最近開始學習用python進行科學計算三維視覺化，這個算是一個起步的小東西，貼出程式碼來mark一下這兩天的學習成果！

重難點在於安裝各種庫，呼呼，配置環境真的是一項大工程Orz。

安裝流程：

1、示例系統環境：

Windows10 64位 + Python3.6，在庫檔案所在目錄裡依次安裝：

VTK-7.1.1-cp36-cp36m-win_amd64.whl

numpy-1.12.1+mkl-cp36-cp36m-win_amd64.whl

traits-4.6.0-cp36-cp36m-win_amd64.whl

mayavi-4.5.0+vtk71-cp36-cp36m-win_amd64.whl

PyQt4-4.11.4-cp36-cp36m-win_amd64.whl

相關庫下載地址：http://www.lfd.uci.edu/~gohlke/pythonlibs/

2、示例系統環境：

MacOS 10.12.4 + Anaconda2（Spyder），在終端依次執行：

conda install vtk

conda install numpy

conda install traits

conda install mayavi

conda install PyQt

程式程式碼如下：
