float fAspect=(float) width/height;
float fovy=60.0f;

gl.glViewport(0, 0, width, height);
gl.glMatrixMode(GL2.GL_PROJECTION);
gl.glLoadIdentity();

float top=(float) Math.tan(Math.toRadians(fovy*0.5))*NEAR_CLIP;
float bottom=-top;

/* draw */
public void display(GLAutoDrawable drawable) {
GL2 gl = drawable.getGL().getGL2();
scene.update();
scene.render(gl);
}

public void dispose(GLAutoDrawable drawable) {
}

我目前正试图在eclipse上运行JOGL，但是它发现了这部分代码的问题。它抛出的错误与getGL2（）有关，似乎可能缺少一个库，但我不确定哪一个。

这些是我用过的图书馆：

/usr/share/java/jogl.jar

/usr/share/java/jogl2.jar

/usr/share/java/gluegen-rt.jar

/usr/share/java/gluegen2-rt.jar

/usr/share/java/jogl-1.1.1+dak1.jar

/usr/share/java/jogl-all.jar

任何帮助都将不胜感激。

你将JOGL 1.1.1和JOGL 2混合在一起，这是完全错误的。请查看我们的wiki以选择正确的JAR： http://jogamp.org/wiki/index.php/Setting_up_a_JogAmp_project_in_your_favorite_IDE
