unity rotate a list of points 3d code example

Example 1: rotate vector3 around pivot point unity

public Vector3 RotatePointAroundPivot(Vector3 point, Vector3 pivot, Vector3 angles) {    return Quaternion.Euler(angles) * (point - pivot) + pivot;  }

Example 2: unity rotate around point

transform.RotateAround(point, axis, degrees);
