Tetrahedron rotation by points

Questions
1

I am drawing a tetrahedron by coordinates. I have 4 vertex coord. I’m trying to get the right rotation from these points. I tried unsuccessfully with

const edge = points[0].distanceTo(points[2]);
const plane = new THREE.Plane();
const point = getPointInBetweenByLen(points[0], points[2], edge / 2);
plane.setFromCoplanarPoints(point, points[1], points[3]);
mesh.lookAt(plane.normal);

Hi!

What do you mean with this? Any explanatory picture of the desired result?

3

The vertices of the shape should be on points, these will be dynamic coordinates from xml, just like you helped me with the cone, only now there are 4 points

Is it not an option to build a tetrahedron, having these 4 points?
An example: Tetrahedron (non-indexed buffer geometry)

Thanks, you best. Maybe you have some resource where I can read more about BufferGeometry besides the official documentation?

As an option: Three.js Custom BufferGeometry
