摘要： Systems and methods for implementing methods for cloud-based rendering of interactive augmented reality (AR) and/or virtual reality (VR) experiences. A client device may initiate execution of a content application on a server and provide information associated with the content application to the server. The client device may initialize, while awaiting a notification from the server, local systems associated with the content application and, upon receipt of the notification, provide, to the server, information associated with the local systems. Further, the client device may receive, from the server, data associated with the content application and render an AR/VR scene based on the received data. The data may be based, at least in part, on the information associated with the local system. The providing and receiving may be performed periodically, e.g., at a rate to sustain a comfortable viewing environment of the AR/VR scene by a user of the client device.

摘要： Systems and methods for providing an electrical waveform to a pi-cell polarization switch. The electrical waveform may reduce/limit ion accumulation in and/or light leakage associated with the polarization switch. The electrical waveform may include multiple segments, e.g., a first segment may drive the polarization switch to a first polarization state and may be defined by a first portion having a first voltage level and a first polarity and a second portion having the first voltage level and a second polarity opposite the first polarity and a second segment, occurring after the first segment, that may drive the polarization switch to the second polarization state. The second segment may be defined by a second voltage level having the first polarity. An absolute value of the first voltage level may be greater than an absolute value of the second voltage level.

摘要： Systems and methods for enhancing trackability of a passive stylus. A six degree of freedom (6DoF) location and orientation of a passive stylus may be tracked by a tracking system via a retroreflector system disposed on the passive stylus. Additionally, characteristic movements of one of a user's finger, hand, and/or wrist may be recognized by the tracking system. The passive stylus may useable to interact with a virtual 3D scene being displayed via a 3D display. A user input via the passive stylus may be determined based on the tracked 6DoF location and orientation of the passive stylus and/or the recognized characteristic movements. The retroreflector system may include multiple patterns of retroreflectors and one of the patterns may be a spiral pattern of retroreflectors disposed along a longitudinal axis of the passive stylus.

摘要： Systems and methods for replacing a 2D image with an equivalent 3D image within a web page. The 2D image displayed within a web page may be identified and a 3D image with substantially equivalent content may also be identified. The 3D image may be integrated into the web page as a replacement to the 2D image. Further, at least one user input manipulating the 3D image within the web page may be received. The at least one user input may include movement of a view point (or point of view) of a user relative to a display displaying the web page and/or detection of a beam projected from an end of a user input device (and/or an end of the user input device) intersecting with the 3D image.

摘要： Systems and methods for replacing a 2D image with an equivalent 3D image within a web page. Content of a 2D image displayed within a web page may be identified and 3D images may be identified as possible replacements of the 2D image. The 3D images may be ranked based on sets of ranking criteria. A 3D image with a highest-ranking value may be selected based on a ranking of the 3D images. The selected 3D image may be integrated into the web page, thereby replacing the 2D image with the selected 3D image. Further, a user input manipulating the 3D image within the web page may be received. The user input may include movement of a view point of a user relative to a display displaying the web page and/or detection of a beam projected from an end of a user input device intersecting with the 3D image.

摘要： Systems and methods for capturing a two dimensional (2D) image of a portion of a three dimensional (3D) scene may include a computer rendering a 3D scene on a display from a user's point of view (POV). A camera mode may be activated in response to user input and a POV of a camera may be determined. The POV of the camera may be specified by position and orientation of a user input device coupled to the computer, and may be independent of the user's POV. A 2D frame of the 3D scene based on the POV of the camera may be determined and the 2D image based on the 2D frame may be captured in response to user input. The 2D image may be stored locally or on a server of a network.

摘要： Systems and methods for displaying a stereoscopic three-dimensional (3D) webpage overlay. In some embodiments, user input may be received from a user input device and in response to determining that the user input device is not substantially concurrently interacting with the 3D content, interpret the user input based on a 2D mode of interaction. In addition, the user input may be interpreted based on a 3D mode of interaction in response to determining that the user input device is substantially concurrently interacting with the 3D content. The 2D mode of interaction corresponds to a first visual cursor, such as a mouse cursor, and the 3D mode of interaction corresponds to a second visual cursor, such as a virtual beam rendered to extend from a tip of the user input device.

摘要： Systems and methods for incorporating real world conditions into a three-dimensional (3D) graphics object are described herein. In some embodiments, images of a physical location of a user of a three-dimensional (3D) display system may be received from at least one camera and a data imagery map of the physical location may be determined based at least in part on the received images. The data imagery map may capture real world conditions associated with the physical location of the user. Instructions to render a 3D graphics object may be generated and the data imagery map may be incorporated into a virtual 3D scene comprising the 3D graphics object, thereby incorporating the real world conditions into virtual world imagery. In some embodiments, the data imagery may include a light map, a sparse light field, and/or a depth map of the physical location.
