大家下午好呀

不知道有没有人和小编一样

在看到别人画的3D图片时

觉得很高级，很酷炫呢

今天小编就和大家分享最近学到的技能啦，赶紧@你的小伙伴一起学习吧！

Good afternoon everyone

I don’t know if anyone is the same as Me

When seeing 3D pictures drawn by others

I feel very advanced and cool

Today, the editor will share with you the skills learned recently. Get you friends to study with you.

前言previous remarks：‍

学术科研中，用于绘图的软件很多，今天小编介绍的软件是Mathematica，这个软件是由沃尔夫勒姆研究公司（Wolfram Research Inc.）研发的。

数学软件是现在科研工作者的必备的工具，Mathematica最显著的变化是允许自由形式的英文输入，而不再需要严格按照Mathematica语法，这类似于Wolfram|Alpha搜索引擎。

Mathematica8允许用户按照自己习惯的思考过程输入方程式或问题，最令人激动的部分是软件不是逐行执行命令，而是能理解上下文背景。

In academic research, there are many softwares used for drawing. The software introduced by the editor today is Mathematica.

Mthematica software was developed by Wolfram Research Inc. (Wolfram Research Inc.).Mathematics software is now an indispensable tool for scientific researchers. The most significant change in Mathematica is to allow free-form English input instead of strictly following Mathematica grammar, which is similar to the Wolfram|Alpha search engine.

Mathematica 8 allows users to enter equations or questions in accordance with their habitual thinking process. The most exciting part is that the software does not execute commands line by line, but understands the context.

学习之前，我们需要做以下工作Before learning, we need to do the following:

1.了解常用的三维绘图函数

Understand commonly used 3D drawing functions

2.了解三维绘图函数中常用的可选项

Understand the commonly used options in 3D drawing functions

Plot3D函数有许多可选项可以用来修饰三维图形的外观，可以借助于可选项改变图形的外观，以便于观察

The Plot3D function has many options that can be used to modify the appearance of three-dimensional graphics. You can change the appearance of the graph with the help of optional options for easy observation.

3.了解典型的ViewPoint值

Understand typical ViewPoint values

案例展示Application case display：

solution：

In[1]:= Plot3D[Sin[x*y],{x,0,2Pi},{y,0,2Pi},AxesLabel->{“x”, “y”, “z”}]

Out[1]= -SurfaceGraphics-

In[2]:= Show[%,ViewPoint->{－1,-1,2}]

Out[2]= -SurfaceGraphics-

是不是很酷炫

下面上“双曲面”感受一下（加强学习）

In[1]:=ParametricPlot3D[{Cosh[u]*Cos[v],Cosh[u]*Sin[v],u},{u,0,Pi},{v,Pi,Pi},AxesLabel->{“x”, “y”, “z”}]

Out[1]= -Graphics3D-

一个高颜值的单位双曲面3D图就做好啦

是不是很简单！

A high-value unit hyperboloid 3D drawing is ready, isn't it very simple!

拓展练习

好学的同学应该会问：想要展示两个方程围成的图形，应该怎么做呢？

废话不多说，上图！

The eager student should ask: What should I do if I want to show the graph enclosed by two equations?

cut to the chase, post the picture!

由于篇幅有限

今天的分享就到这里啦
