In agent-based social simulation, crowd models are used to generate agent behaviors that should correspond closely to human crowds. Despite significant progress in this area, many existing crowd models do not yet account for important cultural factors in crowd behavior, and even more so, for mixed-culture crowds. Moreover, evaluation of crowd models accounting for culture is particularly diffic...

Within this paper we investigate the possibility to have a tool that counts individuals within a static crowd photo, which is taken with a camera included in a smart phone. These individuals form different density patterns. We explore ways to map and display the density information on top of the photo on the smart phone screen. This enables the user to have a fast estimate about how many indivi...

Crowd modeling is the study of crowd behaviours and has been used by, for example, safety engineers and architectural designers in assessing crowd movements in buildings under normal and emergency situations. However, many existing crowd models neglect how agents in the crowd explore the environment to find the most suitable or optimal path towards their destinations. Therefore, the main purpos...

There are various techniques for simulating crowds, however, in most cases the quality of the simulation is measured by examining its “look-and-feel”. Even if the aggregate movement of the crowd looks natural from afar, the behaviors of individuals might look odd when examined more closely. In this paper we present a data-driven approach for evaluating the behaviors of individuals within a simu...

This poster presents an efficient Animation Planning Mediator (APM) designed to animate virtual characters in real time for crowd simulation. The APM selects the most appropriate animation clip available for each character and modifies the skeletal configuration to satisfy constraints given by the virtual environment and crowd simulation (CS) module, such as eliminating foot-sliding. Using a re...

Crowd evacuation simulations are becoming a tool to analyze and assess the safety of occupants in buildings. Agent-based simulation provides a platform on which to compute individual and collective behaviors that occur in crowds. We propose a human behavior model in evacuation based on the Belief-Desire-Intention (BDI) model and Helbing’s agent behavior model. Human relationships affect the sta...

This paper presents a crowd simulation as a novel application of texture synthesis. The motion of autonomous agents is simulated using arbitrarily complex behavior, and captured to a 3D (i.e. animated) texture. The simulation is then expanded to a much larger number of agents using texture synthesis techniques. We make use of corner cubes for the synthesis, which are an extension to 3D of corne...

Crowd simulation for virtual environments offers many challenges centered on the trade-offs between rich behavior, control and computational cost. In this paper we present a new approach to controlling the behavior of agents in a crowd. Our method is scalable in the sense that increasingly complex crowd behaviors can be created without a corresponding increase in the complexity of the agents. O...
