Why not billions of triangles? Unreal is betting on Nanite because triangles have so many nice properties in addition to having the whole art pipeline already set up.
(I could not get the URL to load. Maybe HN hugged it)
Triangles have no volume and no diffraction occurs inside them as it does with Platonic solids. The idea is that real-time raytracing will allow complex variations and interactions of "Platonic dust particles" and the rays bouncing and refracting between and in them. It would be a more expressive "clay" for the AI to tinker with than triangles - the orientation/color/transparency changes of each solid will be able to elicit more visual effects than doing it with flat triangles.I got banned from Eleuther discord today The One#3740
