The Department of Computer Science at the University of Cyprus cordially invites you to the Colloquium entitled:

Crowds for Real-time Applications


Speaker: Dr. Nuria Pelechano
Affiliation: Polytechnic University of Catalonia (UPC), Spain
Category: Colloquium
Location: Room 148, Faculty of Pure and Applied Sciences (FST-01), 1 University Avenue, 2109 Nicosia, Cyprus (directions)
Date: Tuesday, September 15, 2015
Time: 11:00-12:00 EET
Host: Yiorgos Chrysanthou (

The simulation of large numbers of autonomous avatars can be a big challenge for real-time applications. In this talk I will cover some of the most relevant areas regarding this topic including local movement, planning, navigation meshes, synthesis of animations and rendering. Local movement can be achieved through a combination of physical forces and rules given by psychological and geometrical factors. At the higher level, local movement needs to be driven by a navigation technique, such as multi-domain planning based on different representations for space, time and actions. By using plans in one domain to focus the search in finer domains, we can speed up the overall process of having agents navigating complex virtual environments. This talk will briefly cover how navigation meshes can be automatically generated for path finding with the NEOGEN system. I will describe techniques to synthesize animations based on foot step trajectories for those scenarios that may require careful foot positioning. And finally I will cover rendering techniques focused on many animated characters in real time.

Short Bio:
Nuria Pelechano is an Associate Professor at the Universitat Politecnica de Catalunya. She obtained her Engineering degree from the Universitat de Valencia, her Master’s degree from the University College London, and her PhD from the University of Pennsylvania as a Fulbright Scholar in 2006. During her post-doc she worked with the Architecture Department at UPenn in several technology transfer projects on crowd evacuation. Prof. Pelechano is co-author of the books “Virtual Crowds: Methods, Simulation, and Control. Morgan & Claypool Publishers, 2008.” and “Virtual Crowds: Steps toward Behavioral Realism, Morgan & Claypool Publishers, 2015”. Nuria has over 30 publications in journals and international conferences on Computer Graphics and Animation. She has participated in projects funded by the EU, the Spanish Government, and USA institutions. Her research interests include simulation, animation and rendering of crowds, generation of navigation meshes, real-time 3D graphics, and human-avatar interaction in virtual environments.
