使用OpenGl和更新屏幕移动图像？

Question

我创建了一个OpenGl渲染器：

package com.jump.nuttyjump;

public class GlRenderer implements Renderer {
private Sprite square; // the square
private Context context;

public GlRenderer(Context context) {
    this.context = context;

    //Sprites
    this.square = new Sprite();
}

@Override
public void onDrawFrame(GL10 gl) {
    gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);
    gl.glLoadIdentity();

    // Draw all Sprites
    gl.glTranslatef(0.0f, 0.0f, -5.0f);
    square.draw(gl); // Draw the triangle
}

@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {
    if (height == 0) { // Prevent A Divide By Zero By
        height = 1; // Making Height Equal One
    }
    gl.glViewport(0, 0, width, height); // Reset The Current Viewport
    gl.glMatrixMode(GL10.GL_PROJECTION); // Select The Projection Matrix
    gl.glLoadIdentity(); // Reset The Projection Matrix
    // Calculate The Aspect Ratio Of The Window
    GLU.gluPerspective(gl, 45.0f, (float) width / (float) height, 0.1f,
            100.0f);
    gl.glMatrixMode(GL10.GL_MODELVIEW); // Select The Modelview Matrix
    gl.glLoadIdentity(); // Reset The Modelview Matrix
}

@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
    // Load Textures for all Sprites:
    square.loadGLTexture(gl, this.context);

    gl.glEnable(GL10.GL_TEXTURE_2D); // Enable Texture Mapping ( NEW )
    gl.glShadeModel(GL10.GL_SMOOTH); // Enable Smooth Shading
    gl.glClearColor(0.0f, 0.0f, 0.0f, 0.5f); // Black Background
    gl.glClearDepthf(1.0f); // Depth Buffer Setup
    gl.glEnable(GL10.GL_DEPTH_TEST); // Enables Depth Testing
    gl.glDepthFunc(GL10.GL_LEQUAL); // The Type Of Depth Testing To Do
    // Really Nice Perspective Calculations
    gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST);
}
}

现在，当我运行它时，它会显示我加载的图像。但是我不知道如何让它移动。

我将如何移动我加载的图像，然后“重新绘制”视图，就像使用画布一样？
