Simulating Crowd Motion with Shape Preference and Fuzzy Rules
نویسندگان
چکیده
Crowd simulation is becoming indispensable in computer games and animations. Several approaches to this problem have succeeded in generating flocking behaviors with virtual forces but it remains difficult to manipulate the collective behaviors of a crowd to respect certain desired shape. In this paper, we propose a crowd simulation system that can generate a feasible path taking the crowd to the goal while maintaining a user-specified shape as much as possible. The system consists of two key components: a path planner that can search for a feasible path for a region of flexible shape and a local motion controller based on three classes of fuzzy rules for generating desired agent behaviors. We will demonstrate the implemented system with several examples to show the generated path and the corresponding crowd motions adhering to a desired shape. Keyword: Motion planning, computer animation, multi-agent system, crowd simulation

Fuzzy logic approach and sensitivity analysis for agent-based crowd injury modeling
A crowd is a group of people attending a public gathering with some joint purpose, such as protesting against the government or celebrating an event. In some countries, these kinds of activities are the only way to express public displeasure with their government. The government’s reactions to such activities may or may not be tolerant. For this reason, such situations must be eliminated by rec...

In this paper, we present a data-driven method for crowd simulation with holonification model. With this extra module, the accuracy of simulation will increase and it generates more realistic behaviors of agents. First, we show how to use the concept of holon in crowd simulation and how effective it is. For this reason, we use simple rules for holonification. Using real-world data, we model the...

We present a system for simulating crowd behavior in emergency scenarios, specifically, the evacuation of buildings. We use a combination of techniques from robot motion planning, collision detection and response, particle systems, and group behavior. Our method initially builds a roadmap of the environment using PRMs, and computes the path to closest exits on the roadmap. The virtual agents mu...
متن کاملHierarchical Model for Real Time Simulation of Virtual Human Crowds
This paper describes a model for simulating crowds of humans in real time. We deal with a hierarchy composed of virtual crowds, groups and individuals. The groups are the most complex structure that can be controlled in different degrees of autonomy. This autonomy refers to the extent to which the virtual agents are independent of the user intervention and also the amount of information needed ...
