Chapter 6: 3D Scanning and Photogrammetry: Creating Your Own 3D Scans

In this chapter, we will be looking at 3D scanning and photogrammetry! Photogrammetry is the process of taking many photos of an object from multiple angles and then using software, such as Meshroom, to convert those photos into a 3D model. We will then clean up the scanned model in Blender and optimize the topology using a free program called Instant Meshes.

Once we have an optimized model, we will bake the textures from the original high-poly scanned model onto the low-poly optimized model. Let's get started!

The main topics we'll cover in this chapter are as follows:

Taking photos for 3D scanning/photogrammetry
Using Meshroom to convert photos into a 3D model
Cleaning ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
