Boolean operations are used to create or modify models. These operations  in the majority of 3D object representations are very complex. In the last years a  significant trend in computer graphics has been the shift towards point sampled  3D models due to their advantages over other representations, such as simplicity  and efficiency. Two recent works present algorithms to perform interactive  boolean operations on point-based models: the work by Adams and Dutre? and  the work by Pauly et. Al.. Due to great importance of this novel representation  and of the use of boolean operations, the present work makes an introduction to  point-based representation, implements the algorithm proposed by Adams and  Dutre? with some improvements, and compares this implementation with the work  by Pauly et. al..
