3D Digitization: Creating Virtual Copies of 3D Objects

Though academic institutions and museums are using costly 3D scanning equipment for their photogrammetry and 3D digitization efforts (see previous post), there are several free 3D scanning apps that allow users to capture photos taken 360 degrees around and object and easily generate virtual copies and 3D models on their own.

Autodesk 123d Catch
Autodesk 123d Catch is a free app for smartphones and tablets that allows you to create 3D scans of virtually any object. With built in guidance, it helps you set up proper lighting and provides advice for how to ensure 360 degree capture of the object. Once the object has been captured, you can upload to the Autodesk 123d cloud to share or download the free mesh-editing software to your computer for further editing and refinement of your 3D virtual model. The resulting file can be embedded into a website for virtual exploration or can be sent directly to a 3D printer.

Classroom integration example of Autodesk 123d Catch. Create a 3D scan capture of a 3D object found during an outdoor inquiry. *Bonus extension: upload the 3D model with an observation to iNaturalist and become a citizen scientist who shares with the global community.

Autodesk Recap
Similarly, Autodesk Recap allows you to capture 3D scans of an object, but has the added ability to leverage video as well. This “point cloud software” allows users to easily plan, measure, and visualize with advanced measurement as they can capture 3D objects and geographic sites, such as architectural layouts. Simply download the free software to a PC or Mac computer and upload digital photos or digital video files.

Classroom integration example of Autodesk Recap. Attach a digital camera (SLR, Smartphone, or GoPro) to a remote controlled helicopter drone to create a scan capture of your school campus and convert the capture into augmented reality.
