Currently, there are many two-dimensional Dynamic Geometry System(DGS) which reached a high level of development, while the development of three-dimensional DGS is at its beginning stage and there are only a few 3D DGS existed for solid geometry education, especially in China. These 3D DGS mainly used the plotting module as the core, but it brings some deficiencies such as can't precisely operate and control of figures, geometric and algebraic module can't link closely, the feature of dynamic displaying the changing process is not demonstrate completely. In order to solve these problems and ai...
