The JPEG of 3D: Bringing 3D scenes and objects into your 2D Android app with glTF
summary
Facebook adds first-class 3D posts to feed, accepting artists’ Oculus Medium and Facebook Spaces exports as a single transferable file and rendering them on Android using a custom OpenGL ES renderer. The pipeline uses binary glTF (.glb) with glTF 2.0 PBR materials, uploads tightly packed buffers straight to GPU, and supports Draco compression (≈10:1) to cut network cost. Sample renderer and parsing code target data URIs and one-file workflow; source is pending legal release and the implementation proves the feature works with live feed playback.
