在本节中，我们将学习JOGL提供的类。通过这些类，我们可以在Java代码中添加OpenGL的功能。
以下是JOGL提供的重要课程：-
GLCanvas和GLJPanel类是实现GLAutoDrawable接口的GUI类，并用作Open GL命令的绘图表面。
| Constructor | Description |
|---|---|
| GLCanvas() | It creates a new GLCanvas component with default set of OpenGL capabilities by using the mechanism of default OpenGL capabilities on the default screen device. |
| GLCanvas(GLCapabilities cap) | It creates a new GLCanvas component with requested set of OpenGL capabilities by using the mechanism of default OpenGL capabilities on the default screen device. |
| Method | Description |
|---|---|
| void addGLEventListener(GLEventListener listener) | It adds GLEventListener to this drawable. |
| void display() | It causes OpenGL rendering for GLAutoDrawable interface. |
| void removeGLEventListener(GLEventListener listener) | It removes GLEventListener to this drawable. |
| Constructor | Description |
|---|---|
| GLJPanel() | It creates a new GLJPanel component with default set of OpenGL capabilities by using the mechanism of default OpenGL capabilities on the default screen device. |
| GLJPanel (GLCapabilities cap) | It creates a new GLJPanel component with requested set of OpenGL capabilities by using the mechanism of default OpenGL capabilities on the default screen device. |
| Method | Description |
|---|---|
| void addGLEventListener(GLEventListener listener) | It adds GLEventListener to this drawable. |
| void display() | It causes OpenGL rendering for GLAutoDrawable interface. |
| void removeGLEventListener(GLEventListener listener) | It removes GLEventListener to this drawable. |
GL2，GL3，GL4等OpenGL接口包含特定版本的所有核心方法。 GLProfile类的作用是根据所需版本指定特定的OpenGL接口。
| Method | Description |
|---|---|
| GLProfile get(String profile) | It is used to return an object of GLProfile. |
| boolean isGL3() | It is used to indicate whether profile is capable of GL2 or not. |
| boolean isGL3() | It is used to indicate whether profile is capable of GL3 or not. |
GLCapibilities类用于指定OpenGL的功能，例如OpenGL配置文件，颜色深度等。GLProfile类的对象作为参数传递给此类。
| Method | Description |
|---|---|
| GLProfilegetGLProfile() | It is used to return the required GLProfile. |
| booleanisStereo() | It is used to indicate whether stereo is enabled or disabled |
