Abstract
In the research of emotional simulation, this paper introduces an emotional model involving many factors that affect the emotion, it integrates some existing influential factor such as outside stimulus, decay of emotion, cognitive and non-cognitive factors, personality, subconsciousness and so on, in addition, it also considered some of the virtual humans' subjective reasons, such as the behaviors, vision and values. At last, a crowd scene is simulated using this model, which indicates that this model can reflect many different emotions appropriately.
