Hello. I am trying to calculate the view direction in a blit pass for a image effect; but I am having some trouble calculating the direction each pixel is looking/pointing. The result I need is a normalized float3. I tried quite a few different attempts but I guess my matrix math is too weak. The closest I've gotten is float3 viewdir = mul(_CameraToWorldMatrix ,float3((.5-o.uv.x)*_AspectRatio,.5-o.uv.y,1)); Where I set _CameraToWorldMatrix and _AspectRatio in c#. All help is greatly appreciated!
