I am using the raycaster to project a circle onto a geometry primitive (cone). The black circle is correctly cast onto the cone surface and rendered in yellow. Using the intersect object from the raycast, I have the intersected points on the cone and the unit normal of the intersected faces. From these I am attempting to draw the normal at 100 points along the curve on the cone. However, either I am rendering the normal lines incorrectly or the face normals from the intersect object are off. Any help or insight appreciated. Code segment of interest follows the snip.

var spline = new Array(); // stores pts for the curve

```
for (i = 0; i < thePoints.length; i++) { //thePoints holds all the pts on the black circle
var thispt = new THREE.Vector3(thePoints[i].x, thePoints[i].y, 120); // a point on the black circle
raycaster.set(thispt, new THREE.Vector3(0,0,-1)); // set up raycaster, use thispt as origin and 0,0,-1 as directional unit vector
var intersects = raycaster.intersectObject(scene.getObjectByName("mysurf")); // get intersect object
// console.log(intersects);
spline.push(intersects[0].point); // push the intersected pt to storage
// intersect object provides intersected pt and face normal
var ptOnCurve = intersects[0].point; // intersected pt
var faceNormal = intersects[0].face.normal.normalize(); // face normal
// draw the normal
var normalPts = [];
p1 = new THREE.Vector3(ptOnCurve.x, ptOnCurve.y, ptOnCurve.z).clone();
p2 = faceNormal.clone().multiplyScalar(10).add(p1);
normalPts.push(p1);
normalPts.push(p2);
var linematerial = new THREE.LineBasicMaterial({ color: 0x0000ff });
var linegeometry = new THREE.BufferGeometry().setFromPoints(normalPts);
var line = new THREE.Line(linegeometry, linematerial);
scene.add(line); // add the blue normal line to scene
```
