I'm currently doing anaglyph. How to move left and right along the x axis,
my shader moves along the axes xy as correct?
Code:
sampler BaseTextureSampler : register( s0 );
HALF4 main( HALF2 ZeroTexCoord : TEXCOORD0 ) : COLOR
{
float left_pos = 0.008;
float right_pos = -0.008;
float4 left =
HALF2 has the .x and .y properties. So just do something like HALF2
leftCoord = ZeroTexCoord; leftCoord.x += left_pos; Then sample the color at
the new coordinate. However you should note, that the color you will be
returning in that function will be for the original pixel location. Shaders

If you go outside of the 0.0 - 1.0 range it will be capped to 0.0 or 1.0.
I can't think of a way to fix that problem, since it would require rendering
a bigger view than the users resolution.

You could go cheap and just add a frame around the edges to hide the ugly
parts.

That's not even how anaglyph images work. If you look at that through
your colored glasses you won't see a depth effect.
You need to render the scene twice, once with a camera moved a little
to the left and rotated to the right, and once with one moved a little
to the right and rotated to the

They are using a 3d source in the example of your link. It looks like a side by
side texture containing the left and right eye images.
The line
tex.x = tex.x +0.5
after the first sample is taken switches to the second image on the same
texture to take the right eye's sample.
As Alexander said
As you can see in the following image, they're using two images:

While you are only using one. They combine the left with the right
picture (hence the + 0.5).
