DepthViewer can load any Portrait Mode photo with Depth Maps captured with an iPhone or iPad and show a 3D model of the image.
It will show you the Depth Map in a black and white image as well as a completely interactive 3D scene that you can zoom and rotate.
Depth Maps are embedded in photos taken with Portrait Mode on the Camera app of iOS devices. You can load HEIC/JPEG images with Depth Maps in the DepthViewer app from a file or from the Photo Library.
DepthViewer supports macOS, iOS and iPadOS.
