Epic Games 架构师 Brian Karis 在 SIGGRAPH 2021 上的重磅解析，深度剖析虚幻引擎 5（Unreal Engine 5）Nanite 虚拟化几何体技术内幕。涵盖网格导入、数据结构、流式加载、实时解压、几何剔除、软硬件光栅化以及着色全流程。
为什么 HN 推它
HN 公认关于 Nanite 最权威、最透彻的技术深剖，把几何精度推到像素级别、以计算着色器驱动渲染的工程魄力令人叹服。
「这期 SIGGRAPH 演讲绝对能彻底颠覆你的认知。」HN 网友原话：This siggraph session will expand your mind
英文原摘要（HackerTube / Claude 整理）
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.

Here's an overview of a modern geometry pipeline
Unreal Engine's Nanite technology has the same problem.
the sheer amount of engineering horsepower they put into driving it into production just boggles the mind
everyone is, in fact, moving away from the idea of a "graphics API" altogether
