【 摘 要 】

In the article is reported a method of constructing the model of three-dimensional parametric solids free-form and their description using Bezier curves and surfaces. There are shown the equations of solid patch that bounded curves and surfaces cubic Bezier. The experiment was carried on an octagonal carcass of curved solid patch. Computer experiment showed that the method works well and correctly determines the position of the external and internal surfaces of both the initial condition, and under deformation of the solid shape's with the aid of control points. This method makes easyly controlling the shape and completely describes the behavior of the intermediate surfaces inside of the simulated object's solid. The proposed method can be used for numerical simulation of multilayer structures.
