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： Tracking objects presented within a stereo three-dimensional (3D) scene. The user control device may include one or more visually indicated points for at least one tracking sensor to track. The user control device may also include other position determining devices, for example, an accelerometer and/or gyroscope. Precise 3D coordinates of the stylus may be determined based on location information from the tracking sensor(s) and additional information from the other position determining devices. A stereo 3D scene may be updated to reflect the determined coordinates.

摘要： A voltage may be provided to a liquid crystal addressable element as part of a liquid crystal device. The provided voltage may be reduced from a driven state to a relaxed state in a time period greater than 1 μs. The reduction may further be performed in less than 20 ms. The liquid crystal device may be a polarization switch, which in some embodiments may be a multi-segment polarization switch. In one embodiment, pulses of limited duration of a light source may be provided to the polarization switch. The manner of voltage reduction may reduce optical bounce of the liquid crystal device and may allow one or more of the pulses of the light source to be shifted later in time.

摘要： Systems and methods for digitally drawing on virtual 3D object surfaces using a 3D display system. A 3D drawing mode may be enabled and a display screen of the system may correspond to a zero parallax plane of a 3D scene that may present a plurality of surfaces at non-zero parallax planes. User input may be received at a location on the display screen, and in response, a surface may be specified, rendered, and displayed at the zero parallax plane. Further, additional user input on the display screen may be received specifying drawing motion across the rendered and displayed surface. The drawing motion may start at the location and continue across a boundary between the surface and another contiguous surface. Accordingly, in response to the drawing motion crossing the boundary, the contiguous surface may be rendered and displayed at the zero parallax plane along with results of the drawing motion.

摘要： Presenting a view based on a virtual viewpoint in a three dimensional (3D) scene. The 3D scene may be presented by at least one display, which includes displaying at least one stereoscopic image of the 3D scene by the display(s). The 3D scene may be presented according to a first viewpoint. A virtual viewpoint may be determined within the 3D scene that is different than the first viewpoint. The view of the 3D scene may be presented on the display(s) according to the virtual viewpoint and/or the first view point. The presentation of the view of the 3D scene is performed concurrently with presenting the 3D scene.

摘要： System and method for controlling an imaging microscopy system (IMS). A control module may be coupled to an IMS configured to capture an image of a specified region of a specimen based on a specified perspective by controlling the specimen's position and/or orientation relative to an image capture subsystem of the IMS corresponding to the specified perspective. A 6 DOF tracker may detect position and/or orientation of a 6 DOF object with respect to a display of the IMS corresponding to a perspective for image capture of the specimen, and send indicative information thereof to the control module, which may determine the specified perspective based on the information, and may determine the specified region of the specimen for image capture based on the specified perspective. The control module may send information indicating the specified region and perspective to the IMS, thereby controlling capture of the image by the IMS.

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.
