Techniques for rendering two-dimensional vector graphics are described. The techniques include using a central processing unit to generate tessellate triangles along a vector path in which each of the tessellate triangles is represented by a set of vertices. From the tessellate triangles, an index buffer and a compressed vertex buffer are generated. The index buffer includes a vertex index for each vertex of each of the tessellate triangles. The compressed vertex buffer includes a vertex buffer entry for each unique vertex that maps to one or more vertex indices of the index buffer. The index buffer and the compressed vertex buffer are provided to a graphics processing unit to render the vector path with anti-aliasing.

Systems and methods are disclosed for treating teeth to correct for malocclusions. This may be accomplished by applying a series of labels to a digital dental model and applying a rolling ball process to identify tooth boundaries separating one tooth from a neighboring tooth and to also determine the crown/gum margin. The user may further assign regions to the dental model to indicate hard regions and soft regions. With the dental model labeled and defined, the user may then generate a treatment plan for moving the labeled and defined tooth or teeth relative to one another to correct for any malocclusions. Upon approval of the treatment plan, a series of 3D printed dental appliances or aligners to be worn in series by the patient may be fabricated to ultimately move the tooth or teeth to a desired position.

Provided are an image processing apparatus and an image processing method that enable a strobe image using a 3D model to be generated. A strobe model in which 3D models of an object at a plurality of times generated from a plurality of viewpoint images captured from a plurality of viewpoints are disposed in a three-dimensional space is generated. When the strobe model is generated, a target object that is a target in which the 3D model is disposed in the strobe model is set according to a degree of object relevance indicating relevance with a key object serving as a reference for disposition of the 3D model in the strobe model.

A computer-implemented method is provided for visualizing multiple objects in a computerized visual environment. The method includes displaying to a user a virtual three-dimensional space via a viewing device worn by the user, and determining a data limit of the viewing device for object rendering. The method includes presenting an initial rendering of the objects within the virtual space, where the visualization data used for the initial rendering does not exceed the data limit of the viewing device. The method also includes tracking user attention relative to the objects as the user navigates through the virtual space and determining, based on the tracking of user attention, one or more select objects from the multiple objects to which the user is paying attention. The one or more select objects are located within a viewing range of the user.

Systems and methods and computer program products for processing three-dimensional (3D) graphics are provided. A method includes receiving 3D geometry data for a shape to be rendered to a display that comprises an array of hogels, the shape defined in a model space. The method can further include reducing downstream processing of the 3D geometry data to render the shape to the display, comprising identifying a subset of hogels in a hogel plane that have hogel bowtie frustums that intersect the shape.

A graphics rendering processor receives data related to a display and a user's gaze which is directed at the display. The user gaze may be detected based on inputs received from an optical sensor, such as a near-infrared sensor. The processor then renders different portions of the display based on the user gaze, such that an area where the user gaze is directed will receive higher rendering priority than an area at which the user gaze is not directed. In a processor with multiple cores which differ in precision, operation cost, etc. a controller may determine what portion of the display to render on which cores, based on the detected user gaze, content, or a combination thereof.

A cross reality system enables any of multiple devices to efficiently and accurately access previously persisted maps, even maps of very large environments, and render virtual content specified in relation to those maps. The cross reality system may quickly process a batch of images acquired with a portable device to determine whether there is sufficient consistency across the batch in the computed localization. Processing on at least one image from the batch may determine a rough localization of the device to the map. This rough localization result may be used in a refined localization process for the image for which it was generated. The rough localization result may also be selectively propagated to a refined localization process for other images in the batch, enabling rough localization processing to be skipped for the other images.

A multi-characteristic remeshing system that generates remeshed 3D graphical surfaces can include a compact geometric descriptive language (“CGDL”) conversion module, one or more geometric characteristic parsing modules, and a geometric computation module. The CGDL conversion module receives an input mesh for a 3D graphical object and CGDL source text that describes target characteristics of an output mesh of the 3D graphical object. Each geometric characteristic parsing module identifies inherent geometric characteristics of the input mesh, and generates a geometric characteristic map. The geometric characteristic map includes instructions to generate the output mesh with respective target characteristics. The instruction describes a relationship of the one or more inherent geometric characteristics with the respective target characteristic. The geometric computation module generates the output mesh with the target characteristics, based on the geometric characteristic maps from the geometric characteristic parsing modules.

A shadow rendering method for an image includes: re-projecting 3D coordinates of image pixels from an image space of the image to points on a 2D shadowmap space; estimating at least one of a horizontal and vertical distribution of the points in the shadow map space; for a flexible scale rasteriser ‘FSR’, updating a horizontal or vertical FSR curve corresponding to a distribution of FSR bins for the shadow map so that the corresponding horizontal or vertical distribution of points per bin is most even; and rendering the shadow map using flexible scale rasterization.
