Welcome to the Computer Graphics Group website, a research stream part of CITI - a Portuguese research centre hosted by the Department of Informatics of Faculty of Science and Technology of the New University of Lisbon.

The activities are mainly focused on tools, algorithms and techniques for data visualization, geometric modeling and physically based simulation and animation. More specifically, our research interests have been the following:
  • particle systems as a simulation tool for cloth modeling and animation
  • algorithms for isosurface visualization, including noisy data
  • automatic generation of guided tours through geometric walkthrough models
  • techniques suitable for urban monitoring based on data obtained by remote detection
  • landscape visualization for real-time navigation

More recently we are broadening our research interests. That is the case of:

  • grid-based visualization in co-operation with fellow Parallel and Distributed Processing Systems group
  • reconstruction of 3D models from images
  • visualization of documents.
  • general purpose GPU programming
