I am totally fascinated by SDFs. I can't help but wonder if we're not done with meshes, and everything will just be clouds of SDFs in the near future. Media Molecule's new engine has already gone there, and it looks incredible. It's a fascinating convergence of particles and polygons. And the approach jibes well with fast raytracing/raymarching... It just seems like a much richer primitive to start with than a triangle.<p>That said, I've only just started reading about it, so I am quite likely full of shit.
