在Threejs中无法在任意轴上旋转对象

Question

我的平面几何具有以下坐标：

var planVertices = new Float32Array(18);
//Vertice 1
planVertices[0] = -47.63179171506315;
planVertices[1] = 33.77709642112255;
planVertices[2] = -39.992833485603335;
//Vertice4
planVertices[3] = -47.63719374716282;
planVertices[4] =33.67262125968933;
planVertices[5] = -39.885335769653324;
//Vertice2
planVertices[6] = -46.49726260129362;
planVertices[7] = 33.71843400657177;
planVertices[8] = -39.992833485603335;
//Vertice4
planVertices[9] = -47.63719374716282;
planVertices[10] = 33.67262125968933;
planVertices[11] = -39.885335769653324;
//Vertice3
planVertices[12] = -46.50266463339329;
planVertices[13] = 33.61395884513855;
planVertices[14] = -39.885335769653324;
//Vertice2
planVertices[15] = -46.49726260129362;
planVertices[16] = 33.71843400657177;
planVertices[17] = -39.992833485603335;                        
var geometry = new THREE.BufferGeometry();
geometry.addAttribute('position', new THREE.BufferAttribute(planVertices,3));
var material = new THREE.MeshBasicMaterial({
   color: 0x000000,
   side: THREE.DoubleSide,
});
var segments = new THREE.Mesh(geometry, material);
scene.add(segments);
var p1 = new THREE.Vector3(planVertices[0],planVertices[1],planVertices[2]);
var p2 = new THREE.Vector3(planVertices[6],planVertices[7],planVertices[8]);
var axisLocal = new THREE.Vector3().subVectors(p2,p1).normalize;
segments.rotateOnAxis(axisLocal,0.707);

如何从我的axisLocal向量旋转它？这只是我几何的一部分，我至少要有80个独立平面，要从其axisLocal旋转每个平面。

[已解决] 我将对象居中放置在原点中，然后进行旋转并重新应用逆向平移。

//Center object to the origin
var matTrans = new THREE.Matrix4();
var matTransInv = new THREE.Matrix4();
segments.geometry.computeBoundingBox();
var center = new THREE.Vector3();
segments.geometry.boundingBox.getCenter(center);
center.negate();
matTrans.makeTranslation(center.x, center.y, center.z);
matTransInv.getInverse(matTrans);
segments.applyMatrix(matTrans);
//Rotate object at the origin from its axis
var matRot = new THREE.Matrix4();
matRot.makeRotationAxis(axis, -0.707);
segments.applyMatrix(matRot);
//Inverse translation
segments.applyMatrix(matTransInv);

网格继承自Object3D，它具有.rotateOnAxis（axis，angle）方法。
