Code example for GL10

Methods: glFrustumfglLoadIdentityglMatrixModeglViewport

    public void onSurfaceChanged(GL10 gl, int w, int h) {
        mWidth = w;
        mHeight = h;
        gl.glViewport(0, 0, w, h);
        mProjector.setCurrentView(0, 0, w, h);
        * Set our projection matrix. This doesn't have to be done 
        * each time we draw, but usually a new projection needs to 
        * be set when the viewport is resized. 
        float ratio = (float) w / h;
        gl.glFrustumf(-ratio, ratio, -1, 1, 1, 10);
    private int mWidth;
    private int mHeight;
    private Context mContext;
