请确保在构建路径中添加 jogl 和 gluegen 库，以支持 `P3D`（OpenGL）渲染器。

以下是在 macOS 上的示例：使用与您的平台（操作系统和 CPU 架构）相对应的[jar 文件][1]。

[![在 Eclipse 项目中的 gluegen-rt 和 jogl jar 库位置][2]][2]

这些库文件应位于 Processing 安装文件夹中的 `Java/core/library` 内。

一旦您将相关的 jogl 和 gluegen-rt jar 文件添加到项目中，并将它们添加到构建路径中，您就应该能够无错误地进行编译。

Ensure you add the jogl and gluegen libraries to the build path as well for `P3D`(OpenGL) renderer support.

Here&#39;s an example on OSX: use the [jar files][1] specific to your platform (OS and CPU architecture)

[![gluegen-rt and jogl jar libraries location in in the eclipse project][2]][2]

They should be within the Processing install folder within `Java/core/library`.

Once you&#39;ve added the relevant jogl and gluegen-rt jar files to the project and added them to the Build Path you should be able to compile with no errors

以下是翻译好的内容：

在设置Processing应用程序时，您需要将要在size()函数中使用的渲染器类的名称传递进去。

在Processing IDE/环境中使用OpenGL时，您使用的是`"P3D"`，但是当您使用自定义IDE（例如Eclipse）时，您需要使用`PConstants.P3D`。这是一个字符串常量，其值为`"processing.opengl.PGraphicsOpenGL"` - 实际的OpenGL渲染器类的名称。

```java
public void settings() {
    size(W, H, processing.core.PConstants.P3D);
}
英文:

When you set up your Processing app you need to to pass in the name of the renderer class you want to use to the size() function.

In the Processing IDE/environment for OpenGL you use &quot;P3D&quot;, but when you use a custom IDE like Eclipse you need to use PConstants.P3D. That is a string constant which value is &quot;processing.opengl.PGraphicsOpenGL&quot; - the name of the actual OpenGL render class.

public void settings() {
	size(W, H, processing.core.PConstants.P3D);
}
