A simulation of a large population behavior based on netlogo
ABSTRACT
With the development of Simulation in digital human behavior,especially the rapid promotion of its application, large-scale population behavior simulation technology has become a new research focus in the field of virtual human synthesis.Large-scale human motion simulation is to study the characteristics and regularity of population movement. In various environments,build model Simulation of large-scale population movement,and show large-scale population movement by three-dimensional way realistically in the computer's space of generation. Large-scale population behavior simulation technology provides the crowd motion analysis and demonstration tool, the field of application is quite extensive.
Netlogo is an Agent Based Modeling(ABM)utility.The mechanism and main

functions are introduced and experiment is illustrated through an example.In allusion to the method of driving the virtual crowd's behavior,the next action state was described through designing the action attributes.Furthermore,the event response mode of the virtual crowd's action simulation with the production rule is realized.In the end,this behavior model and simulation method are applied to the three-dimensional simulation of crowd urgent escape and good result is obtained.
Key words:virtual crowd;crowd simulation;behavioral research;artificial vision;path planning
