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

我從here下載JOGL 2.0，文件jogl-all.jar，跑從here採取一個簡單的代碼示例：JOGL 2.0不支持GLCanvas，Texture，Animator，但是jogl 1.0呢？

和我：

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

，還有一些人（從其他項目）：

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

我猜這個jar不支持這些類型，爲什麼？有什麼辦法呢？

這很奇怪，因爲2.0版本假設支持版本1.0支持的所有東西，或者我錯了嗎？此外，這段代碼與jogl 1.0很好地工作，但我必須使用2.0版本。

JOGL 1.1和2.0從javax.media.opengl變爲com.jogamp.opengl

對於兩種情況下JOGL項目的頂層包名稱列出的動畫類可以現在com.jogamp.opengl.util.Animator下找到與紋理現在是在封裝之間com.jogamp.opengl.util.texture.Texture

jogl的javadoc應該有助於找到你失蹤的其他課程。 https://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/
