Question

在以下代码中：

@Override
public boolean touchDragged(int p1, int p2, int p3)
{
    float x=p1;
    float y=Gdx.graphics.getHeight()-p2;
    float diff;
    float diff2;
    if(x>touchX){
        diff=(x-touchX)/2;
        cam.rotateAround(new Vector3(0f,0f,0f),new Vector3(0f,1f,0f),-diff);
    }
    if(x<touchX){
        diff=(touchX-x)/2;
        cam.rotateAround(new Vector3(0f,0f,0f),new Vector3(0f,1f,0f),diff);
    }
    if(y>touchY){
        diff2=(y-touchY)/2;
        cam.rotateAround(new Vector3(0f,0f,0f),new Vector3(1f,0f,0f),-diff2);
    }
    if(y<touchY){
        diff2=(touchY-y)/2;
        cam.rotateAround(new Vector3(0f,0f,0f),new Vector3(1f,0f,0f),diff2);
    }


    touchY=y;
    touchX=x;

    // TODO: Implement this method
    return true;
}

Note:TouchX and TouchY are the original touch down positions 相机将在指定的轴（0 1 0）或（1 0 0）上旋转。因此，如果我在x轴上旋转90度并开始在y轴上旋转，它似乎会旋转通过相机的视图，而不是在屏幕上按下手指。我知道为什么会发生这种情况（由于轴是预先指定的并且不会根据相机的变量而改变）但我想知道如何优化这一点以便相机将遵循触摸拖动

LibGDX 3d更好的相机操控
