在我决定改用更现代的教程之前,我一直在玩 NeHe 的 OpenGL 教程。然而,无论我选择哪个教程,我什至无法使用 VBO 和顶点数组渲染单个三角形。虽然即时渲染效果很好。
以http://ogldev.atspace.co.uk/www/tutorial03/tutorial03.html中的代码为例,将项目制作或复制到代码块以编译它会在我运行它时导致黑屏。
(请注意,本教程明确地将顶点数组的大小而不是字节数传递给 glBufferData 但即使修复了该错误,结果仍然保持不变)
我目前正在运行 Ubuntu(尽管我在同一台 PC 上运行 Windows 时遇到了这个问题)并且我目前使用的编译器是 GCC 4.7.2
我还认为我的视频卡(Mobility Radeon 4330)可能会因为根本不支持 VBO 而导致此错误,所以这是 glxinfo 的输出:
