Hello guys
I try to manipulate a .obj file and visualise a music throught it. I canno’t apply transformation of the obj with the function that I use. It work with a sphere but not with the obj. I maybe miss something realy easy 
.
My obj load function :
loader.load(
// resource URL
"./skullHead.obj",
// called when resource is loaded
function(object) {
var self = this;
object.scale.set(7, 7, 7);
object.position.set(0, 0, 0);
let man = object;
vmLoader.mesh = {};
const vmLoaderFunction = vmLoader;
man.traverse(function(child) {
//give color to the obj
if (child instanceof THREE.Mesh) {
child.material = new THREE.MeshPhongMaterial(pinkMat);
const geometry = new THREE.BufferGeometry();
const dataBuffer =
object.children[0].geometry.attributes.position;
geometry.setAttribute(
"position",
new THREE.BufferAttribute(dataBuffer, 3)
);
// let pos = geometry.attributes.position;
let pos = geometry.attributes.position.array;
console.log("pos", pos);
let vertex = new THREE.Vector3(
pos.getX(0),
pos.getY(0),
pos.getZ(0)
);
console.log("vertex", vertex);
console.log(vmLoaderFunction.mesh);
group.add(vmLoaderFunction.mesh);
},
// called when loading is in progresses
function(xhr) {
console.log((xhr.loaded / xhr.total) * 100 + "% loaded");
}
);
My audio change function :
function makeRoughBall(mesh, bassFr, treFr, item) {
console.log(item, mesh);
mesh.geometry.attributes.position.array.forEach(function(vertex, i) {
var offset = mesh.geometry.parameters.radius;
var amp = 7;
var time = window.performance.now();
vertex.normalize();
var rf = 0.00001;
var distance =
offset +
bassFr +
noise.noise3D(
vertex.x + time * rf * 7,
vertex.y + time * rf * 8,
vertex.z + time * rf * 9
) *
amp *
treFr;
vertex.multiplyScalar(distance);
});
mesh.geometry.verticesNeedUpdate = true;
mesh.geometry.normalsNeedUpdate = true;
mesh.geometry.computeVertexNormals();
mesh.geometry.computeFaceNormals();
}
