Abstract: In one embodiment, a system automatically generates a retrofit device based on a three-dimensional (3D) model of a legacy device. In operation, a physical design engine generates component instances based on legacy interface instances included in the legacy device. The physical design engine then generates an enclosure model that specifies an enclosure that houses the component instances. The physical design engine also generates computer code that is associated with a programmable instance as well as relatively simple assembly instructions for assembling a retrofit device that includes the enclosure, the legacy device, the component instances, and the programmable instance. Notably an user may configure an automated fabrication tool to generate the enclosure. Consequently, the system provides an automated design process for retrofitting legacy devices that does not rely on the user possessing any significant technical expertise.

Abstract: One embodiment of the invention disclosed herein provides techniques for transferring attributes from a source animated character to a target character. A character attribute transfer system identifies a first set of markers corresponding to the source animated character. The character attribute transfer system identifies a second set of markers corresponding to the target character. The character attribute transfer system generates a geometric correspondence between the source animated character and the target character based on the first set of markers and the second set of markers independent of differences in geometry between the source animated character and the target character. The character attribute transfer system transfers a first attribute from the source animated character to the target character based on the geometric correspondence.

Abstract: A simulation application receives simulation parameters associated with a simulation to be generated. The simulation parameters include geometry associated with the simulation and corresponding boundary conditions. The simulation engine processes the simulation parameters and then, using a neural network, generates a solution estimate. Based on the estimated solution, the simulation engine then executes a finite element analysis solver using the solution estimate as a starting point. The FEA solver iterates until a converged solution is reached. The converged solution is then provided to the end-user.

Abstract: A method, system, and apparatus provide the ability to control a system state of/in an image viewing application using a camera/portable viewing device. A screen of the camera is used to display a virtual reality view and an opening is positioned over a lens of the camera. The screen and physical buttons of the camera are not accessible when the camera is placed into the virtual reality viewing mechanism. An image is acquired from a camera through the opening. Color is used to make choices for operations. Alternatively, based on the toggling of the system state through a light blocking operation, a motion operation is conducted. The motion operation is based on length of time light is blocked and the length controls a speed of the motion operation.

Abstract: A system and method are disclosed for manipulating objects within a virtual environment using a software widget. The software widget includes one or more controls for performing surface constrained manipulation operations. A graphical representation of the software widget is superimposed over the object and enables a user to use simple mouse operations to perform the various manipulation operations. The position operation determines an intersection point between the mouse cursor and a surface of a different object and moves the object to the intersection point. The scale operation adjusts the size of the object. The rotate operation adjusts the rotation of the object around a normal vector on the surface of the different object. The twist operation deforms the object along a local z-axis. The orientation operation adjusts the orientation of the object with respect to the normal vector.

Abstract: A method, apparatus, system, and computer program product provide the ability to simulate a construction schedule. A first three-dimensional (3D) model and a schedule are acquired. The schedule includes activities for building the 3D model. Each of the activities is associated with model object(s) of the 3D model. A subset of the activities is selected based on properties of the activities. A first simulation appearance (of the model objects attached to the selected subset of activities) is defined. A second simulation appearance is defined for remaining/non-selected activities. The selected subset, the first simulation appearance, and the second simulation appearance are packaged into a playback profile that is capable of being applied to a second 3D model. A simulation of construction of the first 3D model (that is based on the playback profile) is played back.

Abstract: A method, apparatus, system, and computer program product provide the ability to search for and interact with three-dimensional (3D) objects in a 3D model/drawing. Searches may be conducted on a per object basis (based on properties of the object) and search queries may be amended based on shared/common attributes between objects found in an initial search. Differences in search results can be identified and the causality may be used to perform additional searches. Search results may be listed in a list view and a correspondence between objects in the list view and the modeling view may be visibly discernible. Further, selection of a single object from a search result may focus the view on such an object while removing any occluding objects. Multiple selected objects can be viewed in an array of rotationally synchronized viewports.

Abstract: In one embodiment, a dynamic effects subsystem automatically generates a dynamic effects animation. A graphical user interface enables an animator to sketch applied energies that influence graphical objects. Each applied energy includes flow particles that are associated with velocity fields. Over time, a dynamic effects engine moves the flow particles and the associated velocity fields along a overall direction associated with the applied energy. To generate each frame included in the dynamic effects animation, the dynamic effect engine computes samples of the graphical objects, computes the influences of the velocity fields on the samples, and updates the positions of the samples based on the influences of the velocity fields. Notably, the applied energies and the flow particles enable the animator to effectively and interactively control the automated animation operations of the dynamic effects engine.

Abstract: One embodiment of the invention is a pop-up engine that generates a pop-up card from a sliced 3D graphics model. In operation, a pop-up engine processes a sliced 3D model to identify locations where each slice of the 3D model is to attach to the pop-up card or to other slices of the 3D model. The pop-up engine traverses the boundary of each slice and, at intervals along the boundary, projects a ray toward the upper portion of the card. If the ray intersects a neighboring slice, then the slice attaches to the neighboring slice at that location. If, however, the ray does not intersect a neighboring slice, then the slice attaches to the upper portion of the card at that location. The pop-up engine then modifies the slice to include a hinge portion that connects the slice to either a neighboring slice or the upper portion at that location.
