Techniques applicable to a ray tracing hardware accelerator for traversing a hierarchical acceleration structure with reduced round-trip communications with a processor are disclosed. The reduction of round-trip communications with a processor during traversal is achieved by having a visibility mask that defines visibility states for regions within a geometric primitive available to be accessed in the ray tracing hardware accelerator when a ray intersection is detected for the geometric primitive.

A graphical user interface (GUI) is configured for displaying surfaces of simulated objects within a scene. The GUI comprises a selector to choose between displaying the scene as: a plurality of particles, wherein each particle comprises a plurality of attributes; a plurality of ellipsoids formed from the plurality of particles, wherein dimensions and orientation of each ellipsoid depend on the number and direction of neighboring ellipsoids within a search radius of the ellipsoid; or one or more splatted or rasterized surfaces formed from the plurality of ellipsoids. The GUI further includes a display window within which the GUI displays the scene.

There is provided an image processing apparatus and an image processing method that are capable of suppressing an increase in loads when a point cloud is generated from a mesh. Point cloud data is generated by positioning points at intersection points between a surface of a mesh and vectors each including, as a start origin, position coordinates corresponding to a specified resolution. For example, intersection determination is performed between the surface of the mesh and each of the vectors, and in a case where the surface and the vector are determined to intersect each other, the coordinates of the intersection point are calculated. The present disclosure can be applied to an image processing apparatus, electronic equipment, an image processing method, a program, or the like.

A method and apparatus for displaying road names and a storage medium, the method comprises: performing collision detecting on and loading planned road names according to planned road name data and priority levels of the planned road names included in a navigation route; and performing collision detecting on and loading annotations of other map contents except the navigation route in a navigation map. The method and apparatus for displaying road names and the storage medium are used to enable a user to view the planned road names of the navigation route on an overview page of the navigational route, thereby improving guidance of map display for navigation.

The system, method, and software in the presented invention converts manually drawn 2D projection pictures into their corresponding mathematically defined 2D or 3D model. The manually drawn model is drawn in a computer with a device such as mouse. A software executed in the computer then automatically finds junction points and curves between junction points and fits smoothed and mathematically defined curves between the junction points. Alternatively, junction points and the representative polynomials of the curves are mentioned manually by users. The 2D or 3D mathematical models are then reprojected by the said software to obtain the desired, more accurate, and smooth projections. The reprojection can be done from different viewing angles if needed, which avoids the hassle of redrawing the models.

In a graphics processing system comprising a graphics processor, a main memory, and a memory management unit, when rendering a frame that represents a view of a scene comprising one or more objects using a ray tracing process and the ray tracing process requires a traversal of a ray tracing acceleration data structure indicative of the distribution of geometry for the scene being rendered to determine geometry for the scene that may be intersected by a ray, at least part of the traversal of the ray tracing acceleration data structure is performed by the memory management unit (MMU).

An initial form of the garment may be manufactured using the fabrication data, and the measurement data used to obtain a three-dimensional model of the body region. The initial form of the garment may then be compared to the three-dimensional model; and the comparison used to modify the initial form of the garment.
