Abstract: A computer-implemented method for switching from a first 3D view of a 3D scene to a second 3D view of the 3D scene including obtaining the first 3D view displayed from a plane of a locked viewpoint of the 3D scene, detecting a continuous user interaction including a slide a first and second location on the plane. The method further comprises computing a distance traveled by the slide, comparing the computed distance with a predetermined distance, and if the computed distance is greater than the predetermined distance, a switch from the first 3D view to the second 3D view is performed.

Abstract: A computer-implemented method for 3D reconstruction including obtaining 2D images and, for each 2D image, camera parameters which define a perspective projection. The 2D images all represent a same real object. The real object is fixed. The method also includes obtaining, for each 2D image, a smooth map. The smooth map has pixel values, and each pixel value represents a measurement of contour presence. The method also includes determining a 3D modeled object that represents the real object. The determining iteratively optimizes energy. The energy rewards, for each smooth map, projections of silhouette vertices of the 3D modeled object having pixel values representing a high measurement of contour presence. This forms an improved solution for 3D reconstruction.

Abstract: A computer-implemented method for sketch-processing. The method including obtaining one or more input sketches and determining one or more output sketches from the one or more input sketches. Each output sketch is closed and manifold. The determining of the one or more output sketches includes constructing a set of manifold sketches including each manifold input sketch. The constructing of the set of manifold sketches includes, for each respective non-manifold input sketch, determining two or more respective manifold sketches based on at least one intra-sketch intersection of the respective non-manifold input sketch. The determining of the one or more output sketches includes combining each pair of manifold sketches of the constructed set that share at least two intersections, to form one or more closed and manifold sketches. The method forms an improved solution for sketch-processing.

Abstract: The disclosure relates to a computer-implemented method for tessellation processing. The tessellation forms a surface representation of a real-world 3D object. The method comprises providing a constrained tetrahedral Delaunay mesh comprising the tessellation. The mesh is conformal and comprises one or more sets of tetrahedrons, each set representing a gap between portions of the tessellation, each gap having a size lower than a predefined threshold. The method further comprises determining a set of one or more tetrahedra faces of the mesh to be added to the tessellation, includes minimizing an objective function that includes a term penalizing surface creation by face addition to the tessellation. The minimization is under the constraint that a given set of tetrahedra faces of the Delaunay mesh is to be added to the tessellation. The given set of tetrahedra faces includes, for each gap of one or more gaps, the tetrahedra faces meshing the gap.

Abstract: Techniques including methods, apparatus and computer program products are disclosed. These techniques include computer instructions that are encoded on computer storage media for determining wettability. The techniques use a numerical aging computation process to provide a representation of a wettability alteration of a physical rock sample in the presence of at least two fluids is disclosed. The techniques include retrieving a representation of a physical rock sample, the representation including pore space and grain space data corresponding to the physical rock sample, calculating local curvature for each surface in the pore space, determining from the calculated local curvature whether water-film breakage will occur, and classifying the wettability of the physical rock based on the determination of water-film breakage.

Abstract: A computer-implemented method includes receiving, in computer memory, a first test data set that comprises results of a real-world test of a material, where the first test data set comprises a plurality of test data points. The method further includes identifying one or more critical points among the test data points in the first test data set and processing the first test data set with a computer processor to produce a second test data set with differing (e.g., fewer) test data points than the first test data set, wherein the second test data set includes all the test data points that were identified as critical points in the first test data set and at least some other data points.

The method includes obtaining a graph of operators executable by the query engine, the graph comprising a plurality of basic operators, at least two of said operators being of a first type each configured to find RDF triples of the RDF graph that match a respective basic graph pattern. The method further comprises identifying a group of operators among the at least two basic operators of the graph which are of the first type. The respective basic graph patterns of the group of operators have same subject and/or predicate and/or object and the identified group of operators is replaced in the graph by an equivalent operator configured to find RDF triples of the RDF graph that match the respective basic graph patterns of the group of operators.

Abstract: Embodiments assess ergonomic risk in environments, such as factories and workstations. One such embodiment begins by receiving process planning data for an operator performing a task. In turn, the received process planning data is used to generate a posture for the operator to perform the task in a certain real-world environment. The generated posture is processed using a hierarchical decision tree to determine ergonomic risk of the posture in the certain real-world environment. Output includes an indication of the determined ergonomic risk.
