[Closed] MapVertices : extreme optimization or not ?

I have writed a function to weld the mapVertices of an object.
The function keeps only 1 mapVertice with the same coordinate for all the object.
For example : my object have 10×10 faces and all the faces are mapped with a “face mapping” (face by face). After the function was applied,there are only 4 mapVertices for the all faces:
[0,0,0]
[1,0,0]
[0,1,0]
[1,1,0]
(because the face mapping product only this kind of mapVertices)

Do you think that this object is correct (clean) ?

thanks
