given a quaternion, how to calculate the new vector of a three-dimensional vector rotated by this quaternion?
Quaternion refers to Quaternion of the threeJS document
I understand the formula for calculating rotation of quaternions. I can write it myself, but I always think that the quaternion of threejs must have an api that can be calculated. I don"t have to write it myself, but I can"t find it in the interface document. Which one is it?

if you want to calculate a dot ,:
1.
2.
3. 0:
4. :
in this way, a quaternion rotation operation is completed.
