Photogrammetry empowers you to create realistic high-fidelity assets at speed from everyday objects. By placing a variety of small objects on a rotating surface, you can capture them from every angle. We recently published an expert guide about that 360° capture process that helps you master the art of photogrammetry.

All you need to have to capture your objects is a decent camera, a powerful light, and a small rotating surface, such as a simple wooden round table for cheese. You don’t need any expensive gear, but having a dedicated room is a bonus.

You can use any camera or light, but a good lens and a powerful light give you better results and the Scene is simpler to set.

This guide explains how to use a rotating surface to do a 360° capture with the camera and the light at the same position. The whole process is pretty fast, and the results will convince you to use photogrammetry whenever you can.

Imagine using any composition of objects and creating larger versions of them in your Scenes. Take inspiration from the world around you, and use your creativity to bring your project to life!

Reconstructing the model

The reconstruction process basically follows the same process that is described in our photogrammetry ebook. This guide on creating assets from objects on a rotating surface shows you some tricks to easily process UV generation with Zbrush.

Importing and using the model in Unity

Using the High Definition Render Pipeline (HDRP), you can use tileable materials and a layered shader to make better quality games and applications. In just a few hours, you can produce assets that look as good as this:

Mastering the photogrammetry process can save you a lot of time. I hope our new guide will help you get to grips with the photogrammetry process. Free your creativity and don’t hesitate to post your own creation on the forum – enjoy it! Check out the Fontainebleau Demo on GitHub to see what we made with photogrammetry.

    Not sure about “The whole process is pretty fast” when it’s about taking, importing and aligning 500 photos for just one set of rocks.

  3. Any good free photogrammetry software out there?

    1. I’ve tried https://alicevision.github.io/ It’s probably the best available without a price tag.

    2. My personal favourite is 3DF zephyr – https://www.3dflow.net/3df-zephyr-free/ – which is free and very affordable in case you wish to upgrade. The 3D models are very good and it’s very easy to learn.

      Another great option is meshroom https://alicevision.github.io/ – It has a nice node-based interface, but the results are often worse.

      Another all-time-favourite is agisoft – https://www.agisoft.com/ – but it’s not free.

  4. Now use it on something other than a rock.

    1. This is actually a very popular technique to scan props and costume elements

      1. I’m aware of that but we have seen absolutely nothing about photogrammetry from Unity Technologies that explores the details needed for things with more topographically complex props. It is near universally cylindrical objects or things like rocks.
