在Three.js中任意位置的特定轴上旋转对象-包括网格外部

如果要围绕世界空间中的任意线旋转对象，可以使用以下方法。该线由3D

point

axis

THREE.Object3D.prototype.rotateAroundWorldAxis = function() {    // rotate object around axis in world space (the axis passes through point)    // axis is assumed to be normalized    // assumes object does not have a rotated parent    var q = new THREE.Quaternion();    return function rotateAroundWorldAxis( point, axis, angle ) {        q.setFromAxisAngle( axis, angle );        this.applyQuaternion( q );        this.position.sub( point );        this.position.applyQuaternion( q );        this.position.add( point );        return this;    }}();
