Consider a $3$D model represented as a triangle mesh $($given as $.$off file in the attachment$).$ Fix at least a

point on the $3$D model $($which will remain static while deformation$)$ and set target location for another

point on the surface which you want to move at the desired location. Now to deform the $3$D model,

implement the Laplacian deformation and the ARAP $($as$-$rigid$-$as$-$possible$)$ algorithms. Key functions

are given below.
