macOS: Create your first 3D model from real-world objects (Photogrammetry framework)
** The framework has changed since this video was published. --sampleOverlap is no longer a valid parameter, so it needs to be removed from the main call. Simply remove the line "-l", "normal",
from the project (you'll see it on my project in this video on line 234 in main.swift. Once you delete it, the project should build/run fine. **
In this Swift macOS tutorial I’ll show you how to EASILY create your own 3D models out of real-world objects using RealityKit and the Photogrammetry API released at WWDC21. This is an incredibly easy process, albeit time-consuming due to both having to take a bunch of pictures, and for Xcode to build out your .usdz file. The final result is a 3D model that can be used in ARKit, or potentially games as well. I tested building these models out with an M1 chip MacBook Pro and an Intel-based T2 chip MacBook Pro. This Xcode tutorial is for Xcode beginners, intermediate, and advanced users.

There are a few requirements when considering doing this:
1. You need to be on macOS Monterey 12.0 beta or later
2. You need to have Xcode 13 beta or later installed
3. You need to have a decent spec’d Mac (preferably an M1, as they complete the process ~4x as fast as an Intel-based Mac)
4. You need a camera or phone to take pictures of your model; I used an iPhone XR
5. You need a model that doesn’t have too many reflective surfaces
6. You need to put your model on a dark, neutral background that doesn’t have texture
7. Preferably use a lazy-suzan while taking photos, and some kind of arm to keep your camera steady
Two different MacBook Pros were tested for build speed of the .usdz file:
1. 2019 16” MBP, 2.6 GHz 6-Core Intel Core i7, 16 GB 2667 MHz DDR4, AMD Radeon Pro 5300M 4 GB
2. 2020 M1 13” MBP, 16 GB RAM
Intel speeds at detail levels:
.preview: 12m 18s
.reduced: 24m 22s
.medium: 40m 6s
.full: DID NOT WORK, ERROR & CRASH
M1 speeds at detail levels:
.preview: 4m 52s
.reduced: 11m 10s
.medium: 11m 17s
.full: DID NOT WORK, ERROR & CRASH
