Question Depth Bias and Perspective-correct depth with dynamic sampling rate for Parallax Occlusion Mapping

I need an implementation of this technology in the form of a code, but I did not find anything on the Internet.

 

The HDRP implements this by default. That’s what the height map input for the default Lit shaders do, and what the Parallax Offset Mapping node for Shader Graph does. You can look at the code for those here:
