Animation 设置三个.js顶点的动画

我正在尝试从collada模型中设置单个顶点的动画。 顶点只设置了一次动画，但之后不再设置动画

1：装上我的衣领

// name obj
var orgVerts = false;
var desVerts = false;
var material = new THREE.MeshBasicMaterial({ color:0x1e5679, wireframe:true });
var loader = new THREE.ColladaLoader();
var nameModel = false;

loader.options.convertUpAxis = true;
loader.load( '3d/name.dae', function ( collada ) {
    nameModel = collada.scene.children[0].children[0];
    nameModel.material = material;
    nameModel.geometry.dynamic = true;
    nameModel.position.set(0,0,0);//x,z,y- if you think in blender dimensions ;)
    nameModel.scale.x = .0035;
    nameModel.scale.y = .0035;
    nameModel.scale.z = .0035;
    scene.add(nameModel);
    orgVerts = nameModel.geometry.vertices; // make a backup of all verts
    genVerts(); // create a new array of random verts
});

2：在我的渲染函数中

var render = function () {
    requestAnimationFrame(render);
    // do stuff
    if(nameModel){
        if(window.globalCurrentSlide != 0){
            for(var r=0; r < nameModel.geometry.vertices.length; r++){
                var vert = desVerts[r]; // loop through all the destination verts
                nameModel.geometry.vertices[r].x = nameModel.geometry.vertices[r].x - (nameModel.geometry.vertices[r].x - vert.x)/20;
                nameModel.geometry.vertices[r].y = nameModel.geometry.vertices[r].y - (nameModel.geometry.vertices[r].y - vert.y)/20;
                nameModel.geometry.vertices[r].z = nameModel.geometry.vertices[r].z - (nameModel.geometry.vertices[r].z - vert.z)/20;
            }
        }else{
            for(var t=0; t < nameModel.geometry.vertices.length; t++){
                var vert2 = orgVerts[t]; // loop through all the original verts
                nameModel.geometry.vertices[t].x = nameModel.geometry.vertices[t].x - (nameModel.geometry.vertices[t].x - vert2.x)/20;
                nameModel.geometry.vertices[t].y = nameModel.geometry.vertices[t].y - (nameModel.geometry.vertices[t].y - vert2.y)/20;
                nameModel.geometry.vertices[t].z = nameModel.geometry.vertices[t].z - (nameModel.geometry.vertices[t].z - vert2.z)/20;
            }
        }
        nameModel.geometry.verticesNeedUpdate = true;
        nameModel.rotation.y += .005;
    }
    renderer.render( scene, camera );
}

var render=function（）{
请求动画帧（渲染）；
//做事
如果（名称模型）{
如果（window.globalCurrentSlide！=0）{
对于（var r=0；r

窗口。globalCurrentSlide

设置为0开始，一切正常。如果我将

window.globalcurrentsiled

更改为1，则所有顶点都会正确设置动画但是当我更改

窗口时。全局当前幻灯片

返回到0，顶点不会动画返回到其原始位置。我已经调试了堆，并且可以100%地说，

desVerts

和

orgVerts

都不会改变，它们是正确的。有什么想法吗？它快把我逼疯了

PS：我知道代码可以压缩，我只是在玩ATM。答案是我的

orgVerts

只是一个参考，而不是克隆。使用：

var geometry = nameModel.geometry.clone();
orgVerts = geometry.vertices;
