Title: Visualization and Computer Graphics research at UFRGS/Brazil
In this talk I will present an overview of several ongoing projects I have been working at UFRGS, as well as some recent publications in theareas of information visualization and visual analytics, high performance computing, real-time rendering and geometric algorithms. My main focus will bein projects in the area of information visualization and visual analytics on the following topics: visualization of heart rate time series from exercise activities,phenological monitoring of forest ecosystems, and visualization of soccer data. I will briefly review a system for shape matching using the notionof depth complexity, and an algorithm for rendering massive transparent models called Hybrid Transparency.
Bio: Prof. Dr. João Luiz Dihl Comba, (UFRGS / Informatics Institute) is an Associate Professor at the ”Instituto de Informática, UFRGS” since 2002, where he leads research activities, teaches undergraduate and graduate courses, and is advisor for Ph.D, M.Sc. and B.Sc. students. Dr. Comba has a Ph.D. in Computer Science from Stanford University, United States (2000) with Prof. Leonidas J. Guibas as advisor, a M.Sc. in Systems Engineering and Computation from COPPE-Universidade Federal do Rio de Janeiro (1991) and a B.Sc. in Computer Science from Universidade Federal do Rio Grande do Sul (1987).
