The use of 3D virtual technology in cultural transmission has been more and more innovative and popular in the recent years. Meanwhile, with the high interactivity, experience of virtual technology deeply rooted in the people's hearts, the use of 3D virtual world in cultural transmission shows an evident advantage. Through scene construction and intelligent interaction in a 3D virtual world environment, we developed the project “Confucius' Journey”. And considering the problems in such applications, such as the lack of interaction and reduced effectiveness in representing the application purpose, we explored interactive objects and virtual human technology. In addition, we can verify the advantage of using the 3D platform via the experimental results.
