We can get three cubic spline function based on regular volume data by extending spline interpolation function from two-dimensional space to three-dimensional space. If we solve the three cubic spline function directly, Ill-posed solution may be generated and calculation work is very large. Calculation method of product calculation principle is proposed in this article. Three variables problem will be converted to one variables problem. An instance in geological field is developed through the method of object-oriented analysis and design and three cubic spline is implemented in this article. The instance is a three layer structure application and the data communication among the modules is solved through STL. So the application has strong maintainability and extensibility. All in all, this article is possible to provide some reference for further research in this field.
