Patent
Dassault Systemes | Date: 2015-04-10

The invention notably relates to a computer-implemented method for designing a three-dimensional modeled object that represents a physical entity. The method comprises providing sample points; determining a volumetric function, within a predetermined class of volumetric functions, as the optimum of an optimization program that explores orientation vectors defined at the sample points, wherein the optimization program penalizes a distance from the explored orientation vectors; and fitting the sample points with an isovalue surface of the volumetric function, wherein the program further penalizes oscillations of the fitted isovalue surface.

The invention notably relates to a method for designing a 3D modeled object. Provided is a modeling graph having nodes that represent geometrical objects and arcs that each represent a relationship, wherein procedural relationships are represented by unidirectional arcs, wherein the relationships linking the geometrical objects further include live relationships that are represented by bidirectional arcs, and wherein the provided modeling graph respects a criterion that all the arcs of each strong component of the modeling graph are bidirectional. Upon adding a relationship linking two of the geometrical objects that are included in the data defining the 3D modeled object before the addition, the method selects two geometrical objects to be linked by the relationship to be added, the selection being performed according to the criterion. Such a method improves the design of a 3D modeled object.

The invention notably relates to a computer-implemented method for designing a three-dimensional modeled object. The method comprises providing a modeling graph having nodes that represent geometrical objects and arcs that each represent a relationship linking the two geometrical objects represented by the incident nodes of the arc, wherein procedural relationships are represented by unidirectional arcs having the same orientation as the procedural relationships, and wherein the relationships linking the geometrical objects further include live relationships that are represented by bidirectional arcs. The method also comprises upon a modification of the data defining the 3D modeled object, determining a strong graph, wherein the strong graph is the graph of strong components of the modeling graph, and updating the 3D modeled object according to a traversal of the strong graph. Such a method improves the design of a 3D modeled object.
