex.x,tex.y));

tex.x = tex.x + 0.5;

float4 r =tex2D(s0, float2(tex.x,tex.y));

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 :P
