Nanite Tessellation Nanite Tessellation, aka Nanite Dynamic Tessellation, aka Nanite Dynamic Displacement was the next major feature I worked on after Nanite it...

I'm finally writing up how Nanite Tessellation works. The first few blogs posts are up. More will be coming.

Lambert model (left), the classic “qualitative” Oren–Nayar QON model (center), and our new EON model (right), all at maximal roughness and the same single-scattering albedo color. The top and bottom rows show front and side-lit cases respectively. The EON model compensates for the energy loss of the QON model, producing similar brightness to the Lambert model combined with the characteristic “flattening” and enhanced backscattering of the Oren–Nayar model.
