Title (EN) A METHOD FOR RECONSTRUCTING A 3D SURFACE FROM A 2D SKETCH
(FR) PROCÉDÉ DE RECONSTRUCTION D'UNE SURFACE 3D À PARTIR D'UNE ESQUISSE 2D
Abstract: front page image
(EN)The present invention relates to a method for reconstructing a three-dimensional surface in a domain wherein the three-dimensional surface is reconstructed from a two- dimensional sketch comprising at least one stroke with a vector field assigned to the at least one stroke. The method comprises the steps of: interpolating the vector field to form a dense vector field; and reconstructing the surface using the dense vector field; wherein interpolating the vector field comprises minimizing a non-linear functional of the vector field with a curl-free constraint on the dense vector field, the non-linear functional of the vector field involving terms defined over the domain and a term defined over the at least one stroke, and wherein the non-linear functional of the vector field is minimized using an augmented Lagrangian method.
(FR)La présente invention porte sur un procédé de reconstruction d'une surface tridimensionnelle dans un domaine dans lequel la surface tridimensionnelle est reconstruite à partir d'une esquisse bidimensionnelle comprenant au moins un segment avec un champ vectoriel affecté au ou aux segments. Le procédé comprend les étapes suivantes : l'interpolation du champ vectoriel pour former un champ vectoriel dense ; et la reconstruction de la surface à l'aide du champ vectoriel dense ; l'interpolation du champ vectoriel comprenant la réduction au minimum d'une fonction non linéaire du champ vectoriel avec une contrainte sans courbe sur le champ vectoriel dense, la fonction non linéaire du champ vectoriel mettant en jeu des termes définis sur le domaine et un terme défini sur le ou les segments, et la fonction non linéaire du champ vectoriel étant rendue minimale à l'aide d'une méthode lagrangienne augmentée.
