Abstract: A computer-implemented method defines seams of a virtual garment or upholstery having a plurality of two-dimensional patterns (P) assembled by their edges (E0-E7). The method arranges said patterns around a three-dimensional avatar (AV). The position of each pattern depends on its situation within the assembled garment or upholstery. Next the method for each edge (E0) of each pattern, except edges previously identified as seamless or for which a seam has already been defined:b1) automatically identifies at least one edge (E1-E7), called candidate edge, which is suitable to be seamed to it;b2) if a plurality of candidate edges have been identified, selects one of them (E1) based on at least one geometric criterion; andb3) defines a seam between the edge and the selected, or the only, candidate edge.A computer program product, a non-volatile computer-readable data-storage medium and a Computer Aided Design system for carrying out such a method. Application of such a method to the manufacturing of a real garment or upholstery.

Abstract: Current real-time rendering techniques of virtual representations of jewelry with gemstones do not address the shimmer and sparkle of real gemstones. Embodiments of the present invention use real-time rendering methods and systems that enable flash scintillation and fiery scintillation on the facets of virtual representations of gemstones as they are manipulated online by the customer. A 3D representation of a gemstone is displayed. In response to user input corresponding to the manipulation of the displayed 3D representation of the gemstone, scintillations at facets of the 3D representation of the gemstone are determined. The scintillations are determined by loading a scintillation factor from a look-up table corresponding to an angle of incidence of a light source to a facet of the gemstone. The determined scintillations at the facets of the gemstone are displayed for the user in real-time.

Abstract: It is proposed a computer-implemented method for compressing a three-dimensional modeled object. The method comprises: providing a mesh of the three-dimensional modeled object; parameterizing (u,v) the mesh in a two-dimensional plane, the parameterization of the mesh resulting in a set of vertices having two-dimensional coordinates; providing a grid on the two-dimensional plane; and modifying the two-dimensional coordinates of each vertex by assigning one vertex to one intersection of the grid. Such compression method is lossless, completely reversible, suitable to efficiently reduce the storage size of a CAD file.

Abstract: A system and method updates Computer Aided Design (CAD) models. An augmented reality view of a subject asset is displayed. User interaction therewith causes a CAD model updater to search a CAD database for corresponding CAD model of the subject asset. The CAD model updater displays the CAD model view of the subject asset overlayed on the augmented reality view. With the mashed-up display of these two views, the CAD model updater enables user interaction therewith to update the corresponding CAD model. The updates to the CAD model are made to the CAD file of the model's originating CAD modeling application.

Abstract: The invention notably relates to computer-implemented method for resizing an image I. The method comprises the steps of: providing the image I to resize; and providing an image significance by computing a significance of each pixel in the image to resize. An original spatial domain (Ω) of the significance image is extracted. A transformation Tθ, parameterized as an interpolating spline by a set of control points, is provided from Ω to a resized spatial domain Ω′; subdividing Ω into cells, each cell being defined by a subset of control points of the set. For each cell, a weighted average of the significance of the pixels in the cell is computed, the weighted average being computed using the interpolating spline. The cells of Ω are deformed by displacing one or more control points of the cells having a lesser weighted average. The transformation Tθ over a spatial domain of the image I is computed using the displaced one or more control points. A resized image J is computed by applying the computed transformation Tθ to the spatial domain of the image I to resize.
