A Matter of Scale - Scale Matters

Speaker:  Eduard Gröller – Vienna, Austria
Topic(s):  Graphics and Computer-Aided Design


Scale and scalability have been recurring topics in visualization and visual computing. Multi-scale techniques have been efficient strategies to cope with complexity in various areas of our field. In the simulation community multi-grid and scale-space approaches have for a long time been an appropriate tool to accommodate accuracy requirements and performance constraints. Hierarchical methods and hierarchical data structures are used extensively in all areas of (computer) science. Recent developments like big and smart data, machine learning with vast training data, and advances in various vibrant application domains pose novel challenges to scalability and use of scale way beyond typical multi-scale techniques. In the biological domain phenomena are now modeled across very many scales, from individual atoms to proteins, to entire cells and beyond. Smart cities require the representation of many diverse networks, entire communities, neighborhoods, individual buildings, down to specific rooms, aso. Scalability has always been an important issue in information visualization and visual analytics as well. Recently, increased data sizes and complexity led to innovative strategies in incremental analytics and prediction, for example. Cartography has been an area where several scales have traditionally been handled concurrently. In the past islands of data were living in relative isolation, this information is increasingly growing together to fuel the digital transformation of society. In this talk we want to take a new look at scales, multi-scales, and scalability. Interesting topics in this respect are: scale-transparent visual computing, cross-scale visualization and interaction, massive multi-scale techniques, scale integration, cross-scale labeling and annotation, cross scales on time and space, cross scales on structure and dynamics (e.g., physiology), and continuous scales.
