A Deep Dive into Nanite Virtualized Geometry
SIGGRAPH Advances in Real-Time Rendering

Brian Karis's SIGGRAPH 2021 talk explains how Unreal Engine 5's Nanite virtualized geometry works. It covers mesh import, the data structures, streaming, decompression, culling, software and hardware rasterization, and shading.
HN treats it as the definitive deep dive on Nanite, admired for the engineering ambition behind pixel-sized triangles and compute-driven rendering.
