Abstract: A computer-implemented method for rendering two overlapping textures in a 3D scene. The rendering method includes obtaining a first 3D support comprising a first rendered texture. The rendering method includes obtaining a second 3D support comprising a second rendered texture. The rendering method includes detecting that the second support intersects with the first support. The rendering method includes computing a third 3D support by merging the first 3D support and the second 3D support. The rendering method includes computing a third texture by mixing the first texture and the second texture. The rendering method includes rendering the computed third texture on the computed third 3D support. The rendering method includes displaying the rendered third texture on the third 3D support. The method forms an improved solution for rendering a 3D scene.

Abstract: A computer-implemented method for setting a typed parameter of a typed operation applied to a 3D modeled object in a 3D scene. The method comprises displaying a representation of the 3D modeled object in the 3D scene. The method comprises obtaining the typed operation to be applied on a point of interest of the displayed representation of the 3D modeled object and selecting a first typed parameter among at least two typed parameters, thereby defining the selected first typed parameter as a current selected typed parameter. The method comprises providing a 2D manipulator in the 3D scene for setting the current selected typed parameter and setting the current selected typed parameter upon user interaction with at least one logical area of the 2D manipulator associated with the current selected typed parameters. The method improves the setting of a typed parameter of a typed operation.

Abstract: A computer-implemented method for mapping a texture on one or more points in a 3D scene. The one or more points in the 3D scene are obtained from a user-input with an input device. The method includes determining, from the user-input performed with the input device, the one or more points in the 3D scene to be textured. The method includes computing a 3D support comprising the determined one or more points to be textured. The method includes computing a texture based on the determined one or more points. The method includes rendering the computed texture on the computed 3D support. The method forms an improved solution for rendering a 3D scene.

Abstract: A computer-implemented method for designing a three-dimensional (3D) mesh in a 3D scene. The method comprises displaying a 3D mesh in a 3D scene and providing a global orientation and selecting, with a pointing device, one or more vertices of the 3D mesh, thereby forming a set of one or more vertices. The method comprises computing at least one picking zone that surrounds each vertex of the set. The method comprises providing a first manipulator for controlling a displacement of each vertex of the set along one or more NUV directions and determining whether the pointing device is maintained within the picking zone. If not, the method comprises providing a second manipulator for controlling a displacement of the one or more vertices of the set along one or more directions defined by the global orientation. The method improves user interactions for switching back and forth a first and second manipulators.

Abstract: A computer-implemented method for applying, to a given curve, a CAD deformation operator. The given curve results from a conversion of a corresponding subdivision curve defined by a base mesh into a computer-aided design (CAD) curve format. The CAD deformation operator is configured to deform an input CAD object so as to create a contact geometrical relation with another CAD object. The method comprises converting the given curve into a format readable by the CAD deformation operator. The method further comprises applying the CAD deformation operator to the converted given curve. The method further comprises converting back the result of applying the CAD deformation operator into the CAD curve format.

Abstract: A computer-implemented method for converting a subdivision curve into a corresponding computer-aided design (CAD) curve format. The subdivision curve is controlled by a base mesh. The base mesh is formed by vertices connected by one or more edges. The subdivision curve defines at least a part of a product to be manufactured for designing the product. The method comprises transforming the subdivision curve into a G2-continous CAD curve. The CAD curve is formed by the union of one or more Bezier curves. Each Bezier curve corresponds to a respective edge of the base mesh. A control polygon of the CAD curve is computed from the base mesh. The transformation is based on a Catmull-Clark refinement process.

Abstract: A computer implemented method for designing a 3D modeled object representing a manufacturing product. The method includes obtaining a base mesh representing the 3D modeled object, selecting one or more connected edges of the base mesh, subdividing the base mesh based on the selected edges by obtaining a bevel pattern area over the selected path. The method obtains, for at least one of the two endpoints of the path, a transition area by grouping all faces sharing the at least one of the two endpoints of the path, except those of the computed bevel pattern area. The method re-meshes the transition area by obtaining a transition vertex located in the transition area and computing an edge connecting each vertex of the pair of vertices with the obtained transition vertex. The method outputs the subdivided base mesh. This improves the design of a 3D modeled object.
