In all ways of perception, vision is the main channel of getting environmental information for intelligent virtual agent
(IVA). Reality and real-time computation of behavior simulation of intelligent objects in interactive virtual environment
are required. This paper proposes a new method of getting environmental information. Firstly visual images are
generated by setting a second view port in the location of viewpoint of IVA, and then the target location, distance,
azimuth, and other basic geometric information and semantic information can be acquired based on the images.
Experiments show that the method gives full play to the performance of computer graphic hardware with simple process
and higher efficiency.
