Getting the rotation of facet


Recommended Posts

Hey guys,

I'm thinking there's a really simple answer to this, but I'm currently blanking on it. Basically, I'm trying to position/rotate a cylinder such that it is perpendicular to a given facet. 

Here's the PG: https://www.babylonjs-playground.com/#U8ZVF8

It looks like it works for facets on part of the sphere (maybe?), but there's clearly something I'm missing.


Thanks in advance!

Something like this?


scene.onPointerMove = function(evt) {
       var pickResult = scene.pick(scene.pointerX, scene.pointerY);
        if (pickResult.hit) {
            var pickNormal = pickResult.getNormal();
            tracker.position = pickResult.pickedPoint;
            if(tracker.position.y > 0)
                tracker.rotation = BABYLON.Vector3.Up().add(pickNormal); 
            if(tracker.position.y < 0)    
                tracker.rotation = BABYLON.Vector3.Up().subtract(pickNormal);
