ABSTRACT
The cutting of three-dimensional (3D) geometric shapes is an important issue in solid geometry, and it has indispensable functional requirements for 3D Dynamic Geometry Software (DGS). There are some problems of cumbersome steps and poor experimental effect when constructing the cutting of 3D geometric shapes in many existing 3D-DGS. The parameters-based 3D cutting method for DGS is presented in this paper. Firstly, we build a core model of the parameters-based 3D cutting function. Secondly, when processing the core calculation of the cutting function, we mainly calculate the relevant values of 3D geometric shape and cutting planes in two cases. One is parallel cutting, and the other is series cutting. Finally, an experimental result show that the continuous change of the cut shapes, greatly optimizing the cutting affect, and simplifying the construction steps of 3D cutting can be realized by the 3D cutting function designed in the paper. At present, more and more people use 3D cutting function to create intuitive and vivid dynamic geometry resources.
