Introduction to 3D Photogrammetry

Photogrammetry is a technique that turns photos of real-world objects into detailed 3D models, perfect for creating realistic assets in video games, VR, and digital art. It lets you scan, texture, and render objects and environments for interactive apps or professional visualizations.

You don’t need prior photogrammetry experience, but basic knowledge of photography and 3D modeling is recommended to get the most out of this intermediate-level course.

You’ll learn how to capture, process, and optimize 3D models using photogrammetry, create realistic textures, set up lighting for renders, compare scanning techniques, and publish your models on specialized digital platforms.

You’ll need a digital camera (preferably DSLR or mirrorless), a tripod, a remote shutter release, optional polarizing filters, and a powerful computer. Recommended software includes Agisoft Metashape, Meshroom, and editing tools like Photoshop or Camera Raw.

The course teaches you how to capture complex objects and surfaces using coverage techniques, photo overlap, and lighting control to ensure accurate models and detailed textures—even on reflective or bulky surfaces.

You’ll learn to capture high-quality images, process them into realistic textures, and apply those textures to 3D models using editing and optimization techniques for integration into game engines like Unreal Engine.

Photogrammetry builds 3D models from photographs, while other methods like laser scanning use specialized sensors. Photogrammetry is more accessible and flexible; laser scanning is more precise but also more expensive.
