Abstract: A computer-implemented method is disclosed that includes automatically determining a ventilation grille opening size estimation for numerical simulation setup automation based on an input in a computer-implemented environment. The computer-implemented method includes creating screenshots of a plurality of computer-rendered images of a three-dimensional grille geometry, with the three-dimensional grille geometry disposed at a different angle of rotation about a first axis, identifying which, if any, of the screenshots has an image of the three-dimensional grille geometry with a total opening value that is larger than every other one of the screenshot three-dimensional grille geometry images, and designating the identified image as a target image for further processing to determine the ventilation grille opening size estimation.

Abstract: Disclosed are computer implemented techniques for correcting for numerically generated pressure waves at an inlet of a simulation space. The techniques include receiving a model of a simulation space and applying an inlet pressure to an inlet of the simulation space. The applied inlet pressure generates fluctuating velocities that produce undesired, numerically-generated pressure waves. The numerically generated pressure waves are measured to establish a measured pressure history. The measured pressure history is subtracted from the applied inlet boundary pressure history to provide a set of boundary conditions. The process conducts a fluid simulation using the set of boundary conditions. The process repeats using a subsequent set of boundary conditions, until an iteration is reached where the measured pressures near the inlet are sufficiently small to compensate for undesired, numerically-generated pressure waves, and thereafter stores that subsequent set of boundary conditions to provide a corrected set of boundary conditions.

Abstract: A computer-implemented method for 3D scanning of a real object with a camera having a 3D position including receiving, from the camera, an image of the real object, displaying on a screen, in an augmented reality view, the image of the real object enclosed within a virtual 3D box and, superimposed to the real object, a virtual structure made of a set of planar tiles, and being anchored to the virtual 3D box, each tile corresponding to a predetermined pose of the camera, detecting that a tile is pointed at with the camera; acquiring, from the camera, a frame of the virtual 3D box, thereby validating said tile, said frame being a projection of the virtual 3D box on the image, iterating for different 3D positions of the camera, until a sufficient number of tiles is validated for scanning the real object, and implementing a 3D reconstruction algorithm with all captured frames.

Abstract: A computer-implemented method includes receiving a digital representation of an image and generating CAD sketches from it. The number of surfaces in a CAD model depends upon the number entities at the sketch level. The method keeps the number of created sketch entities and constraints to a minimum. The method includes a scalable approach for a range of images. Each contour is represented by a sequence of points following a path corresponding to a boundary in the image. The method includes classifying each point in a particular one of the contours as a curve region or a corner region contour point, thereby segmenting the contour into plurality of curve regions separated by corner regions. The method includes optimally fitting a curve to each one of the curve regions to create the best possible representation of the curve region. Additionally, the refine algorithm automatically improves the fit wherever needed.

Abstract: A 3D modeled CAD object is flattened to a two dimensional 2D representation while maintaining a user selected wiring component represented in 3D. A user selected 3D component has a connector and a route segment with at least one stored sketch segment. A 3D and 2D tangent are calculated at a junction point of the route segment. A translation and rotation transformation is calculated to align the 2D and 3D tangents at the junction point. A calculated transformation matrix based on the translation and rotation transformation is used to display a flattened unconnected route segment aligned with the user selected 3D component.

Abstract: Embodiments calculate birefringence of materials. One such embodiment builds one or more three-dimensional structure models of one or more compounds forming a material. Each built three-dimensional structure model is aligned along a molecular axis and one or more tilt angles are set for each aligned three-dimensional structure model. A molecular polarizability tensor for each three-dimensional structure model with the set tilt angles is then calculated. An embodiment accounts for anisotropy by measuring the width and length of each model with the set tilt angles to determine aspect ratios. To continue, birefringence of the material is calculated based on the determined molecular polarizability tensors of the one or more models. Embodiments can be employed for simulating, optimizing, and designing real-world objects, e.g., in an optimization to select a material for a phone display that conforms with performance/manufacturing requirements.

Abstract: A computer-implemented method for generating a training dataset. The training dataset includes training patterns each including a 3D point cloud of a respective travelable environment. The generating method includes, for each 3D point cloud, obtaining a 3D surface representation of the respective travelable environment, determining a traveling path inside the respective travelable environment, and, generating a virtual scan of the respective travelable environment along the traveling path, thereby obtaining the 3D point cloud. Such a method forms an improved solution for generating a training dataset of 3D point clouds.
