Abstract: Disclosed is a hybrid approach to rendering transparent or translucent objects, which combines object-space ray tracing with texture-space parametrization and integration. Transparent or translucent objects are first parameterized using two textures: (1) a texture that stores the surface normal at each location on the transparent or translucent object, and (2) a texture that stores the world space coordinates at each location on the transparent or translucent object. Ray tracing can then be used to streamline and unify the computation of light transport inside thick mediums, such as transparent or translucent objects, with the rest of the scene. For each valid (e.g., visible) location on the surface of a transparent or translucent object, the disclosed embodiments trace one or more rays through such objects and compute the resulting lighting in an order-independent fashion. The results are stored in a texture, which is then applied during the final lighting stage.

Abstract: Methods and systems for presenting an object on a screen of a head mounted display (HMD) include receiving an image of a real-world environment in proximity of a user wearing the HMD. The image is received from one or more forward facing cameras of the HMD and processed for rendering on a screen of the HMD by a processor within the HMD. A gaze direction of the user wearing the HMD, is detected using one or more gaze detecting cameras of the HMD that are directed toward one or each eye of the user. Images captured by the forward facing cameras are analyzed to identify an object captured in the real-world environment that is in line with the gaze direction of the user, wherein the image of the object is rendered at a first virtual distance that causes the object to appear out-of-focus when presented to the user. A signal is generated to adjust a zoom factor for lens of the one or more forward facing cameras so as to cause the object to be brought into focus.

Abstract: Systems and methods create and distribute addressable virtual content with interactivity. The virtual content may depict a live event and may be customized for each individual user based on dynamic characteristics (e.g., habits, preferences, etc.) of the user that are captured during user interaction with the virtual content. The virtual content is generated with low latency between the actual event and the live content that allows the user to interactively participate in actions related to the live event. The virtual content may represent a studio with multiple display screens that each show different live content (of the same or different live events), and may also include graphic displays that include related data such as statistics corresponding to the live event, athletes at the event, and so on. The content of the display screens and graphics may be automatically selected based on the dynamic characteristics of the user.
