<p>Classification of 3D objects – the selection of a category in which each object belongs – is of great interest in the field of
machine learning. Numerous researchers use deep neural networks to address this problem, altering the network architecture and
representation of the 3D shape used as an input. To investigate the effectiveness of their approaches, we conduct an extensive survey
of existing methods and identify common ideas by which we categorize them into a taxonomy. Second, we evaluate 11 selected
classification networks on three 3D object datasets, extending the evaluation to a larger dataset on which most of the selected
approaches have not been tested yet. For this, we provide a framework for converting shapes from common 3D mesh formats into
formats native to each network, and for training and evaluating different classification approaches on this data. Despite being generally
unable to reach the accuracies reported in the original papers, we can compare the relative performance of the approaches as well as
their performance when changing datasets as the only variable to provide valuable insights into performance on different kinds of data.
We make our code available to simplify running training experiments with multiple neural networks with different prerequisites.
