Abstract  Curvature tells much about details of surfaces and is studied widely by researchers in the computer graphics community. In this paper, we first explain the mean-curvature view of Dirichlet energy of triangular surfaces and introduce a curvature representation of details, and then present surfaces editing applications based on their curvature representation. We apply our method to surfaces with complex boundaries and rich details. Results show the validity and robustness of our method and demonstrate curvature map can be a helpful surfaces detail representation.

Key words： Curvature      Detail representation      Mesh editing      Shape editing      Dirichlet energy
