如何限制OrbitControl？ [英] How do I put limits on OrbitControl?

问题描述

是否可以对 OrbitControls.js 设置限制？想象一下，我要在地面上创建东西，我不希望相机放到地面下，知道我的意思吗？！放大和缩小也一样。有没有一种方法可以设置一些变量来限制该变量，因为我不想让相机靠近或太远？

Is there a way to put limits on the OrbitControls.js? Imagine I'm creating something above the ground, I wouldn't like the camera to go below the ground, know what I mean?! The same things goes for zoom in and zoom out. Is there a way to set some variables to limit that because I don't want the camera getting to close or too far away?

推荐答案

OrbitControls来源

放大/缩小

this.minDistance = 0;
this.maxDistance = Infinity;

停止旋转的位置：

this.minPolarAngle = 0; // radians
this.maxPolarAngle = Math.PI; // radians

不要跌倒地面

controls.maxPolarAngle = Math.PI/2;
