### My Question

Hi I wanted to ask something about create and deform filled meshes (as tetra-mesh).
Currently I have this point cloud :
I would like to know if there is a way to have deform the tetramesh that I can get from this point cloud. I need to deform in a uniform manner the entire and not only the surface
Thank you in advance
