  • OSGFrameWork
    最近学习OSG,下载了FreeSouth大侠的一个MFC框架RambleSystem,自己学习了一下,新建了一个单文档程序,改了其中一些bug,和大家分享一下。单文档程序实现的功能非常简单,就是打开显示osg文件。不过仍存在一个问题,例如打开一些osg文件显示模型不理想,估计是视口设置有问题;另外打开一些osg文件出现内存泄露。(Recent study OSG, download heroes of an MFC framework FreeSouth RambleSystem, you learn a little, a single document, new procedures, some of which changed the bug, and share with you. Program realization of the function of a single document is very simple to open display osg file. However, there are still a problem, such as opening a number of osg file display model is not satisfactory, as the population estimate is set to have problems other osg files appear to open a number of memory leaks.)
