The JPEG of 3D: Bringing 3D scenes and objects into your 2D Android app with glTF
summary
Facebook adds interactive 3D posts to Android and web by shipping scenes in glTF (binary .glb) and rendering them with an OpenGLES pipeline and a minimal Java renderer (source on fbsamples). 3D Photos convert depth maps to foreground/background meshes, and Draco mesh compression achieves up to 10:1 size reductions so network is the bottleneck not decode. Plans include PBR materials (Filament), GPU-friendly texture compression with client-side transcode, and per-primitive draw calls for efficient rendering.
