pseudo light
I am getting this weird interference pattern from my shader on just a couple of sides of the cube. The shader is ray marching a volume and generally works, but this happens with a particular alignment of the directional light. I'm wondering if somebody has experience with what causes this type of pattern? (Ignore the banding, it's the circular patterns that I'm wondering about.)

I'm pretty sure this comes from floating point approximation.
IDK what math you're doing here, but it looks like a comparison check ( if x<y or something) and from one pixel to the other one of the compared values varies a little due to preceding floating point calculations.
