在電腦動畫的領域裡,模擬人群的應用逐漸在電 玩、電影及動線規劃等應用上,扮演著重要的角色。 過去的人群模擬研究著重於碰撞避免及隊形維持,對 於人群的互動機制則較少貢獻。我們利用 bottom-up 的 方式,建立一個即時人群模擬的平台,特別在於人群 中的 agent 因擁有個別化的虛擬力參數而具異質性,並 可藉由彼此訊息的傳遞,達到群體運動的可控制及客 製化(customization)為目的。我們在此論文中將以動畫 實例說明此人群模擬模型的有效性,並在 3D 動畫軟體 中具體呈現。

In the case of emergency situations, robotic systems can play a key role and save human lives in recovery and evacuation operations. To realize such a potential, we have to address many scientific and technical challenges encountered during robotic search and rescue missions. This paper reviews current state-of-the-art robotic technologies that have been deployed in the simulation of crowd evac...

ABSTRACT: To prevent crowd accidents in large-scale facilities that are available to the general public, it is important to share information on safety measures among organizers, the police, the fire department, and government officials. In this study, we present a crowd simulation system that is capable of sharing visual information on the estimated flow of the crowd and that can be used when ...

This paper presents a parallel real-time crowd simulation method based on a hierarchical environmental model. A dynamical model of the complex environment should be constructed to simulate the state transition and propagation of individual motions. By modeling of a virtual environment where virtual crowds reside, we employ different parallel methods on a topological layer, a path layer and a pe...

We present a platform for creating immersive 3D games including a new interface for navigating through virtual scenes. One innovative part of this application is a crowd simulation with an emergent behaviour of virtual characters. While the users has to move very quickly through a crowd of nearly two hundred virtual characters he is supported by a precise, fast operating, and unobtrusive naviga...

This paper presents a scalable approach to crowd simulation that can generate complex and varied simulations by using multiple types of individuals in a crowd. Efficiency is attained by using a situation-based approach where an individual agent adopts behaviors according to its situation, which corresponds to a subspace of the universe.

This paper proposes a spatial activity-based modeling approach and applies it to pedestrian crowd behavior simulations. Compared to conventional pedestrian crowd models where pedestrians make movement decisions in a time-based manner, the spatial activity-based pedestrian crowd model allows a pedestrian to make decisions only when needed, that is, when there is significant change in the pedestr...

This paper presents an insight of the review on crowd behaviour in panic situation and crowd modelling. The crowd behaviour discussed in this paper will observe the state-of-the-art in crowd reaction pattern during emergency outbreak in which the model and simulation will be constructed and considered based on the cited papers. Additionally, the sociological behaviour of individual in the crowd...
