Abstract: An improved algorithm and technique for use in interactive graphics is disclosed. The new algorithm works by keeping three values in fast, memoryless pixel local storage for coverage counting (store the current coverage count at the pixel being covered), original framebuffer color (stores the color that was in the framebuffer at the pixel being covered immediately before the current path starts rendering), and the path ID (stores the unique ID of the last path to be drawn at the current pixel). The framebuffer is accessed from a fourth, texture-backed, pixel local storage plane.

Abstract: Generating a three-dimensional virtual representation of a three-dimensional physical object can be based on capturing or receiving a capture bundle or a set of images. In some examples, generating the virtual representation of the physical object can be facilitated by user interfaces for identifying a physical object and capturing a set of images of the physical object. Generating the virtual representation can include previewing or modifying a set of images. In some examples, generating the virtual representation of the physical object can include generating a first representation of the physical object (e.g., a point cloud) and/or generating a second three-dimensional virtual representation of the physical object (e.g., a mesh reconstruction). In some examples, a visual indication of the progress of the image capture process and/or the generation of the virtual representation of the three-dimensional object can be displayed, such as in a capture user interface.

Abstract: Distributed real-time rendering is a cutting-edge solution to address the ever-increasing demands for realistic and immersive visual experiences, such as provided by augmented or artificial reality applications. Embodiments of the present specification provide a method and a system for distributed real-time rendering of a scene. The rendering is distributed among a root instance and a plurality of node instances. The root instance receives the scene to render, segments it into a plurality of objects, computes lighting parameters, assigns rendering tasks associated with objects to node instances, and communicates object metadata and the lighting parameters to the assigned node instance. The node instances render objects and create point clouds and u, v maps, which are then used by the root instance to render the scene for real-time display. The method and system can be used by end devices that include position sensors, processors, communication means and a display to provide immersive experiences.
