Research of Virtual Human Perception Model and Behavior Planning Based on Virtual Teaching Environment

With the extensive application of virtual reality technology,the study of the virtual human in the virtual environments has also become a research focus. This paper discusses the virtual human perception model and create a virtual spatial database query information,combine the AABB collision detection algorithm,complete the construction of virtual human perception model and the virtual behavior planning in the teaching environment,the virtual human intelligent behavior is realized preliminarily in the virtual teaching environment.
