3D & Augmented Reality

Part of SCRAPs committment to public engagement involves exprimenting with technologically-enabled learning.

Three-Dimensional (3D) Modelling

At the moment we are focused on generating 3D models of our excavations, as well as some artifacts, which we use during public presentations, whenever possible. We host our 3D models for public viewing on our affiliated Sketchfab site, AU-Virtual Archaeology Lab, where you can see the SCRAP collection of models, as well as other interesting archaeological materials.

In constructing our models, we currently make use of a combination of techniques. For small artifacts, we typically use a NextEngine 3D laser scanner and associated software, which is portable enough for us to take into the field if desired. For larger items–including artifacts and excavation areas–we have been experimenting with photogrammetry, using Pentax K-x and K-50 SLR Digital cameras (variety of lenses) and even still frames from video shot with an iPhone. Whenever possible, we experiment with open-source software, such as CloudCompare and VisualSFM, but also play around with our licensed copies of Agisoft and SimLab.

Augmented Reality

We are also currently developing an Augmented Reality tour app of the Alabama archaeological site, in consultation with local school teachers in the Stann Creek District, for the purpose of heritage education. Stay tuned for more on this project. In relation to this work, which is funded by National Geographic, we have taken part in the Explorer Challenge and Exchange Questionnaire for school children.
