其实最好的教程是OSG自带的例子，在资料文件中会有OSG的相关的例子，里面大多数的例子都很有实用价值，我们学习OSG都是从它而来，而且例子的难度有大有小，方面极广，坦而言之，如果里面的例子都看通了，对OSG的理解会上升很多个层次。在bbs.osgChina.org上有Hesicong为部分例子做的注释(In fact, the best course is OSG's own example, the document will have OSG relevant examples, which most of the examples are very practical, we are learning OSG that come from it, and the example of the difficulty of big and small, very wide, frankly speaking, if there are examples of see through, the understanding of OSG will rise a lot of levels. On bbs.osgChina.org, there are Hesicong annotations for some examples)
