How does the TrueDepth camera work?
The TrueDepth camera uses structured light. There is an infrared projector and camera that projects a known pattern and are able to measure the distance to 30k dots (interpolated to 205k dots) at 30fps.
What devices currently have the TrueDepth camera?

How accurate is it?
There’s no single metric that fully describes the accuracy of 3D reconstruction. That being said each depth vector is accurate to ~0.5mm from 0.1-1.0 meters of distance. As you move the camera closer to the object being scanned, our algorithms refine the surface and fill in sharper detail. (You can try this for yourself by starting a scan far away from your face and then coming closer—the details of your eyelids will be resolved.)
Can I scan things with the rear-facing camera?
Unfortunately not at this time, as the TrueDepth camera is only front-facing on iPhones.
How big of an object can I scan?
Our algorithms do not require you to pre-set the bounding box of what you are scanning. The only limitations to how large an object you can scan are the memory of the phone.
What is the range of the scanner?
You can utilize the full range of the TrueDepth camera, which works up to about three meters, though it’s much more accurate at distances under one meter.
What is not scannable?
Extremely glossy/reflective things and see-through things (like glass). The TrueDepth sensor may not work in bright sunlight.
