VIGNETTE (post-processing effect 3)

This was the most fun I’ve had debugging something in a while. This was really simple to implement, although I can’t really say a lot. The initialization was the same as the other effects, the actual logic of it was pretty similar, the shader wasn’t too hard to write too, but added up it was pretty bad. I accidentally left one of the push parameters in the CPU code as an int, but a float in the GPU code, which I ended up having to chase down for quite a while. The values are over the top on the image so it is more visible on the screenshot, of course I won’t leave it like this.

Also, I have written a new readme for the github page.

I just kinda wanted to, and thought why not?
