The two workflows
Everything up to the moment you tap + 3D Scan left or + 3D Scan right on the order screen is the same in both workflows, and everything after you tap Save in the preview is the same too. The difference sits in between.
| FaceID Camera | Structure Sensor | |
|---|---|---|
| Hardware | The TrueDepth camera in the device | A Structure Sensor on the iPad |
| Devices | iPhone X or newer, iPad Pro | iPad only |
| Checks before scanning | Your account must allow it, and the device must have a TrueDepth camera | None |
| Scan mode question | No, scanning starts immediately | Yes: Foot scan or Foot- and foambox scan |
| Screen orientation | Portrait, except on the newest iPads where the camera sits on the long side; those go to landscape | Landscape |
| Workflow-specific settings | Mirror Clip | Gravity mode, Structure Version |
| Battery indicator on the scan screen | No | Yes, of the sensor |
Both workflows are set up for foot scanning: a small scan volume, a fine level of detail, and tracking tuned to an object you walk around.
