Augmented reality

Placing digital 3D content over a live view of the real world

Also called AR

What is augmented reality?

Augmented reality, or AR, places digital content, such as 3D models, labels or effects, over a live view of the real world. A phone, tablet or headset tracks the room and keeps the content anchored in place as you move. You still see your surroundings, with the digital layer added on top.

Think of it like this

It is like a sticker you place on the world through your phone, one that stays put on the table as you walk around it.

Where it fits in a 3D project

  1. Create
  2. Surface
  3. Rig
  4. Animate
  5. Render
  6. Export

Export: Saving and sharing the result: file formats, engines and printing.

How augmented reality works

  1. 01The device’s camera and sensors map the room, finding floors, walls and tables.
  2. 02It tracks its own position as you move.
  3. 03A 3D model is placed at a spot in that map.
  4. 04Each frame, the model is redrawn from your new viewpoint, so it appears fixed in place.

Augmented reality vs virtual reality

PropertyAugmented realityVirtual reality
What you seeThe real world plus digital objectsA fully digital world
DevicePhone, tablet or see-through headsetA headset that covers your view

Typical useProducts, directions and effectsGames, training and virtual tours

Use AR when the digital content relates to the room you are in; use VR when you want to take people somewhere else.

Where augmented reality is used

  • Previewing furniture and products at full size at home
  • Face filters and effects in social apps
  • Step-by-step repair and assembly guides

Beginner tip

Model in real-world units and keep the model light, with compressed textures. AR apps show objects at true size, and phones must draw them in real time while tracking the room.

Augmented reality FAQ

AR vs VR: what is the difference?
AR adds digital objects to your view of the real world, usually through a phone or see-through glasses. VR replaces your view entirely with a digital world inside a headset. Mixed reality sits between the two.
How do I make a 3D model for AR?
Model or generate the object, keep its polycount and textures light, set its scale in real-world units, and export it in a format your AR app supports. GLB is widely used, and some platforms have their own formats.
Do I need a headset for augmented reality?
No. Most AR today runs on phones and tablets through the camera. Headsets and smart glasses give a hands-free view, but you do not need one to try it.
