How Unreal Engine 5 Nanite Virtualized Geometry Works
SIGGRAPH Advances in Real-Time Rendering · Talk · YouTube title: A Deep Dive into Nanite Virtualized Geometry
Why it's here
HN treats it as the definitive deep dive on Nanite, admired for the engineering ambition behind pixel-sized triangles and compute-driven rendering.
What it covers
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.
