I have been exploring the sample image capture app, as well as command-line tool, for object capture. I've not yet figured out the best practices for capturing the bottom of images. For example, I have been attempting to demonstrate this with a sneaker.
Per the WWDC21-10076 session, I have been circling around my object, taking photos using the sample capture app, using the automatic capture mode. While this is creating a 3D model, during my capture, I also turn my sneaker over, and capture the bottom. However, when my 3D model is created via the command-line tool, the "bottom" of the sneaker is always missing.
Is there a given configuration when creating the PhotoGrammetrySession.Configuration that would be ideal for also including photos of the bottom of objects? While I pause, rotate my object to show the bottom, and continue capturing, I find that the bottom of the object is nearly always missing, despite many image captures that do include the bottom.
