Manim: 一个数学可视化的动画引擎
官网：https://3b1b.github.io/manim/index.html
名词解析
- python3.7是python语言的解释器, 运行python程序的环境必备品. 这个没啥说的,大家都能懂. 虽然官方建议3.7,但是我用3.8发现也没问题.考虑未来的历史进程,大伙最好还是装3.8的版本吧.
- pip ,用来管理包(又叫"库").python的伟大之处在于其免费(点赞也不要钱). 所以人人可用, 大家都用, 就有人们开发出来了各种强大的python库.使用这些库我们就可以用少量代码实现人脸识别之类的高级功能. 解放了人类的劳动力到更高级的工作上,而不是天天写重复的低级代码. 而这些库, 一般就是用pip来安装的. 现在介绍pip,后文将教大家咋用. 如果你学过python的话,应该已经会用了.
- FFmpeg, 著名的开源视频流处理内核. 内核代表这东西几乎无法独立运行. 但是它却可以作为其他程序的心脏去工作.比如作为VLC, 或者一些录屏软件,剪辑软件的内核. Manim的视频渲染就是基于它的接口的.
- sox,一个小巧的用于处理音频的软件.
- TeX宏集. 对于大部分人来说可能比较陌生. 这个是用来用编程的方式输出高质量论文的一种语言/程序. 尤其擅长渲染复杂的公式. Manim需要TeX环境处理公式和文字. 不像Microsoft office word 那样的所见即所得文字处理程序, TeX通过代码描述文章,然后直接渲染出来可视化的效果.比如MiKTeX直接输出pdf文档,Manim直接输出图片或者视频.

检验Manim是否安装成功
1.创建一个名为example.py 的文件，把以下内容复制进去
from manim import *
class SquareToCircle(Scene):
def construct(self):
circle = Circle()
square = Square()
square.flip(RIGHT)
square.rotate(-3 * TAU / 8)
circle.set_fill(PINK, opacity=0.5)
self.play(Create(square))
self.play(Transform(square, circle))
self.play(FadeOut(square))
2.在刚才创建的example.py所在的文件夹里边右键运行【在终端打开】
执行遇到问题
no module named “manimlib”
需要将该文件放到软件安装的目录下，比如，本次软件安装在自己创建的manim文件夹中
【manim】导入库时出现ModuleNotFoundError: No module named‘manimlib.XXX‘解决方法
