Dear shader programmers,
I am new to shader programming
What does the (((IN.Pos.xy / IN.Pos.w) + 1) / 2 indicate.
The code snippet is
float2 texc = ((IN.Pos.xy / IN.Pos.w) + 1) / 2;
With regards

It looks like some kind of texture projection with bias transformation.
Used for things like depth map shadows.
This code calculates a texture coordinate on the screen.
I used this and a dudv map to create refractive materials.
