java - JOGL 2.0 不支持 GLCanvas ,Texture ,Animator ，但是 jogl 1.0 呢？

Question

我从 here 下载了 jogl 2.0 ，文件 jogl-all.jar ，并运行了一个取自 here 的简单代码示例:

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

import javax.media.opengl.GL;
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLCanvas;
import javax.media.opengl.GLCapabilities;
import javax.media.opengl.GLEventListener;
import javax.swing.JFrame;

import com.sun.opengl.util.Animator;

我得到了:

The import javax.media.opengl.GLCanvas cannot be resolved
The import com.sun.opengl cannot be resolved

还有一些(来自其他项目):

Texture cannot be resolved to a type
Animator cannot be resolved to a type

我猜 jar 不支持这些类型，这是为什么呢？有什么办法解决这个问题吗？

这很奇怪，因为 2.0 版假设支持 1.0 版支持的所有内容，或者我错了？

此外，此代码适用于 jogl 1.0，但我必须使用 2.0 版。

Answer 1

在 jogl 1.1 和 2.0 之间，jogl 项目的顶级包名称从 javax.media.opengl 更改为 com.jogamp.opengl

对于列出的两种情况，Animator 类现在可以在 com.jogamp.opengl.util.Animator 下找到，而 Texture 现在位于 com.jogamp.opengl.util 包中。纹理.纹理

jogl 的 javadoc 应该有助于找到您丢失的任何其他类。 https://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/
