The continuous advances in high-resolution image and volume acquisition, as well as computational advances in simulation, have led to an explosion of the amount of static and dynamic volumetric data that must be visualized and analyzed. This trend of acquiring and computing more and more data at a rapidly increasing pace ("Big Data") will continue in the future. As interactive visual exploration plays a crucial role to support volumetric understanding in science, physics, and engineering, it is of primary importance to develop scalable visualization algorithms, data structures, and architectures to deal with the ever-increasing resolution and size of volume data. This talk briefly introduces the challenges of massive volumetric visualization, and describes the methods and systems we have developed to increase the level of interactivity, scalability, and usability for exploration of extremely massive static and dynamic rectilinar volumetric scalar volumes on commodity platforms. This work was supported in part by the European Union (DIVA ITN) and by Sardinian Regional Authorities (CRS4/Big Data).
Enrico Gobbetti is the Director of Visual Computing at the Center for Advanced Studies, Research, and Development in Sardinia (CRS4), Italy. His research spans many areas of visual and geometric computing, with a primary focus on technologies for acquisition, storage, processing, distribution, and interactive exploration of massive and complex objects. Many of the technologies developed by his group have been used in as diverse real-world applications as internet geoviewing, scientific data analysis, surgical training, and cultural heritage study and valorization. Enrico holds an Engineering degree (1989) and a Ph.D. degree (1993) in Computer Science from the Swiss Federal Institute of Technology in Lausanne (EPFL), as well as Full Professor Habilitations in Computer Science and Information Processing from the Italian Ministry of University and Research. He regularly serves the scientific community as IPC member, editorial board member (Eurographics Forum, 2018-2011; The Visual Computer, 2010-now; Frontiers in Virtual Environments, 2014-now; IEEE Transactions on Visualization and Computer Graphics, 2015, now), technical committee member (IEEE Multimedia Communication, 2010-now; Human Perception and Multimedia Computing, 2012-now), and conference co-chair (EuroGraphics 2012, ACM Web3d 2013, EuroVis 2015, EGPGV 2016). He is fellow of Eurographics.
