I am not trying to implement it, I want to know if something that does something like that exists already.

It sounds like something a VFX compositor like Nuke would do, but I haven't tried it myself.

I have the following image and depth map from a CV paper:

[![enter image description here](https://i.sstatic.net/QsXCt.png)](https://i.sstatic.net/QsXCt.png)

I want to know if there is an existing way to apply screen space rendering to a pre-existing image.

Before someone yells ate me saying "Why render over a literal picture when you can only make it worse!"

I have a program that changes multiple aspects of the original image, (color of certain objects and re-texturing of some surfaces).

So the original colors are wrong with respect to the modified image.
