ABSTRACT
Polygonal meshes are used in many application scenarios. Often the generated meshes are too complex not al-
lowing proper interaction, visualization or transmission through a network. To tackle this problem, simplification
methods can be used to generate less complex versions of those meshes.
For this purpose many methods have been proposed in the literature and it is of paramount importance that
each new method be compared with its predecessors, thus allowing quality assessment of the solution it provides.
This systematic evaluation of each new method requires tools which provide all the necessary features (ranging
from quality measures to visualization methods) to help users gain greater insight into the data.
This article presents the comparison of two simplification algorithms, NSA and QSlim, using PolyMeCo, a
tool which enhances the way users perform mesh analysis and comparison, by providing an environment where
several visualization options are available and can be used in a coordinated way.
Keywords: Polygonal Meshes, Quali
