说明：  根据OSG3.01源代码，采用Doxygen工具生成的帮助文档，只可惜源代码注释太少，有的函数压根没注释，几乎所有的函数都没有参数以及返回值的注释（更让人汗颜的是，包含文件木有.h后缀，需要修改后缀名，doxygen才能搜索到~），别怪我提供的信息少，只能说明当初写代码的都是高手，不需要神马注释~~相比另一个开源引擎-OGGRE，个人更偏爱于OGRE，至少源代码注释很详细，根据注释都能猜测到作者当初的设计初衷~ 最后希望该文档能给苦苦寻找OSG API文档的同学们提供点帮助
(According OSG3.01 source code using Doxygen tool to generate help files, but unfortunately too few source code comments, and some did not even comment function, almost all of the function parameters and return values are no comments (even more ashamed of that, wood .h include file suffix, you need to modify the suffix name, doxygen can search ~), less blame me information provided, only that when he started writing the code are masters, God does not need to comment ~~ horse compared to another open source students engine-OGGRE, individuals prefer to OGRE, at least the source code comments in great detail, according to comments can guess the author designed the original of the document- the last hope to give struggling to find OSG API documentation provide some help)
