Abstract: A computer-implemented method and system enables visualization of a computer-generated annotation on a real-world object in a real-world environment on a computerized system. The method and system creates a three-dimensional (3D) model of the real-world object, simultaneously displays the 3D model, the real-world object, and the real-world environment on a computer screen, and aligns the displayed 3D model and the displayed real-world object. The visibility of the 3D model is reduced and the 3D model is annotated in a real-world context. Reducing the visibility of the 3D model causes the annotation to appear on the displayed real-world object.

Abstract: A computer-implemented method for manipulating at least one three-dimensionally modeled object (O1) in a three-dimensional scene displayed on a computer display. The method displays, in the three-dimensional scene, a cursor (C) controlled by a pointing device (PD). The cursor has a shape representing three axes (X, Y, Z) of a coordinate system. Next the method selects an object of the three-dimensional scene; and detects a drag operation performed by a user using the pointing device. The drag operation translates the cursor and selects an axis of the coordinate system as a function of the translation of the cursor. Also the method performs a manipulation of the selected object. The manipulation depends on the selected axis and on a length (L) of the translation of the cursor (PP) along the selected axis.

Abstract: Described herein is a computer-implemented method for designing a three-dimensional modeled physical part. The method comprises providing a boundary representation of the modeled physical part, selecting, upon user action, a subset of the boundary representation that represents a geometric feature, identifying all the subsets of the boundary representation that are similar to the selected subset of the boundary representation by applying a feature similarity function.

Abstract: The invention notably relates to a computer-implemented method for compressing a three-dimensional modeled object. The method comprises providing a mesh of a three-dimensional modeled object, parameterizing (u,v) the mesh on a two-dimensional plane, converting the parameterized mesh into an image I, defining a grid of cells from the image I, each cell being defined by a set of control points, computing a relevance of each cell of the grid, determining at least one cell having a relevance lower than a pre-determined threshold, resizing the at least one determined cell and computing a resulting grid, computing a transformation for each pixel of the image from the resulting grid, and applying the computed transformation to the image I.

Abstract: The invention notably relates to a computer-implemented method for simulating a 3D scene. The simulation is carried out with a set of computing resources running in parallel. The method comprises partitioning a 3D scene into a plurality of zones. Each zone is sized to satisfy real-time computing constraint by one computing resource of the set. The method comprises assigning each zone of the plurality to a computing resource, computing an estimation of a load of each computing resource and determining whether one or more computing resources are over-loaded or under-loaded, computing, for each zone, a contribution of the zone to the load of the computing resource to which the zone is assigned, reassigning one or more zones of a computing resource that is over-loaded or under-loaded to another computing resource, the reassignment resulting from the computed contributions of the zones with a combinatorial optimization algorithm.

Abstract: The invention notably relates to a computer-implemented method for learning a function configured for reconstructing, for a class of real objects, a 3D modeled object that represents an instance of the class from a depth map of the instance. The method comprises providing a parametric model of the class, creating a database, and learning the function with the database. The method improves the 3D reconstruction of a real object from a depth map.

Abstract: A computer-implemented method and system create computer-generated three-dimensional (3D) models in a broken state (broken view representation). To create a 3D model in a broken state, an area of the 3D model in an unbroken state is removed to create the 3D model in the broken state and a mapping between the 3D model in the unbroken state and the 3D model in a broken state is implemented to enable operations performed on the 3D model in the broken state to utilize data defining the 3D model in the unbroken state. The mapping maintains a relationship between data defining the 3D model in the unbroken state and data defining the 3D model in the broken state.
