Patent number: 10721491Abstract: The invention notably relates to a computer-implemented method for designing a 3D assembly of modeled objects. The method comprises rendering on a second computer a 3D assembly of modeled objects by merging a second 3D modeled object with at least one raster image of a first 3D modeled object, the at least one raster image having being streamed from a first computer to the second computer; sending from the second computer to the first computer first data related to the second 3D modeled object for contact computation between the first and second 3D modeled objects; and computing on the first computer a contact between the first and second 3D modeled objects.Type: GrantFiled: December 22, 2016Date of Patent: July 21, 2020Assignee: DASSAULT SYSTEMESInventors: Jean Julien Tuffreau, Malika Boulkenafed

Patent number: 10475161Abstract: The invention notably relates to a memory storage having a linear track and having recorded thereon a multi-resolution image system of an object, the multi-resolution image system including a set of images, each image representing the object and having a respective resolution, wherein the recording is according to a continuous injection from a space-filling curve of the set of images to the linear track, the space-filling curve interlaces the different images, and the intersection between the space-filling curve and each image is on a Hilbert curve. The invention improves the way to record a multi-resolution image system of an object on a memory storage.Type: GrantFiled: December 6, 2016Date of Patent: November 12, 2019Assignee: DASSAULT SYSTEMESInventors: Malika Boulkenafed, Jean-Julien Tuffreau

Patent number: 10410377Abstract: The invention notably relates to a computer-implemented method for compressing data representing values of a physical attribute in a predetermined space. The method comprises providing a signal that includes a mapping from leaf cells of a hierarchical subdivision of the predetermined space each onto a respective coefficient representative of a value of the physical attribute at the respective leaf cell. The method also comprises determining a discrete wavelet transform of the signal and encoding the determined discrete wavelet transform. The method provides an improved way to compress a modeled object that represents a real object.Type: GrantFiled: September 12, 2017Date of Patent: September 10, 2019Assignee: DASSAULT SYSTEMSInventors: Jean-Julien Tuffreau, Malika Boulkenafed

Patent number: 10275942Abstract: 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.Type: GrantFiled: December 9, 2016Date of Patent: April 30, 2019Assignee: Dassault SystemesInventor: Jean Julien Tuffreau
