Draco compresses vertex positions, normals and UVs with minimal visible loss. A furniture model that would be tens of megabytes uncompressed can load in a fraction of the time on mobile.
Web viewers decode Draco on the fly using a small WebAssembly decoder. Thridify delivers models draco-compressed and optimised for fast loading on any device.
Why it matters
Load time is conversion: a heavy model that stalls on 4G loses the shopper before the first spin.
