Question

我使用Trackballcontrol摄像机进行了俯视，后视，左视，右视，前视，后视。在切换到另一个视图之前，我先调用TrackBallControll重置方法，然后设置摄像机的新位置。它适用于除顶视图和后视图以外的所有视图。对于这最后两个视图，我无法再旋转相机。这是我的代码：

function changeView(type) {
controls.reset();
if (type === 'front') {
    camera.position.x = 0;
    camera.position.y = 0;
    camera.position.z = 500;
} else if (type == 'back') {
    camera.position.x = 0;
    camera.position.y = 0;
    camera.position.z = -500;
} else if (type == 'top') {
    camera.position.x = 0;
    camera.position.y = 500;
    camera.position.z = 0;
} else if (type == 'bottom') {
    camera.position.x = 0;
    camera.position.y = -500;
    camera.position.z = 0;
} else if (type == 'right') {
    camera.position.x = 500;
    camera.position.y = 0;
    camera.position.z = 0;
} else if (type == 'left') {
    camera.position.x = -500;
    camera.position.y = 0;
    camera.position.z = 0;
}
camera.lookAt(scene.position);

}

为什么会这样？

Threejs TrackBallControil顶视图和底视图不起作用
