During the rendering of an image, specific pixels in the image are identified where antialiasing would be helpful. Antialiasing is then performed on these identified pixels, where anti-aliasing is a technique used to add greater realism to a digital image by smoothing jagged edges. This reduces a cost of performing antialiasing by reducing a number of pixels within an image on which antialiasing is performed.

Systems and methods for optimizing a model file include an occlusion reduction process. The occlusion reduction process includes acts of: (i) identifying points on a mesh section of a model, (ii) casting a set of rays toward the points, (iii) determining a number of rays that reach the points without being occluded by a portion of the model or a portion of another object, (iv) determining occlusion values for the points based on the number of rays that reach the points without being occluded; (v) determining whether the occlusion values for the points satisfy a predetermined occlusion threshold value; (vi) removing the mesh section from the model in response to determining that the occlusion values satisfy the predetermined occlusion threshold value, and (vii) refraining from removing the mesh section from the model in response to determining that the occlusion values fail to satisfy the predetermined occlusion threshold value.

The disclosure provides a mixed rendering system and a mixed rendering method. The mixed rendering system includes a client device configured to perform: determining at least one user-interactable object of a virtual environment; rendering the at least one user-interactable object; receiving a background scene frame of the virtual environment; blending the at least one rendered user-interactable object with the background scene frame as a visual content of the virtual environment; and providing the visual content of the virtual environment.

Aspects of the subject disclosure may include, for example, encoding a point cloud in a first frame of volumetric video in an octree format and identifying a first group of points of the point cloud, resulting in a first base layer including a base layer, a first enhancement layer and a second enhancement layer.

The prediction system comprises a plurality of predictor units arranged for receiving from a computer graphics application information on the virtual world and each arranged for obtaining a predicted set of subregions for rendering a virtual world using streamable objects, each predicted set being obtained by applying a different prediction scheme, a streaming manager arranged for receiving the predicted sets of subregions, for deriving from the predicted sets a working set of subregions to be used for rendering and for outputting, based on the working set of subregions, steering instructions concerning the set of subregions to be actually used.

Systems and techniques for processing and/or transmitting three-dimensional (3D) data are presented. A partitioning component receives captured 3D data associated with a 3D model of an interior environment and partitions the captured 3D data into at least one data chunk associated with at least a first level of detail and a second level of detail. A data component stores 3D data including at least the first level of detail and the second level of detail for the at least one data chunk. An output component transmits a portion of data from the at least one data chunk that is associated with the first level of detail or the second level of detail to a remote client device based on information associated with the first level of detail and the second level of detail.

The disclosure relates to a 3D reconstruction method based on an on-site edge-cloud collaboration for a cultivated land. An edge-cloud collaborative computing architecture is used, such that the edge computing device performs advance calculations after image data is acquired. The edge computing device measures performances of itself and a cloud data center, and arranges and deploys multiple 3D reconstruction containers in the cloud data center for the 3D reconstruction. Multiple reconstruction containers in the cloud data center perform reconstruction tasks in parallel to quickly obtain 3D reconstruction results, and provide them to the edge computing device for retrieval and download. This method is mainly oriented to agricultural project monitoring scenes, to reduce reconstruction time and a data transmission amount of 3D models, in order to improve a response speed and a quality of 3D reconstruction results, for large-scale on-site monitoring, acceptance, and review purposes of agricultural projects.

Systems and methods for generating an extended reality (XR) user interface are disclosed. A two-dimensional data set is imported. The two-dimensional data set defines a two-dimensional user interface design layout. The two-dimensional data set includes a transition data set corresponding to a user interface element included in the design layout. The two-dimensional data set is converted into a three-dimensional data set. The three-dimensional data set defines a three-dimensional user interface design layout corresponding to the two-dimensional design layout. The converting includes identifying three-dimensional art for each of a plurality of phases corresponding to the transition data set. An XR representation of the three-dimensional data set is provided for editing using an editing application associated with one or more XR devices. Based on the editing, the three-dimensional data set is exported as one or more files that are compatible with an XR development environment.

An image source (407) provides an image divided into segments of different sizes with only a subset of these comprising image data. A metadata generator (409) generates metadata structured in accordance with a tree data structure where each node is linked to a segment of the image. Each node is a branch node linking the parent node to child nodes linked to segments that are subdivisions of the parent node, or a leaf node which has no children. A leaf node is either an unused leaf node linked to a segment for which the first image comprises no image data or a used leaf node linked to a segment for which the first image comprises image data. The metadata indicates whether each node is a branch node, a used leaf node, or an unused leaf node. An image signal generator (405) generates an image signal comprising the image data of the first image and the metadata.
