如何对 OrbitControl 设置限制? [英] How do I put limits on OrbitControl?

问题描述

有没有办法限制OrbitControls.js?想象一下，我正在地上创造一些东西，我不希望相机进入地下，知道我的意思吗?！放大和缩小也是如此.有没有办法设置一些变量来限制它，因为我不希望相机太近或太远?

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 源

放大/缩小

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

在哪里停止旋转:

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

不要让到地下

controls.maxPolarAngle = Math.PI/2;
