无法将简单的网格物体加载到OpenGL中

我需要在Visual Studio 2010的OpenGL代码中导入3D对象网格。我是OpenGL的新手，所以我一直在学习以下教程（编号7）：

http://www.opengl-tutorial.org/beginners-tutorials/tutorial-7-model-loading/

现在，本教程使用简单的代码而不是库来导入“ .obj”文件。使用过本教程的人会知道，本教程的创建者提供的“ cube.obj”效果很好。但是，当我尝试加载自己的简单立方体网格时，程序会通知我“我们的简单解析器无法处理.obj文件。请尝试使用其他选项进行导出”。

我认为这是代码问题，然后转到他的Assimp教程：http : //www.opengl-tutorial.org/intermediate-tutorials/tutorial-9-vbo-indexing/

这次，提供了“ Suzanne.obj”作为示例。再一次，每当我尝试将自己的对象导出到代码中时，该程序现在都崩溃，并显示“ Visual Studio已停止工作”。这仅在我导出的对象中发生。为了缩小问题原因，我使用了教程7和教程9中提供的“ cube.obj”，并且效果很好。因此目前看来，问题出在从Blender导出对象。

我已经遵循了教程7中有关在导出对象时需要检查哪些选项的所有说明。但是，值得注意的是，我导出的对象的“ .obj”代码显示在一行中，没有任何换行符。这是我导出的简单立方体网格物体的obj代码：

# Blender v2.73 (sub 0) OBJ File: 'ROOM.blend'

在调试崩溃的程序时，发生以下异常：

tutorial09_AssImp.exe中0x00007FF76255E2D5的未处理异常：0xC0000005：访问冲突读取位置0x0000000000000000。

调用堆栈如下：

tutorial09_AssImp.exe！aiVector3t :: aiVector3t（const aVector3t＆o）第67行C ++ tutorial09_AssImp.exe！loadAssImp（const char * path，std :: vector>＆index，std :: vector，std :: allocator

＆顶点，std :: vector，std :: allocator＆uvs，std :: vector，std :: allocator＆normals）149行C ++ tutorial09_AssImp.exe！main（）92行C ++

此外，在vector3.h中会发生异常，如下所示：

显然，导出模型时我做的不正确。我可能做错了什么？我缺少步骤了吗？
