卡支持OpenGL 4.1，但线程上没有GL4实现？

当我运行我的测试JOGL应用程序时，它说当我的系统根据OpenGl Extensions Viewer支持OpenGL 4.1时，线程上只有GL2可用。卡支持OpenGL 4.1，但线程上没有GL4实现？

有没有人看到任何明显的为什么只有GL2会在线程中被支持？

我使用的是2015年中的Macbook Pro，配备了Intel Iris和AMD Radeon R9显卡。

这是一本书[计算机图形学的编程在OpenGL与Java]的第一个练习。 4

Java版本：Java8

JOGL版本：2.3.2

GlueGen版本：2.3.2

这很有趣，'glxinfo'返回只支持OpenGL 2.1（OpenGL版本字符串：2.1 ATI-1.42.15），但根据Apple（https://support.apple.com/zh-cn/HT202823），4。1应该被支持。 – collenjones

事实证明，OSX回落到OpenGL 2.1，因此您需要自己设置核心配置文件。

$ glxinfo | grep OpenGL 
OpenGL vendor string: ATI Technologies Inc. 
OpenGL renderer string: AMD Radeon R9 M370X OpenGL Engine 
OpenGL version string: 2.1 ATI-1.42.15 
OpenGL shading language version string: 1.20

我能够通过将GLCapabilities传递给GLCanvas构造函数来设置核心版本（OpenGL 4.1）。

这里是新的，固定的构造函数：

public Code() { 
    setTitle("Chapter 2 - program1"); 
    setSize(600, 400); 
    setLocation(200, 200); 

    // This was the fix 
    GLProfile glp = GLProfile.getMaxProgrammableCore(true); 
    GLCapabilities caps = new GLCapabilities(glp); 
    myCanvas = new GLCanvas(caps); 

    myCanvas.addGLEventListener(this); 
    this.add(myCanvas); 
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    setVisible(true); 
}

这不是一个真正的修复。使用JOGL时选择一个配置文件是一个好习惯，它避免依赖于默认配置文件。 – gouessej

对于Mac上运行书上的例子，我已经把这个网站上的说明：http://athena.ecs.csus.edu/~gordonvs/errataMac.html

总之，你需要：

确保您安装了最新的Java SE
将相关的JOGL库放入Sys tem/Library/Java/Extensions（以上网站列出了所需的具体内容）
添加上述Julien代码（谢谢！）
将着色器的版本号更改为410（或任何Mac支持）
在使用纹理的例子中，在着色器来glUniform1i适当的（）调用的Java应用程序4.1版本）取代结合布局预选赛（兼容

如果有更多的特质被识别，我会将它们添加到网站上的说明中。

不要将任何库放入System/Library/Java/Extensions中，这是一种不好的做法，因为扩展机制将从Java 1.9中移除，并且会影响系统中的所有应用程序和applet，因为存储在此目录中的库在应用程序的类路径中的库。例如，假设您将JOGL 2.3.2放入此目录，而特定应用程序需要JOGL 2.4，则可能无法运行，因为JOGL 2.3.2将首先加载。这种机制很麻烦，容易出错，请不要使用它。 – gouessej

我建议你阅读：https：//blogs.oracle.com/java-platform-group/planning-safe-removal-of-under-used-endorsed-extension-directories http://openjdk.java.net/jeps/220 http://docs.oracle.com/javase/8/docs/technotes/guides/extensions/index.html“此功能已被弃用，将在未来版本中删除” – gouessej

对不起 - 我们错误地认为Apple的扩展文件夹会继续。看起来你是对的。猜猜这意味着我的第二个项目符号应该说是将jar添加到您的类路径中，或者使用-cp选项将它包含在java命令行中。我将修改该页面。 –
