Do you mean as in ray marching, sphere tracing using the SDF of the 
shape? Or classic ray tracing?

I made a little ray-tracer that does the classic way as well as the 
sphere marching on cpu using the same scene file but different back end. 
There are noticeable differences in quality. (diff and compare done with 
imagemagick)

I've yet to use the GPU/vulkan as a back end for both. The goal is to 
have different back-ends as a "plug in".

Like your rewrite project.
