Teaching, courses and Final Projects

  • Degree courses
  • Interacció i Disseny d'Interfícies (IDI) at Facultat d'Informàtica de Barcelona
  • Master Courses
  • Fast Realistic Rendering (FRR)
  • Scientific Visualization (SV)
  • Final Projects (TFGs & TFMs)
  • I commonly supervise final projects that have to deal with Computer Graphics, Visualization, Interaction, and Mobile applications. More concretely, I have proposals for:
  • - Visualization of Learning-based Language Translation systems 
  • - 3D scene reconstruction using 360 cameras
  • - Development of a visualization tool for medical data inspection
  • - Visualization of molecular models in mobile devices
  • If you are interested in any of those, or you have an original idea, just drop me an e-mail and we can discuss it.
