三维曲线曲面比较演示系统程序设计 设计一个图形用户界面（GUI）演示常见的三维函数图形，至少包含“三维绘图” 、“选项” 、“退出”等菜单，三维绘图的包括：参数方程x=e-t/20cos(t), y= e-t/20sin(t),z=t其中t 为0到2π、参数方程x=t,y=t2,z=t3其中t为0到1之间（在同一图形界面中分别绘制它们的三维曲面和三维曲线图）。“选项”菜单主要包括：网格开关，图例开关，坐标边框开关，色度空间选择菜单，曲线颜色菜单。(Comparison of three-dimensional curves and surfaces demonstration system design to design a graphical user interface (GUI) presentation function common three-dimensional graphics, at least three-dimensional graphics, options , Exit menu, etc., three-dimensional graphics, including: parameters of equation x = et/20cos (t), y = et/20sin (t), z = t one of t from 0 to 2π, parametric equation x = t, y = t2, z = t3 which t is between 0-1 (in the same graphical interface, respectively, three-dimensional mapping of their surface and three-dimensional curves). Options menu includes: grid switches, legend switches, coordinate frame switch, color space selection menu, menu color curve.)
