There are currently a number of animation researchers that focus on simulating virtual crowds, but few are attempting to simulate virtual populations. Virtual crowd simulations tend to depict a large number of agents walking from one location to another as realistically as possible. The virtual humans in these crowds lack higher purpose. They have a virtual(More)
Over the past couple of decades, virtual humans have been attracting more and more attention. Many applications including, video games, movies, and various training and tutoring systems have benefited from work in this area. While the visual quality of virtual agents has improved dramatically, their intelligence and socialization still needs improvement. In(More)
While there continues to be exciting developments in research related to virtual characters, improvements are still needed to create plausibly human-like behaviors. In this paper, we present a synthetic parameterized memory model which includes sensory, working, and long-term memories and mechanisms for acquiring and retrieving memories. With the aid of(More)
Most crowd simulators focus on navigation and agents flow. In this paper, we present another perspective that concentrates on the overall distribution of virtual agents and uses psychological preferences for choosing goal locations. Both observation and published theory indicate that most people prefer to maintain their personal space as event spaces(More)
Seemingly since the inception of virtual humans, there has been an effort to make their behaviors more natural and more human-like. In additions to work on improving movement quality, there has been considerable research focused on creating more intelligent virtual characters. This paper presents a framework inspired by natural language constructs that aims(More)
