如果我对这个问题的措辞不佳，我深表歉意。
我是否可以在任何地方找到 OpenGL/WebGL 函数 列表以及它们关联的目标？例如，为了调用glDrawElements()，缓冲区必须绑定到GL_ELEMENT_ARRAY_BUFFER 目标。而要调用glBufferData()，缓冲区必须绑定到多个目标之一，包括GL_ARRAY_BUFFER、GL_ELEMENT_ARRAY_BUFFER、GL_UNIFORM_BUFFER等...
解决这个问题的另一种方法是，是否有目标列表及其启用的功能？
我已经下载了 OpenGL 3.0 ES 文档文件，并且我非常确信我需要的所有信息都包含在其中。但它分布在约 280 个文件中，我知道我会错过很多实例。我一定忽略了一些东西，因为在尝试掌握“目标”的概念时，这似乎是 OpenGL 的一个重要方面。

在等待了一段时间后，我决定使用从递归 grepping 参考手册中获得的信息来提交我自己问题的答案。
这肯定是部分列表。大概有些错误。如果您发现任何遗漏或错误，请随时编辑和更正。
如果有人可以提交更好、更准确的答案，我将很乐意接受并表示感谢。
