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: It is provided a computer-implemented method for simulating the machining of a workpiece with a cutting tool having a cutting part and a non-cutting part. The method comprises providing a modeled volume representing the workpiece and a trajectory of the cutting tool; determining a colliding sweep of the cutting tool, wherein the colliding sweep represents the volume swept by the non-cutting front of the cutting tool when the cutting tool follows the trajectory; testing a collision with the workpiece according to the determining step. Such a method improves the simulation of the machining of a workpiece with a cutting tool.

Abstract: A computer-implemented method includes storing a plurality of scheduled elements in a memory area, displaying a time horizon via a display device, and displaying a first portion of the plurality of scheduled elements within the time horizon. In response to a user input, the time horizon is adjusted and a second portion of the plurality of scheduled elements is displayed within the adjusted time horizon.
Abstract: A computer tool generates user-defined diminished reality images of a subject environment from source images. The diminished reality images display less real-world objects in the subject environment than that displayed in the source images. A 3D model of the subject environment in diminished reality is formed from the diminished reality images. The 3D model supports augmented reality user interaction with views of the subject environment diminished in reality and tidied/decluttered of user-selected objects.
Abstract: In one embodiment, a computer method of verifying an operator is human includes automatically selecting a pattern and dividing the pattern into a plurality of textures. The method further includes projecting each texture onto a different respective displayed element in a 3D experience. The method additionally includes randomizing a position and/or an orientation of at least one displayed element of the different respective display elements in the 3D experience. The method also includes receiving operator manipulations of the randomized elements to solve for the pattern and make the pattern appear/reappear. The method further includes granting access to the operator if the pattern is made to appear/reappear. Access is granted upon determining that the operator has made the pattern is appear/reappear, and access is denied if the operator fails to make the pattern appear/reappear.
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 (?) of the significance image is extracted. A transformation T?, parameterized as an interpolating spline by a set of control points, is provided from ? to a resized spatial domain ??; subdividing ? 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 ? are deformed by displacing one or more control points of the cells having a lesser weighted average. The transformation T? over a spatial domain of the image I is computed using the displaced one or more control points.

Abstract: It is proposed a computer-implemented method for designing a staggered pattern of objects in a computer-aided design system, the method comprising the steps of: providing a reference object to be multi-instantiated; instantiating objects from the reference object for forming a grid with a number of rows and a number of columns, the grid being formed so that the rows are spaced from each other with a first distance in a first direction and each column being spaced from each other with a second distance in a second direction; shifting, in one of every two rows of the grid, the instantiated objects of all the columns of said one of every two rows of the grid with a third distance in the second direction.
