The short version

  • Only Three.js has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft HoloLens 2 narrow field of view of 52 degrees limits visibility of holograms and causes parts of 3D objects to disappear when viewing up close; Three.js forward rendering pipeline only, no deferred rendering support
  • They diverge on capability: Microsoft HoloLens 2 covers Spatial mapping, Three.js covers WebGL rendering.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft HoloLens 2

  • Narrow field of view of 52 degrees limits visibility of holograms and causes parts of 3D objects to disappear when viewing up close
  • Heavy weight makes extended wearing uncomfortable and impractical for sessions longer than a few hours
  • Short battery life of 2.5 to 5.5 hours limits extended deployments without charging
  • Display is sensitive to bright light and sunlight, with rainbow color artifacts and poor outdoor readability
  • High price of $3,500 limits accessibility to enterprises with substantial budgets

Three.js

  • Forward rendering pipeline only, no deferred rendering support
  • No built-in collision detection or spatial indexing, requiring external physics libraries
  • WebGL dependency means no support for non-WebGL environments
