I am getting points on a sphere:

function getPoints( event ) {

let a = this.geometry.vertices[event.face.a];

let b = this.geometry.vertices[event.face.b];

let c = this.geometry.vertices[event.face.c];

let point = {

```
x: ( a.x + b.x + c.x ) / 3,
y: ( a.y + b.y + c.y ) / 3,
z: ( a.z + b.z + c.z ) / 3
```

};

return point

}

but my sphere no longer shows a vertice for the InstancedGeometry I’m clicking on. It looks

As though the faces are there but the vertices are not. Is this intended? How do we add vertices back to geometry? Ive tried adding vertices back but they seem to be non distributed to the faces and all bunch up in one spot.

Any help?
