网人笔记，供初学者参考： （1）openGL超级宝典 /sweetdark/blog?catalog=386026 （2）有人对WEBGL javascript Three.js库的阅读和解释，写得很详细 如何用javascript写出高质量代码 /omni360/article/category/2511149/1 （3）javascript编程风格 /blog//04/javascript_programming_style.html (4) python基础 /suky520/article/details/25470923 （5）opencv for python configuration
---- python2.7.5和Opencv2.3.1配置安装python2.7.5安装Opencv2.3.1之后，将Opencv2.3.1安装目录下的..\build\python\2.7下的cv2.pyd和cv.py直接复制到x:\Python27\Lib\site-packages中即可，这样就可以使用python调用opencv了 /sunny2038/article/details/9080047 --- python中多行注释的实现 使用一对三个双引号弄成多行字符串就搞定了。如：""" 多行注释 多行注释 多行注释"""--- 安装 scikit-learn 库 $pip install -U scikit-learn 有时报错 error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat).
