DESIGNING A 3D MODELED OBJECT WITH 2D VIEWS

摘要

It is provided a computer-implemented method designing a three-dimensional modeled object, comprising the steps of providing (S10) a plurality of two-dimensional views of the modeled object, a three-dimensional wireframe graph, associating (S20), to each vertex of the wireframe graph, a local radial order between all the edges incident to the vertex, and then determining (S30) edge cycles, by browsing the wireframe graph following the local radial orders associated to the vertices. Such a method improves the design of a 3D modeled object.

1. A Computer-implemented method for designing a three-dimensional modeled object, comprising the steps of:
providing (S10) a plurality of two-dimensional views of the modeled object having curves and points defined thereon, a three-dimensional wireframe graph comprising edges that connect vertices, and correspondences between the edges and the vertices with respectively curves and points on the views; associating (S20), to each vertex of the wireframe graph, a local radial order between all the edges incident to the vertex, according to local partial radial orders between the curves corresponding to the edges on each of the views with respect to the point corresponding to the vertex; and then determining (S30) edge cycles, by browsing the wireframe graph following the local radial orders associated to the vertices.
