本文主要是介绍threejs两个向量旋转，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

threejs向量旋转

threejs一个向量绕另一个向量旋转

threejs向量变换

var v3 = new THREE.Vector3(0,1,1);
var v1 = new THREE.Vector3(1,0,0);
var v2 = new THREE.Vector3(1,1,0);
var v4 = new THREE.Vector3(0,0,1);
var angle1 = v1.angleTo(v2);  //
var angle2 = v2.angleTo(v1);  //

console.log(angle1);
console.log(angle2);


var v32 = v3.cross(v2);
console.log( v1.x + ' ' + v1.y + ' ' + v1.z );
console.log( v2.x + ' ' + v2.y + ' ' + v2.z );
console.log( v3.x + ' ' + v3.y + ' ' + v3.z );
console.log(v32);

var t1 = v1.normalize();
console.log(t1);

var t2 = v1.angleTo(v2);
console.log(t2);

var v12 = v1.cross(v4);
console.log(v12);
