About

EM3D

This utility app acts as a second screen for a 3D scanning application. It allows users to easily scan objects other than themselves by mirroring the scanning device's screen to another iOS device. This feature is particularly useful for capturing detailed 3D models.

Highlights
  • Second screen functionality
  • Mirrors scanning device screen
  • Facilitates scanning objects other than self
  • Standalone app option
  • Compatible with older iOS versions

Use Mirror Saver as a second screen when 3D scanning with EM3D: Ethan Makes 3D Scanner. Since EM3D uses the high resolution front-facing True Depth sensor, it can be difficult to scan anything other than yourself because you have to point the screen of the scanning device toward the object being scanned. The Mirror Saver feature in EM3D allows you to broadcast the screen to another iOS device, so you can hold the devices back to back and see what you're scanning . However, EM3D requires iOS 13 or higher. Devices that don't have iOS 13 or higher can download the standalone Mirror Saver app, which provides the screen functionality of the Mirror Saver feature.
