Unlit Fake Curved World Shader
An article by 
Tried to get world position from depth texture, but it didn’t work.. then founded COMPUTE_DEPTH_01 instead,
makes nice curve effect when applied to meshes (pushing the y vertices down based on depth).. although breaks a bit depending on camera rotation/position..
Shader source:

without curve-shader:
But if you are looking for nicer curve effect, here’s one:

Rather than grabbing depth, since you’re in the vertex shader anyway, couldn’t you just apply MV and P transformations separately, and then do your transformation while in view space? Unless you’ve scaled the camera transform, you should be at world scale in local camera space at that point.
Yes, wasn’t really useful effect the way i left it..and would look nicer if do real curve, instead of just pushing on Y..
