Applied Mesh Analysis: Automating Distant-City LODs in 'Marvel's Spider-Man 2'


The New York City of Marvel's Spider-Man 2 is roughly twice as large as that of earlier titles in the series. At the same time, new quality and performance constraints required the creation of additional distant city LODs. The manual distant-LOD geometry pipeline of Marvel's Spider-Man and Marvel's Spider-Man: Miles Morales was no longer viable. This lecture describes how Insomniac Games transitioned to automated distant-LOD geometry generation. In particular, it covers in-depth the applications of fundamental mesh analysis concepts (dual meshes, the Euler Characteristic, curvature estimation, etc...) to several difficult problems (beyond standard reduction and remeshing) that arise from the unique constraints regarding distant city LODs present in Marvel's Spider-Man 2.
