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)
In this paper we study the technologies that are available for interactive and cooperative 3D environments. In particular , we describe how state-of-the art videogame 3D engines can be fruitfully used to create interactive 3D worlds that leverage on the photorealistic quality of the graphics and the high level of immersive navigation. We provide, first, a(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 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)
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)
—Massive Multiuser Virtual Environments (MMVEs) are rapidly expanding both in the number of users and complexity of interactions. Their needs of computational resources offer new challenges for the computer scientists. In this paper we present some ideas on the implementation of a Massive Simulation Environments, a particular MMVE, distributed over a(More)
