Is it possible to make a post process effect simulating a star filter (as known from real-world cameras) that only requires one single shader pass?
So far I've only found sources using 5 up to 24 passes, but since those topics alltogether are rather outdated I thought there might be some possibility to do this in one pass with Shader Model 5.
I'm talking only HLSL, so please no DirectX API function calls (D3D...) here.
Thank you in advance!
