Greedy surface triangulation
WebNov 1, 2024 · This paper presents a greedy, region growing algorithm for anisotropic triangulation of geometry images obtained by geometric stretch parametrization. The algorithm compensates for the local stretch anisotropy and variations in the principal directions of the metric tensor by minimizing the total length of the new edges of triangles … WebThis paper proposes an algorithm GSG (Greedy Surface routing Greedy), for geographic routing in 3D environments. GSG firstly partitions whole network with 3D Restricted Delau-nay Triangulation. When a local-minimum is encountered because of a hole, a message is transferred on a surface with triangles in order to jump out of a local-minimum area.
