Assessment of mesh simplification algorithm quality

This paper describes a method to compare an original mesh and its simplified representation. Meshes considered here contain geometric features as well as other surface attributes such as material colors, texture, temperature, and radiation, etc. Many simplification algorithms have been presented in literature. In this paper we present a new method to assess mesh simplification algorithm quality according to the appearance attributes. This assessment allows the appreciation of local quality and the computation of global quality statistics of a simplified mesh. The method can be easily and quickly used. We present a fast algorithm to sample the surface of a triangular mesh. The sampling technique increases the assessment resolution and the statistic precision.
