c++ - 调用 glGenVertexArrays 时程序崩溃

Question

我正在尝试学习如何在 opengl 中编程并且正在使用 this tutorial .教程 1 工作正常，教程 2 崩溃并返回 1。

它失败了:

GLuint VertexArrayID;
glGenVertexArrays(1, &VertexArrayID);
glBindVertexArray(VertexArrayID);

具体来说:

glGenVertexArrays(1, &VertexArrayID);

有什么建议吗？也相关但从未解决OpenGL, FreeGlut and Glew crash with glGenVertexArrays call

Answer 1

看完这篇thread似乎在调用

glewExperimental = GL_TRUE; 
glewInit();

会解决问题。阅读 glewExperimental here , 它说

GLEW obtains information on the supported extensions from the graphics driver. Experimental or pre-release drivers, however, might not report every available extension through the standard mechanism, in which case GLEW will report it unsupported. To circumvent this situation, the glewExperimental global switch can be turned on by setting it to GL_TRUE before calling glewInit(), which ensures that all extensions with valid entry points will be exposed.

我不太确定这对 glGenVertexArrays 有何帮助，但值得一试
