Chunk streaming and LOD decisions behind dense Web 3D streets — lessons from building HoiAnWorld.
A tourism-style street is not one model. It is a density problem: roofs, facades, props, and collision all compete for the same frame budget.
The workable approach was to stop thinking in “one beautiful scene” and start thinking in regions. Nearby chunks load first. Distant chunks stay cheap. LOD decides what “cheap” means.
The product lesson: visitors forgive simplified distant geometry. They do not forgive a frozen first interaction.
