(Part IV) This session collects contributions concerned with 3D data and how they are employed to tackle research questions or for proficient presentation. While much attention has been paid in recent years to evaluate different methodologies of data acquisition, compare algorithms for data processing or querying of 3D data, much less attention has been given to provide information on data quality required to solve research questions. What resolution is required or useful to display data in a 3D viewer? What precision is needed for comparative study of gypsum casks? What do we learn from comparative studies with regards to required data quality? How can we analyse 3D data to answer specific archaeological questions? How to acquire color and 3D information from the same object? This session particularly invites presenters working with 3D data that can provide feedback towards the process of acquisition to optimize data collection and to identify best data collection procedure for a given project. At the same time we welcome contributions that are focused on performing analysis of 3D data to solve archaeological questions and are predominantly application based or based on acquisition methodology.
