通过一个图形用户界面（GUI）演示常见的三维函数图形，演示sphere函数曲面、变化的cylinder曲面绘图、变化的多峰函数。并且可以对以上三个函数进行加网格，坐标边框，以及对函数进行色度变换。-Through a graphical user interface (GUI) presentation function common three-dimensional graphics, presentation function sphere surface, changes in cylinder surface mapping, change the multi-peak function. And the above three functions can be added to the grid coordinates border, as well as the chroma transform function.
