Green coordinates for triquad cages in 3d
WebWe introduce Green coordinates for triquad cages in 3D. Based on Green's third identity, Green coordinates allow defining the harmonic deformation of a 3D point inside a cage as a linear combination of its vertices and face normals. Using appropriate Neumann boundary conditions, the resulting deformations are quasi-conformal in 3D, and thus ...

WebNov 2, 2024 · The new position of a spatial point can be computed from its cage coordinates and the deformed cage. Previous works proposed several cage coordinates with different properties, including mean value coordinates (MVC) [7, 18], harmonic coordinates (HC) [5, 17], green coordinates (GC) , etc. For example, the computation … WebGreen Coordinates for Triquad Cages in 3D – Additional material JEAN-MARC THIERY, Adobe Research, France TAMY BOUBEKEUR, Adobe Research, France 7.1e-3 2.8e-1 3.1e-4 3.1e-1 1.8e-2 7.7e-2 3.9e-2 1.9e-1 Fig. 1. ... •Contrary to traditional Green coordinates, our coordinates do
