Broken mirror effect (camera displacement)
This is fantastic. A different camera displacement per-pixel. Based on a pixel RGB value. I’ve often wondered how to easily do curved rays in space. These are straight-line rays but you are moving the camera per-pixel (ray). Yes this is SDF raymarching, not a classic polygon rendering.
So you can make you camera look around corners to some extent, like the top of your rendered image can be looking from above, and the bottom looking from below.
