Is it possible to fake a world curvature so that using a fog isn’t as necessary, as far items sink below the horizon?

That is tricky with raytracing, since rays would need to be curved, and at least in this raytracer, ray steps are not all equal in size so doing that correctly could be very expensive.

But is generally a cool idea.

Fog is good too, though. It helps with a sense of scale, and it helps colors and distance noise not be too busy.
