Java 在jogl中对立方体进行纹理处理会产生黑屏

我试图用加尔文和霍布斯的图像在jogl中制作一个立方体纹理。我在网上看到的每一个消息来源都说有这条线

gl.glEnable（GL2.gl\u纹理\u 2D）在那里。但是，当我添加它时，我会看到一个黑屏。当我把它注释掉时，屏幕上会出现一个立方体。任何帮助都是受欢迎的，因为我已经在谷歌上搜索到了这个问题，并尝试了无数的解决方案。我的源代码如下

我已经在这里回答了您：gl.glMatrixMode（GL2.gl_纹理）在您的情况下是无用的。只有第一个三角形有一些纹理坐标。对于其他三角形，应在glBegin（）和glEnd（）之间添加一些纹理坐标。使用搜索引擎没有帮助，你需要花一些时间学习OpenGL的概念。我知道你这样做了，这个答案很有帮助。我只是在同一个问题上寻找不同的观点。这没什么错。但你的回答确实有帮助。使用google和您指导我的存储库帮助我理解OpenGL的概念。非常感谢。
