An exploring research of intelligent virtual human's perception model

The perceptive function is the foundation of virtual human behavior modeling in the research of the intelligent virtual human autonomous behavior model.How to exactly construct human's perceptive function is a challenge.This paper presents how to set up a 3D virtual scene and virtual human models,on the basis of which emphasizes a realized method of virtual human's perception model.In the method,we construct a spatial inquiry table to manage and inquire the information of the scene.Virtual human can access information through the table anytime and the collision detection algorithm,in the light of which to judge whether there is any barriers,and to take decision to the next action. It is primarily realized the perception to the virtual environment.
