## Drawing anything with Fourier Series using Blender and Python

Recently, in the Fourier Series chapter of “Coding Druid”, I practiced the visualization of Fourier Series and demonstrated the periodic square wave curve, which can be decomposed into a series of sine wave curves: Above is Python (Blender) version. There are JavaScript (React) version, and Unity version. “Coding Druid” series is my horizontal programming practice notes, each part around a topic like mathematical, physics, electronic, graphics, sound, etc., implemented in several programming languages. This time I’m try to draw something with Fourier

## Using Blender to run Python and visualizing the Fourier Series

“Coding Druid” series is my horizontal programming practice notes, each part around a topic like mathematical, physics, electronic, graphics, sound, etc., implemented in several programming languages. Coding DruidPart: MathChapter: Fourier SeriesSection: Python (in Blender) In this Chapter, I have visualized Fourier Series separately using JavaScript (React): and Unity: This section is Python again. Playground options In the note Sine function visualization using Python I used Jupyter Notebook as Python IDE/Playground.Jupyter is a great online IDE for Python. You can basically do

## Sine function visualization using Python

“Coding Druid” series is my horizontal programming practice notes, each part around a topic like mathematical, physics, electronic, graphics, sound, etc., implemented in several programming languages. Coding DruidPart: MathChapter: Trigonometric FunctionSection: Python In the previous two sections, I visualized Trigonometric function (Sine and unit circle) by MaxMSP and JavaScript (React): Trigonometric Function Visualization Using MaxMSP Sine Function Visualization Using JavaScript (React) This time I use Python to implement it. For the quick goal,

## flex与django|python通信，通过pyamf

pyamf官网上推荐了一篇中文howto（1，2），介绍django与flex通信，通过pyamf（一个python的开源api，专门针对amf协议）。其中有个小问题，就是destination的设置。 共有三处会用到该属性（这篇中文howto只提到了两处），我的代码片段如下： 1 flex：<mx:RemoteObject id=”djangoService” destination=”destinationFucker” showBusyCursor=”true”/> 2 services-config.xml： <destination id=”destinationFucker”> <channels> <channel ref=”fuckChannel”/> </channels> </destination> 3 amfgateway.py: usersGateway = DjangoGateway({ ‘destinationFucker.testFuck’:testFuck, ‘destinationFucker.testArrayFuck’:testArrayFuck }) 深红色的python部分，在原文中是没有destination的（当然原文中也没有fu*k）。 我不知道原文的example是如何测试的，至少我滴环境下（django自带server，无数据库）如果在python（或django）的方法前不加destination（即直接’testArrayFuck’:testArrayFuck ），flex是无法找到远程方法testArrayFuck的。（后注：后来发现原example无效是因为pyamf版本有更新） flex的RemoteObject，天生出来是与java后台相亲相爱的 ，在java中，destination对应的可以是该class名，即： class destinationFucker { public function testArrayFuck(){} } 而在python中，至少这个example中米有class，所以必须在映射方法testArrayFuck时加上destination才能找到“destinationFucker.testArrayFuck”。 那么客户端flex及services-config中不写destination行不行涅？ 答案貌似是“不行”，如果在RemoteObject及services-config中去掉destination，运行时会找不到destination而报错。 那么客户端flex及services-config中destination id=””行不行涅？ 答案也貌似是“不行”，在services-config中destination的id不接受””。至少在flex默认配置下这样是不行滴。 另外，上边举的那个java的例子，其实我猜的，因为从没用java试过 ^_<
