Three.js - Using Projector And Ray To Selected A Vertex

My overall aim is to be able to load an .obj file which is a human body. Allow the user to select two vertices and highlight them with flags. Then find the index of the two vertice

Solution 1:

To fix this I created a mesh from the object returned by the obj loader using this code

var loader = new THREE.OBJLoader();
            loader.load( "img/originalMeanModel.obj", function (object) {

              object.children[0].geometry.computeFaceNormals();
              var  geometry = object.children[0].geometry;
                      console.log(geometry);
              THREE.GeometryUtils.center(geometry);
              var material = new THREE.MeshLambertMaterial({color: 0xffffff, shading: THREE.FlatShading, vertexColors: THREE.VertexColors });
              mesh = new THREE.Mesh(geometry, material);
              model = mesh;
              // model = object;
               scene.add( model );
            } );

Then when performing the intersectObject I did it on the model not the scene

var intersects = ray.intersectObject(model);
