The applications of Web3D technologies in web teaching of engineering graphics

Abstract

Developing of teaching resources is the important and key components of Web teaching system of Engineering Graphics (EG). The multimedia resources of Web teaching on EG should be three dimensional (3D), interactive and suitable for the Web. These resources are different from that created by the technologies of dynamic Web page, Flash and stream media, etc. which have some disadvantages in constructing of real environment and interacting in real time. The development of Web3D technologies, main developing methods and process are presented in this paper. The application of Web3D technologies in designing and developing of Web teaching resources of EG is also studied. Some examples of the application of Web3D technologies, such as VRML, Java and Cult3D, are given in the paper. © 2012 Springer-Verlag.
