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 up a model using Blender
- Optimizing the topology of a model using Instant Meshes
- UV unwrapping and baking textures from an original high-poly model to an optimized low-poly model
