This class will introduce 3D imaging, i.e. the process of creating three dimensional digital copies of existing objects; and will discuss the relationship of such models with the original pieces of cultural heritage. After presenting briefly the available technologies, we will focus on photogrammetry, and on how to create low cost 3D scans of objects processing a series of photographs. We will also introduce some of the technical background to 3D printing for cultural heritage, including the research value of designing and printing 3D objects, some pedagogical possibilities for handling 3D objects (especially when originals are not available).

Choose an object that meets the requirements explained in the tutorial (i.e. it is not transparent, glossy, repetitive etc...). Take a sufficient number of photos, according to the complexity of the object's shape (minimum 35, preferably more). Request a trial account for Agisoft Photoscan (http://www.agisoft.com), or use any other photogrammetry software of your choice to process the images. Produce a textured 3D model of your target.
