Explain the idea of Laplace Reconstruction / Laplace Editing!
The global shape of a mesh is encoded in its positions 
.
The local shape of a mesh is encoded in its Laplace vectors
.
Given all Laplace vectors of a mesh, we can reconstruct a global shape 
from the local shape:
We need to fix one intial vertex position
and solve for the remaining variables .
We can also use this as an editing metaphor by letting the user prescribe desired positions
for certain vertices 
. Incorporating this into the minimization formula gives
Additionally, we need to allow rotations of the detail vectors:
