A computer-automated separation rules compliance method is disclosed. Separation rules that establish separation distance requirements between objects in a three-dimensional (3D) virtual environment are defined. Sample locations associated with at least some of the objects in the 3D virtual environment are specified. One or more of proximity and/or collision analysis is performed on the sample locations to determine separation distances between the objects. The determined separation distances are compared to the separation distance requirements. Objects in the 3D virtual environment that violate the separation rules based on said comparing are identified.

An image processing method and apparatus, an electronic device, and a computer-readable storage medium. The method includes: displaying, in a user interface, a picture obtained by observing a virtual environment from a virtual camera, the picture including a distant view portion corresponding to a virtual area of the virtual environment, the virtual area being outside a preset range associated with the virtual camera; detecting an editing operation performed on a virtual model in the virtual area; and updating, in response to determining the edited virtual model meets a specific condition, the distant view portion based on the edited virtual model.

An instruction (or set of instructions) that can be included in a program to perform a ray tracing acceleration data structure traversal, with individual execution threads in a group of execution threads executing the program performing a traversal operation for a respective ray in a corresponding group of rays such that the group of rays performing the traversal operation together. The instruction(s), when executed by the execution threads in respect of a node of the ray tracing acceleration data structure, cause one or more rays from the group of plural rays that are performing the traversal operation together to be tested for intersection with the one or more volumes associated with the node being tested. A result of the ray-volume intersection testing can then be returned for the traversal operation.

There is provided an instruction, or instructions, that can be included in a program to perform a ray tracing operation, with individual execution threads in a group of execution threads executing the program performing the ray tracing operation for a respective ray in a corresponding group of rays such that the group of rays performing the ray tracing operation together. The instruction(s), when executed by the execution threads will cause one or more rays from the group of plural rays to be tested for intersection with a set of primitives. A result of the ray-primitive intersection testing can then be returned for the traversal operation.

According to a method for virtual enhancement of a camera image, a camera image depicting an object is generated. A geometric description of a virtual auxiliary object as a surface in space and a pose of the auxiliary object with respect to the object are specified, wherein the auxiliary object separates part of the object from the rest of the object. An enhanced image is generated based on a superimposition of the camera image with a representation of the auxiliary object depending on the geometric description and the pose of the auxiliary object by a computing unit and displayed on a display device. The enhanced image is generated and displayed in such a way that the auxiliary object has a spatially variable transparency.

A ball tracking and scoring system and also enables a game implementation system using this system.

A processing method, rendering method and device for static components in a game scene are provided. The rendering method includes: a parent model corresponding to a plurality of static components is loaded, the parent model comprising at least two sub-models corresponding to at least two sub-components, and information of each of the at least two sub-models is recorded in a model file of the parent model; a scene global identifier of the at least one sub-model marked as hidden in the parent model is determined, wherein the scene global identifier includes identification information of each of the at least two sub-models in the game scene; and at least one sub-model not marked as hidden of the parent model is rendered in a preset manner.

In an example, a method includes acquiring, at a processor, a data model of an object to be generated in additive manufacturing, the data model comprising object model data representing a slice of the object model as a plurality of polygons and object property data comprising property data associated with the plurality of polygons. The slice may be inspected from a predetermined perspective at a plurality of discrete locations. It may be determined if each location is within a face of a polygon, and if so, the object property data associated with that polygon may be identified and associated with that location. The slice may further be inspected at a plurality of discrete locations along an edge of a polygon, the object property data associated with each location may be identified and associated with that location.

A computer-implemented method for clinical workspace simulation includes capturing a real-world environment by an imaging device of an augmented reality headset and generating a composite view by rendering a first virtual object relative to a surgical table in the real-world environment. Captured real-world environment and the rendered first virtual object are combined in the composite view, which is displayed on a display of the augmented reality headset worn by a user.

A method for generating a limitless path in a virtual reality environment (VR) for a continuous locomotion within a real physical space using Head-Mounted-Display (HMD) device associated with a user is provided. The method includes determining a line segment between two points that corresponds to an initial path travelled by the user. The method includes detecting a boundary of the VR environment to generate a next line segment. The method includes generating and adding a new line segment to end of the initial path. The method includes generating and adding the new line segment to the end of the next line segment. The method includes generating an updated path by adding the new line segment in a direction at the angle of shift angle to the direction of the next line segment. The method includes, configuring to output updated path as two-dimensional points to render updated path into VR environment.
