我一直试图在太阳系的openGL(使用JOGL)中实现3D动画到目前为止我有5个不同大小的行星,但我似乎有的问题是我无法在球体上添加地球纹理的地图可以任何人帮助我如何完成它？

这是我在Display方法中到目前为止的代码:

@Override
public void display(GLAutoDrawable drawable) {
    GL2 gl = drawable.getGL().getGL2(); 
    GLU glu = new GLU();
    gl.glClear(GL.GL_COLOR_BUFFER_BIT);

    //make sure we are in model_view mode
    gl.glMatrixMode(GL2.GL_MODELVIEW);
    gl.glLoadIdentity();
    glu.gluLookAt(10,20,20,0,3,0,0, 20, 0);
    //gl.glMatrixMode(GL2.GL_PROJECTION);
    //glu.gluPerspective(45,1,1,25);

    //render ground plane
    gl.glPushMatrix();
    gl.glTranslatef(-10.75f, 3.0f, -1.0f);
    gl.glColor3f(0.3f, 0.5f, 1f);
    GLUquadric earth = glu.gluNewQuadric();
    glu.gluQuadricDrawStyle(earth, GLU.GLU_FILL);
    glu.gluQuadricNormals(earth, GLU.GLU_FLAT);
    glu.gluQuadricOrientation(earth, GLU.GLU_OUTSIDE);
    final float radius = 3.378f;
    final int slices = 89;
    final int stacks = 16;
    glu.gluSphere(earth, radius, slices, stacks);
    glu.gluDeleteQuadric(earth);

    Texture earths;
    try {
      earths = TextureIO.newTexture(new File("earth.png"), …
