reset position if inside shape

hello,again,i have made this code,with a 3d model,the model starts dismorph after 100 frames.I have a box shape that is moved with mouse,i want when ever the vertices be inside the box,to reset their position to the original position,and reconstruct the model,while the others dismorph. Always resetting the position when they are in the box,and move when they are not.Can anyone help me.Until now what it happens,is that when the vertices are inside the box they stop moving.

Thanks in Advance
