Discrete Differential Operators on Polygonal Meshes Fernando de Goes, Andrew Butts, Mathieu Desbrun April 2020 Geometry processing of surface meshes relies heavily on the discretization of differential operators such as gradient, Laplacian, and covariant derivative. While a variety of discrete operators over triangulated meshes have been developed and used for decades, a similar construction over polygonal meshes remains far less explored despite the prevalence of ... more Paper (PDF) |
