| Abstract: | The paper mainly introduces the three methods of projection transformation , namely the changing surface method, rotation method and oblique projection method. And analyses the characteristics of three methods of projection transformation in descriptive aspects. And points out that the projection transformation method is usually used to solve some pictorial, graphic problems that orthographic projection method can not solve. Studies the descriptive geometry graphic type of each method to solve the problem. Through comparative study, summarizes the most suitable type of problem that each projection method can solve. The most suitable type of problem solving refers to the problem solving process when using some methods is not only quick but also simple. |
