WitrynaImplicit surface models are popular since they can describe complex shapes with capabilities for surface and volume modeling and complex editing operations are easy to perform on such models. Moving least square (MLS) [3-6] and radial basis function (RBF) [7-15] are two popular 3D im-plicit surface reconstruction methods. http://www.orefind.com/blog/orefind_blog/2014/11/24/what-is-implicit-modelling-part-1
