In this work, we present a massive simulation of a behavioral model using graphics hardware. In particular we took a well established model to simulate complex flocks and we focused our attention on its implementation using techniques to manage efficiently large amount of data. Using the recent programmability of GPUs and recent extensions of computer(More)
Co-located collaboration in classroom is the topic we tackle in this paper. We present COFFEE a tailorable collaborative environment that is designed for interactive, co-located (i.e. Face2Face) collaboration in classroom. We present the requirements for tailorability that have driven our design, CoFFEE architecture, some tools that have been deployed and(More)
The Treeview control is the traditional way of visualizing hierarchical information in user interfaces, but in situations such as managing bookmarks in browsers, more general classifications may be more appropriate than hierarchies. We have developed a component called EulerView which is an extension of Treeview, with a similar look and feel, addressing(More)
We focus on agent-based simulations where a large number of agents move in the space, obeying to some simple rules. Since such kind of simulations are computational intensive, it is challenging, for such a contest, to let the number of agents to grow and to increase the quality of the simulation. A fascinating way to answer to this need is by exploiting(More)
In this paper we study state-of-the-art technologies to design interactive and cooperative 3D environments that are based on videogame 3D engines. We provide, first, a categorization of videogame 3D engines from the point of view of their usage in creating interactive 3D worlds and show a comparison of the most important characteristics. Then, we show an(More)
Co-located collaboration in classroom is the topic we tackle in this paper. In particular we will describe how CoFFEE implements this kind of collaboration. CoFFEE is an extensible platform on which to implement different collaborative tools. Every tool renders a different kind cooperation between users. In this paper we will also provide further details in(More)
We present the theoretical foundation, the design and the implementation of a library, called EulerVC to interactively handle Euler diagrams for the purposes of resource management. Fast on-line algorithms to interpret wellformed diagrams have been developed utilising a new notion of marked points to keep track of the zone sets. The interface allows the(More)
Agent-based simulation models are an increasingly popular tool for research and management in many, different and diverse fields. In executing such simulations the " speed " is one of the most general and important issues. The traditional answer to this issue is to invest resources in deploying a dedicated installation of dedicated computers. In this paper(More)
