20170622使用VTK库画一个立方体

最近开始学习用python进行科学计算三维可视化，这个算是一个起步的小东西，贴出代码来mark一下这两天的学习成果！![大笑][laugh.gif]

重难点在于安装各种库，呼呼，配置环境真的是一项大工程Orz。

安装流程：

1、示例系统环境：

Windows10 64位 + Python3.6，在库文件所在目录里依次安装：

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

相关库下载地址：http://www.lfd.uci.edu/~gohlke/pythonlibs/

2、示例系统环境：

MacOS 10.12.4 + Anaconda2（Spyder），在终端依次运行：

conda install vtk

conda install numpy

conda install traits

conda install mayavi

conda install PyQt

程序代码如下：

Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) \[MSC v.1900 32 bit (Intel)\] on win32
