  • Patent number: 11967020
    Abstract: A distributed, cross reality system efficiently and accurately compares location information that includes image frames. Each of the frames may be represented as a numeric descriptor that enables identification of frames with similar content. The resolution of the descriptors may vary for different computing devices in the distributed system based on degree of ambiguity in image comparisons and/or computing resources for the device. A descriptor computed for a cloud-based component operating on maps of large areas that can result in ambiguous identification of multiple image frames may use high resolution descriptors. High resolution descriptors reduce computationally intensive disambiguation processing. A portable device, which is more likely to operate on smaller maps and less likely to have the computational resources to compute a high resolution descriptor, may use a lower resolution descriptor.

  • Patent number: 11961176
    Abstract: Disclosed approaches provide for interactions of secondary rays of light transport paths in a virtual environment to share lighting contributions when determining lighting conditions for a light transport path. Interactions may be shared based on similarities in characteristics (e.g., hit locations), which may define a region in which interactions may share lighting condition data. The region may correspond to a texel of a texture map and lighting contribution data for interactions may be accumulated to the texel spatially and/or temporally, then used to compute composite lighting contribution data that estimates radiance at an interaction. Approaches are also provided for reprojecting lighting contributions of interactions to pixels to share lighting contribution data from secondary bounces of light transport paths while avoiding potential over blurring.

  • Patent number: 11954809
    Abstract: The present disclosure relates to display systems and, more particularly, to augmented reality display systems. In one aspect, a method of fabricating an optical element includes providing a substrate having a first refractive index and transparent in the visible spectrum. The method additionally includes forming on the substrate periodically repeating polymer structures. The method further includes exposing the substrate to a metal precursor followed by an oxidizing precursor. Exposing the substrate is performed under a pressure and at a temperature such that an inorganic material comprising the metal of the metal precursor is incorporated into the periodically repeating polymer structures, thereby forming a pattern of periodically repeating optical structures configured to diffract visible light. The optical structures have a second refractive index greater than the first refractive index.

  • Patent number: 11941736
    Abstract: Systems and methods can enable the control the motion of an animated character based on imagery (e.g., captured by an image capture device such as a web camera or “webcam”) which shows a person in motion. Specifically, the animated character can be automatically rendered to have the same motion as the entity shown in the imagery (e.g., in real time). According to one aspect of the present disclosure, the animated character can be rendered by iteratively transforming (e.g., including deforming the actual geometry of) a vector-based surface illustration. Specifically, the systems and methods present disclosure can leverage the scalable and transformable nature of a vector-based surface illustration to provide more realistic motion-controlled animation, in which the underlying geometry of the animated character is able to be adjusted to imitate human motion more realistically (e.g., as opposed to basic rotations of fixed character geometry).
