A Thorough Look into Spatial Mapping with HoloLens
summary
Practical guide to HoloLens spatial mapping: device scans continuously up to 3 meters using depth and environment cameras and an HPU, producing Unity-accessible meshes via SurfaceObserver that developers request as meshes with colliders for physics and occlusion. Examples include collaborative multi-user alignment, asset placement via a spatial anchor, and industry proofs (banking dashboards, Ford design reviews, Schneider Electric maintenance). Notes on limits: ~40° field of view, noisy meshes with holes and mirror artifacts, 2 GB RAM, ~3-hour battery, dev kit ~€3,000; post-processing and a room-scanning step are essential for reliability.
