How to prevent a mesh from shrinking too much when applying smoothing?
Error Control
Constrain the positions of the vertices such that they can only move by a certain extent from their original position.
-Balls
A vertex
must not move by more than
from its original position
.
If
leaves its
ball after a smoothing iteration, it is projected back onto the closest point inside the ball:

Error Slabs
The movement of a vertex
is constrained to its original tangent plane. Its position may not deviate from the tangent plane by more than
. If it does, it is projected back:
