Course overview
The Summer School is designed to comply with the increasing demand for researchers with different and cross-disciplinary backgrounds who are able to manage virtual environments and to exploit the analytical potential of 3D data in a variety of scientific endeavours. The courses are suitable for undergraduate/graduate students, PhD students, post-doctoral researchers, and professionals in the field of anthropology, archaeology, medicine and dentistry who are interested in developing fundamental skills in 3D data acquisition and post processing. Participants will acquire specialised notions on the different kinds of technology employed in 3D data acquisition (e.g., surface scans, X-ray computed tomography – CT), and on a variety of methods for post processing surface data (such as segmenting/visualizing image data from (micro)-CT sources) to create and analyse 3D digital models.

Learning outcomes
Virtual environments are currently pivotal to a number of research fields including anthropology, archaeology, the study of cultural heritage, medicine, and dentistry. In particular, new technologies for acquiring and post-processing three-dimensional (3D) image data, originally developed for medicine and engineering, have been increasingly applied to anthropology and archaeology for data collection, preservation, and analysis. Three-dimensional digital models can be considered as faithful copies of original data that facilitate replicability of experiment and reproducibility of results, and can be used for a broad set of non-invasive analyses comprising pure metrics, morphological analysis, tissue analysis and novel approaches to virtual integration and restoration. All these applications have great potential and disclose unseen opportunities for the preservation and dissemination of our biocultural heritage.

Additional information

Class 1 (10th - 14th June)

3D MODELS FOR ANTHROPOLOGY, ARCHAEOZOOLOGY AND CULTURAL HERITAGE

The class will experiment and get familiar with the acquisition of 3D data by practicing different techniques and supplies (blue light scan, laser scan, photogrammetry). Participants will be given a detailed overview of the general concept behind CT scanning, while dedicated datasets will be provided by the organisers. Raw models will be post-processed using Geomagic Design X to create a final product that can be straightforwardly used for display, morphometric analysis, and more elaborate analyses . CT Data will then be processed using Avizo Lite, a multipurpose tool designed for effectively discriminating between internal tissue proportions and for the creation of 3D models starting form computer tomographic datasets.

 

Class 2 (17th - 19th June)

MORPHOSTATS-3D

Quantitative analysis is increasingly considered as a critical part of scientific research in the realm of anthropology, archaeology, and cultural heritage. New 3D technologies facilitate the quick and accurate generation of high volumes of data that need to be managed and analysed. This course will provide participants with basic concepts and techniques of geometric morphometrics. Viewbox software will be used to capture the geometrical characteristics (shape variables) of 3D surface models (e.g., osteological and archaeological materials). A 3D template of (semi)landmarks will be created in order to create a configuration of homologous points that correspond in all specimens of a data set. Subsequently, the template will be applied to the targets and the sample will be statistically analyzed by means of Generalized Procrustes analysis (GPA) and Principal Component analysis (PCA). Visualization of shape changes along the principal axes will be obtained by Thin Plate Spline (TPS) interpolation. Specific issues will be addressed during the course, such as coping with incomplete osteological/archaeological materials
