HoloLens Feature: Spatial Mapping

A modern living room with a green-patterned sofa and coffee table.

Once you've designed some holograms with HoloLens, you'll need to get them to interact with the environment. That's where Spatial Mapping comes in. There are five basic purposes for using HoloLens's Spatial Mapping with your app:

  • Navigation: This lets your holograms know how to get around in the mixed-reality environment.
  • Occlusion: Occlusion mapping gives the user the impression that a hologram is casting light or shadow on a real object, or vice versa.
  • Physics: You can program physics into your holograms, so that one might bounce off of a surface, for example.
  • Placement: This allows you to place a hologram onto a real object, like a coffee table or wall.
  • Visualization: Essentially a "preview" mode, Visualization breaks down the room you're in so you can make a plan for your holograms.

All of the Spatial Mapping data for the room you're in can be saved between sessions so you can easily hop right back into a session.

Apple's iOS 26 and iPadOS 26 updates are packed with new features, and you can try them before almost everyone else. First, check Gadget Hacks' list of supported iPhone and iPad models, then follow the step-by-step guide to install the iOS/iPadOS 26 beta — no paid developer account required.
