Various methods and systems are provided for automatically classifying a plurality of image slices using body region bounding boxes identified from a localizer image. In one embodiment, a localizer image may be mapped to a plurality of bounding boxes, corresponding to a plurality of body regions, using a trained machine learning model. Coordinates of the plurality of bounding boxes may be used to determine body region boundaries, such that the body regions are non-intersecting and coherent. The body regions identified in the localizer image may then be correlated to image slice ranges, and image slices within each image slice range may be labeled as belonging to the corresponding body region.

A virtual reality system with an inspecting function of assembling and disassembling and an inspection method of assembling and disassembling based on virtual reality are presented. A learning-end acquires an inspection data and a teaching assembling-disassembling record being set with a plurality of checkpoints, plays the teaching assembling-disassembling record, modifies a learning assembling-disassembling status of a plurality of virtual objects based on user's operations for assembling or disassembling. The learning-end issues an assembling-disassembling error reminder when the learning assembling-disassembling status is inconsistent with a teaching assembling-disassembling status at any of the checkpoints.

The present invention relates to the technical field of two-dimensional (2D)/three-dimensional (3D) modeling, and in particular to a method, system, and device for combining models in a virtual scene, and a medium. The method of the present invention includes: placing a first model into a second model; determining a filling space and a removing space of the first model; filling an overlapping space between the first model and the second model with the second model, and filling the filling space of the first model with the second model; and removing the second model with which the removing space of the first model is filled, wherein when the overlapping space between the first model and the second model is filled with the second model, and the filling space of the first model is filled with the second model, the removing space of the first model is filled with the second model. The present invention simplifies a workflow of a scene designer, reduces repetitive work, and achieves a desired effect of the models.

A rhythm-based video game (“game”) is disclosed. In the game, a player slashes blocks representing musical beats using a pair of energy blades resembling a lightsaber. A gaming console renders multiple digital objects, e.g., digital blocks, digital mines and digital obstacles, that are approaching a player in a virtual space. The gaming console also renders a digital representation of an instrument, e.g., a lightsaber (“digital saber”), using which the player slashes, cuts or otherwise interacts with the digital blocks to cause a digital collision between the digital saber and the digital blocks. The player can score by slashing the digital blocks, not hitting the digital mines and avoiding the digital obstacles. The game presents the player with a stream of approaching digital objects in synchronization with music, e.g., a song's beats, being played in the game. The pace at which the digital blocks approach the player increases with the beats.

A graphics processing unit (GPU) includes one or more processor cores adapted to execute a software-implemented shader program, and one or more hardware-implemented ray tracing units (RTU) adapted to traverse an acceleration structure to calculate intersections of rays with bounding volumes and graphics primitives. The RTU implements traversal logic to traverse the acceleration structure, stack management, and other tasks to relieve burden on the shader, communicating intersections to the shader which then calculates whether the intersection hit a transparent or opaque portion of the object intersected. Thus, one or more processing cores within the GPU perform accelerated ray tracing by offloading aspects of processing to the RTU, which traverses the acceleration structure within which the 3D environment is represented.

Systems and methods for video presentation and analytics for live sporting events are disclosed. At least two cameras are used for tracking objects during a live sporting event and generate video feeds to a server processor. The server processor is operable to match the video feeds and create a 3D model of the world based on the video feeds from the at least two cameras. 2D graphics are created from different perspectives based on the 3D model. Statistical data and analytical data related to object movement are produced and displayed on the 2D graphics. The present invention also provides a standard file format for object movement in space over a timeline across multiple sports.

Disclosed is a system to obtain the data set including multiple variables. The system extracts the multiple variables from the data set. Based on the data set, the system creates an ontology indicating multiple relationships between two or more variables among the multiple variables, where a relationship among multiple relationships indicates a correlation between the two or more variables. The system obtains an intent associated with the user, and a visualization standard, where the visualization standard indicates an attribute associated with the visualization. The system generates a sequence of multiple visualizations to present to the user by ranking the multiple visualizations based on the correlation between the two or more variables, the visualization standard and the intent associated with the user. The system presents the sequence of multiple visualizations based on the ranking.

A method is disclosed, the method comprising the steps of receiving, from a first client application, first graphical data comprising a first node; receiving, from a second client application independent of the first client application, second graphical data comprising a second node; and generating a scenegraph, wherein the scenegraph describes a hierarchical relationship between the first node and the second node according to visual occlusion relative to a perspective from a display.

A system and method for coherency gathering for rays in a ray tracing system. The ray tracing system uses a hierarchical acceleration structure comprising a plurality of nodes including upper level nodes and lower level nodes. For each instance where one of the lower level nodes is a child of one of the upper level nodes, an instance transform is defined, specifying the relationship between a first coordinate system of the upper level node and the second coordinate system for that instance of the lower level node. The system provides an instance transform cache for storing a plurality of these instance transforms while conducting intersection testing.

An example computing system is configured to extract gridline information from a two-dimensional drawing file and determine, for the gridline information, first coordinate information that is based on a first datum. The computing system converts the first coordinate information into second coordinate information that is based on a second datum, where the second coordinate information is used by a three-dimensional drawing file. The computing system is also configured to receive a request to generate a two-dimensional view of the three-dimensional drawing file, where the two-dimensional view includes an intersection of two meshes within the three-dimensional drawing file. The computing device generates the two-dimensional view of the three-dimensional drawing file and adds, to the generated two-dimensional view, (i) at least one gridline corresponding to the gridline information and (ii) dimensioning information involving the at least one gridline and at least one of the two meshes.
