Sphere tracing is awesome. So many effects can be so easily and cheaply approximated, apart from soft shadows also subsurface scattering, bloom/glare etc. Downs

Sphere tracing is awesome. So many effects can be so easily and cheaply approximated, apart from soft shadows also subsurface scattering, bloom/glare etc. Downside, while great for geometry describable by distance fields, it's quite useless with polygonal assets...
