GLCanvas序列化

Question

在我的应用程序中，我使用JOGL lib来处理OpenGL。

我需要序列化我的javax.media.opengl.awt.GLCanvas的实现。

import javax.media.opengl.*;
import javax.media.opengl.awt.GLCanvas;
import javax.media.opengl.glu.GLU;
import java.io.Serializable;

public class Canvas extends GLCanvas implements GLEventListener, Serializable {
private GLU glu;

private static final int FPS = 60;
private FPSAnimator animator;

public Canvas() {
    addGLEventListener(this);
}

@Override
public void init(GLAutoDrawable drawable) {
    drawable.setGL(new DebugGL2(drawable.getGL().getGL2()));

    glu = new GLU();

    animator = new FPSAnimator(this, FPS);
    animator.start();
}

@Override
public void display(GLAutoDrawable drawable) {
    if (!animator.isAnimating()) return;
    final GL2 gl = drawable.getGL().getGL2();

    gl.glClear(GL2.GL_COLOR_BUFFER_BIT | GL2.GL_DEPTH_BUFFER_BIT);

    setCamera(gl, glu, camera.getHeight(), camera.getOrigin());
}

@Override
public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) {
    final GL2 gl = drawable.getGL().getGL2();
    gl.glViewport(0, 0, width, height);
}

@Override
public void dispose(GLAutoDrawable drawable) {

}

private void setCamera(GL2 gl, GLU glu, float distance, Float origin) {
    gl.glMatrixMode(GL2.GL_PROJECTION);
    gl.glLoadIdentity();

    float widthHeightRatio = (float) getWidth() / (float) getHeight();
    glu.gluPerspective(45, widthHeightRatio, 1, 1000);
    glu.gluLookAt(origin.x, origin.y, distance, origin.x, origin.y, 0, 0, 1, 0);

    gl.glMatrixMode(GL2.GL_MODELVIEW);
    gl.glLoadIdentity();
}
}

我尝试写对象我的画布

   fout = new FileOutputStream("F:\\canvas.ser");
   oos = new ObjectOutputStream(fout);
   oos.writeObject(mCanvas);

但我有错误：

因此，GLCanvas中的字段不可序列化。我该怎么办？
