In this paper we will present recent advances in geometry processing that are related to the Laplacian processing framework. This framework is based on linear operators defined on polygonal meshes, and furnishes a variety of processing applications, such as shape approximation and compact representation, mesh editing, filtering, watermarking and morphing. The core of the framework is the mesh Laplacian operator, which allows to define differential coordinates and new bases for efficient mesh geometry representation.10.2312/egst.2005104453-70
