Design and implementation of case in CG case teaching

This paper discusses some questions and the limitation in traditional teaching of computer graphics(CG), and a new teaching model-case teaching is presented according to the characteristic of CG, namely all theories or algorithms of CG are included in a synthetic computer scenes case. Then a concrete case is designed and implemented by Visual C++. Implementation steps for case teaching is introduced in detail, and then the multimedia teaching based on the new teaching model is researched. It has been proved that the efficiency and quality of teaching have been improved in practice.
