Issues with BoxGeometry and normalize

Hi sorry for the noob question.
I would like to wiggle the vertices of a box. The problem is the normalised value aren’t the original position value of the box. I would like the vertices to go back to the original position after the wiggle effect ends.
You can see the issue here the red box is the original size. When the wiggle effect is at 0 the box is not the original size… I don’t know how to fix this… Can someone help ?

@Bretto

Reason behind issue is, you are using normal vector instead of position vectors to create wiggle effect.

Here is working fiddle, if you set ns = 0
box will be exact size of original box.

Thank you :wink:
