在java中用openGL构建一个房间

Question

我正在尝试使用openGl构建一个房间，并将相机放入其中，但出于某种原因，当我尝试修改glu.gluLookAt（）时，它只是改变了观看的视角，而不是将相机放在房间。这是代码：

    public void display(GLAutoDrawable gLDrawable) {
    final GL2 gl = gLDrawable.getGL().getGL2();
    gl.glClear(GL2.GL_COLOR_BUFFER_BIT | GL2.GL_DEPTH_BUFFER_BIT);
    gl.glLoadIdentity();  // Reset The View
    gl.glTranslatef(0.0f, 0.0f, -5.0f);

    glu.gluLookAt( 0.1,0.1,-0.1,
                     0.5, 0.5, -0.5, 
                     0, 1, 0 );



    gl.glTexParameteri ( GL2.GL_TEXTURE_2D,GL2.GL_TEXTURE_WRAP_T, GL2.GL_REPEAT );
    gl.glTexParameteri( GL2.GL_TEXTURE_2D,GL2.GL_TEXTURE_WRAP_S, GL2.GL_REPEAT );

    gl.glBegin(GL2.GL_QUADS);
    // Front Face
    gl.glTexCoord2f(0.0f, 0.0f);
    gl.glVertex3f(-1.0f, -1.0f, 1.0f);
    gl.glTexCoord2f(2f, 0.0f);
    gl.glVertex3f(1.0f, -1.0f, 1.0f);
    gl.glTexCoord2f(2f, 1.0f);
    gl.glVertex3f(1.0f, 1.0f, 1.0f);
    gl.glTexCoord2f(0.0f, 1.0f);
    gl.glVertex3f(-1.0f, 1.0f, 1.0f);
    // Back Face
    gl.glTexCoord2f(1.0f, 0.0f);
    gl.glVertex3f(-1.0f, -1.0f, -1.0f);
    gl.glTexCoord2f(1.0f, 1.0f);
    gl.glVertex3f(-1.0f, 1.0f, -1.0f);
    gl.glTexCoord2f(0.0f, 1.0f);
    gl.glVertex3f(1.0f, 1.0f, -1.0f);
    gl.glTexCoord2f(0.0f, 0.0f);
    gl.glVertex3f(1.0f, -1.0f, -1.0f);
    // Top Face
    gl.glTexCoord2f(0.0f, 1.0f);
    gl.glVertex3f(-1.0f, 1.0f, -1.0f);
    gl.glTexCoord2f(0.0f, 0.0f);
    gl.glVertex3f(-1.0f, 1.0f, 1.0f);
    gl.glTexCoord2f(1.0f, 0.0f);
    gl.glVertex3f(1.0f, 1.0f, 1.0f);
    gl.glTexCoord2f(1.0f, 1.0f);
    gl.glVertex3f(1.0f, 1.0f, -1.0f);
    // Bottom Face
    gl.glTexCoord2f(1.0f, 1.0f);
    gl.glVertex3f(-1.0f, -1.0f, -1.0f);
    gl.glTexCoord2f(0.0f, 1.0f);
    gl.glVertex3f(1.0f, -1.0f, -1.0f);
    gl.glTexCoord2f(0.0f, 0.0f);
    gl.glVertex3f(1.0f, -1.0f, 1.0f);
    gl.glTexCoord2f(1.0f, 0.0f);
    gl.glVertex3f(-1.0f, -1.0f, 1.0f);
    // Right face
    gl.glTexCoord2f(1.0f, 0.0f);
    gl.glVertex3f(1.0f, -1.0f, -1.0f);
    gl.glTexCoord2f(1.0f, 1.0f);
    gl.glVertex3f(1.0f, 1.0f, -1.0f);
    gl.glTexCoord2f(0.0f, 1.0f);
    gl.glVertex3f(1.0f, 1.0f, 1.0f);
    gl.glTexCoord2f(0.0f, 0.0f);
    gl.glVertex3f(1.0f, -1.0f, 1.0f);
    // Left Face
    gl.glTexCoord2f(0.0f, 0.0f);
    gl.glVertex3f(-1.0f, -1.0f, -1.0f);
    gl.glTexCoord2f(1.0f, 0.0f);
    gl.glVertex3f(-1.0f, -1.0f, 1.0f);
    gl.glTexCoord2f(1.0f, 1.0f);
    gl.glVertex3f(-1.0f, 1.0f, 1.0f);
    gl.glTexCoord2f(0.0f, 1.0f);
    gl.glVertex3f(-1.0f, 1.0f, -1.0f);
    gl.glEnd();
