We have previously published a multiresolution approach for the shape similarity comparison of polygon soup 3D models. The approach combined a single-resolution shape feature with a multiresolution representation produced by using the 3D alpha shapes algorithm of Edelsbrunner for the shape similarity comparison. The study evaluated the efficacy of the multiresolution shape comparison approach by using only one shape feature and only one database. This paper attempts a more comprehensive evaluation of the efficacy of the multiresolution approach by using four different single-resolution shape features and two different databases. Experiments showed that (1) the multiresolution approach does improve the performance of all the four shape features tested, and (2) the combination of the Surflet Pair Relation Histogram with the multiresolution approach performed the best among the tested.
