Abstract: In this paper, we introduced a novel method to simulate moving spectator crowd behaviours. Different from the common methods, we taken the emotional affections between spectators into consideration and calculated these affections by heat conduction model. The generation loops can be divided into three steps. We firstly exploited PAD space to build spectators' emotional states. Then we updated spectators' positions and generated their emotional affections by emotion transmission equations which were formulated from heat conduction equations. We called this step dynamic emotion transmission. At last, we mapped their emotions to actions. Using this algorithm, we can simulate more realistic crowd behaviours.
