Simulation of Pedestrians in Computer Animation

Simulation of pedestrians in computer animation is a challenging and interesting subject for many fields. A behavior animation model of pedestrians is presented in this paper. A virtual pedestrian is regarded as an agent with built-in cognitive model that integrates sense, perception, emotion, behavior, etc. together. Psychology-based navigation method is introduced in this paper by Gibson´s theory of affordances. A virtual pedestrian can perceive these affordances directly; some semantic information is set up for special area in virtual environment to guide the movement of a virtual pedestrian, scene octree can simulate the perception of a virtual pedestrian for space. A behavior animation system of pedestrians is set up on PC, and emotional walking is realized by motion blending
