网上数学实验中函数的录入及可视化

INPUT AND VISUALIZATION OF A FUNCTION IN MATHEMATIC EXPERIMENTS ON INTERNET

为了解决网上数学实验中函数的录入及其图形可视化的问题,利用Java[1]和Java3D[2～6]技术给出了平面直角坐标函数的录入及可视化模块RightAngle2D、三维空间直角坐标函数的录入及可视化模块RightAngle3D和三维空间柱坐标函数的录入及可视化模块Pole3D。实验结果表明,所给模块具有较好的可视化效果和良好的人机交互性能。

The input of a function and the visualization of function＇s figure are problems on mathematic experiments based on Internet. In order to solve these problems,Java and Java3D provide the following modules：RightAngle2D-module：a module about the input and the visualization of a function＇s figure on two-dimensional coordinate plane;RightAngle3D-module ：a module about the input and the visualization of a function＇s figure on three-dimensional coordinate space;Pole3D-module：a module about the input and the visualization of a function＇s figure on three-dimensional cylindrical coordinate. The result of the experiment proved that the provided modules above had an excellent effect on both visualization of the function＇s figure and the Human-Computer interaction.
