Increasing AR Realism with Lighting
summary
ARCore adds Environmental HDR: a machine‑learned pipeline (trained on 50 million samples) that runs on phones (demoed live on Pixel 3) and outputs a main directional light, 27‑coefficient ambient spherical harmonics, and a 16‑bit HDR cubemap for reflections. The system recovers clipped sunlight and far greater dynamic range, produces matching directional shadows and moving specular highlights, and plugs into Scene Viewer and Unity; availability slated for ARCore later this summer.
