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
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;
