volume vertex selection out of display list

Ok, I have a class that loads and renders .obj models.
A model are rendered through a display list.

Now my question :
Take e.g. that I define a cube that confines a couple of the vertices of one mesh (not all vertices !) Is there a way to select these vertices inside the box and do rotation on those only, and not to the entire mesh ???

Mail me if you have a solution to my problem…

Thank you,
