Abstract: An embodiment provides a virtual reality experience by defining a model representing an object that includes experimental parameters. After defining the model, a model simulation is performed, using variations of the experimental parameters, that produces results for each of the one or more variations. The results include a value for a behavior of interest of the model for each of the variations. Next, the results are compressed to an interpolant comprising discrete polytope bins with continuous surrogates of the behavior of interest. Responsive to user provided values of the experimental parameters, a value of the behavior of interest is predicted using the interpolant. In turn, a virtual reality experience is provided by displaying to the user an effect on the model for the user-provided values of the one or more experimental parameters where the displayed effect on the model reflects the predicted value for the behavior of interest.

Abstract: A computer-implemented method and system automatically adjusts the size of a selection area to aid in a selection of an object generated by a computerized system. The method and system detect a series of movements of a pointer, where the pointer is utilized to select an entity of the object. The series of movements are small and continuous. A set of entities that occupies the selection area is determined and the entities are analyzed for an indication of a level of difficulty in selecting one of the entities. The size of the selection area is reduced when the indication implies that the level of difficulty will be decreased after reducing the size of the selection area.

Abstract: A computer-implemented method and system automatically adjusts the size of a rigid body model. The method and system construct a two-dimensional model or a three-dimensional model, where the model has one or more rigid bodies. The rigid bodies are converted into geometric primitives that represent a respective rigid body and enable the respective rigid body to resize. One or more of the primitives are constrained to one another. A solver process changes a size of at least one geometric primitive and a rigid body simulation process uses the resized primitive(s) as input.

Abstract: Embodiments provide methods and systems for modeling mechanical features of a structural dynamic system. A method according to an embodiment provides, in computer memory, a finite element model representing a structural dynamic system. Next, in a processor coupled to the computer memory, a system of equations with a first term representing a linear combination of a mass, a stiffness, and a damping of the finite element model and a second term representing modal damping is solved. According to such an embodiment, the system of equations is solved using the Sherman-Morrison-Woodbury formula or a preconditioned iterative method. In turn, an improved 3D model of a real world object based on the finite element model is formed utilizing results of the solved system of equations with the finite element model and modal damping to model mechanical features of the represented structural dynamic system.

Abstract: Techniques for aiding user input with a graphical user interface (GUI) are disclosed. A target object among various command regions of the GUI is predicted, e.g., substantially before the cursor reaches any of the regions. The command region corresponding to the predicted target object is enlarged to facilitate user selection of the predicted target object. Enlarging the predicted target object may cause the target object to overlap and/or occlude nearby command regions. After a first target object is predicted, the prediction may be changed based on updated cursor movements. By using predictive target enlargement, users are given early visual feedback about the target, and are given a larger target to acquire, thereby allowing them to be faster and less precise (their mouse direction can wander) yet still acquire their desired result.

Abstract: A computer-implemented method and system automatically manages relationships between moving parts of a computer-aided design model. Two parts are selected, the parts being structurally independent of one another. One of the parts is determined to be a driving part and the other part is determined to be a driven part. A new position is applied to the driving part, and temporary constraints between the driving part and the driven part are added. A constraint solver is executed to move the two parts into solved positions. Additionally, after execution of the constraint solver, the added temporary constraints are removed.

Abstract: A computer-implemented method for designing a 3D modeled object representing a real object comprises providing a 3D mesh representing the real object, a texturing image and a mapping between the vertices of the 3D mesh and pixels of the texturing image; then maximizing a probability P(L(V)) of the form: P ? ( L ? ( V ) ) = 1 Z ? exp ? ( - ? i = 1 n ? ? ? i ? ? ( L ? ( v i ) ) - ? f ? ? ? ? ? f ? ? ( { L ? ( v i ) } i ? f ) ) . Maximizing is performed with a predetermined discrete Markov Random Field optimization scheme viewing the 3D mesh and the pixel shifts associated to the texture coordinates of the vertices of the 3D mesh as a Markov Random Field of energy ?log(P(L(V)))?log(Z). The method then comprises texturing the 3D mesh according to the texturing image, to the mapping, and to the result of the maximizing. This provides an improved solution for designing a 3D modeled object a real object.

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 and system provide one or more primitive commands. Each primitive command when executed defines a shape of an object and accepts input data to specify one or more dimensions of the shape. When the dimensions are applied to the shape, a three-dimensional (3D) object that is a 3D part and/or a 3D feature is created. Input data is utilized by a selected primitive command to create a sketch as specified by a definition of the shape on a sketch plane that is automatically selected and to specify a transformation that creates the 3D object from the sketch.

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.
