3D scanning with the iPhone lidar

  • Know what to scan. People constantly disappointed with their iPhone lidar scans are often scanning things that have no chance of giving a good result. One of the most important things to know is that it doesn’t work well with smaller things and objects. Typically a shoe is too small. Also doesn’t work great with shiny/reflective things.
  • Avoid rescanning an area you have already covered, it will likely create alignment issues.
  • Scanning around something small/thin - like a statue or a chair or a wall -often doesn’t work well.
  • Make sure to properly cover every part of what you are scanning to avoid holes. I use a sort of spraying gesture, a bit like if I was painting with spray paint.
  • Go slowly and steadily.
  • A nice and clean crop makes a big difference in perceived quality. 3Dscannerapp, Polycam and Scaniverse offer in-app cropping.
  • Sketchfab offers lots of features helping turn a poor scan into an ok scan. I like to add an automated baked AO ground shadow (2nd editor tab), and then post process effects like sharpness, depth of field, saturation…
  • Set faces to single sided for rooms, so you can see the inside from the outside (last option in 3rd editor tab).
  • Adding 3D annotations in Sketchfab is a great way to turn a scan into a mini story.
