Abstract: Methods, systems, devices and computer software/program code products enable efficient handling and remedying of unreliable sensor data, such as data captured by cameras in a virtual 3-dimensional (V3D) imaging or communications system; and enable, in a visual communications system involving a plurality of display devices usable by respective users, synchronization to a common space, and display of images by a receiving device in an orientation independent of the angle at which the receiving device is held.

Abstract: In some aspects, systems and methods provide for forming groupings of a plurality of independently-specified computation workloads, such as graphics processing workloads, and in a specific example, ray tracing workloads. The workloads include a scheduling key, which is one basis on which the groupings can be formed. Workloads grouped together can all execute from the same source of instructions, on one or more different private data elements. Such workloads can recursively instantiate other workloads that reference the same private data elements. In some examples, the scheduling key can be used to identify a data element to be used by all the workloads of a grouping. Memory conflicts to private data elements are handled through scheduling of non-conflicted workloads or specific instructions and/or deferring conflicted workloads instead of locking memory locations.

Abstract: A user interface to a virtual camera for a 3-D rendering application provides various features. A rendering engine can continuously refine the image being displayed through the virtual camera, and the user interface can contain an element for indicating capture of the image as currently displayed, which causes saving of the currently displayed image. Autofocus (AF) and autoexposure (AE) reticles can allow selection of objects in a 3-D scene, from which an image will be rendered, for each of AE and AF. A focal distance can be determined by identifying a 3-D object visible at a pixel overlapped by the AF reticle, and a current viewpoint. The AF reticle can be hidden in response to a depth of field selector being set to infinite depth of field. The AF and AE reticles can be linked and unlinked, allowing different 3-D objects for each of AF and AE.

Abstract: Methods, systems and computer program products (“software”) for rendering scene content in a form configured for visually improved presentation on at least one holographic display device comprise: (A) recognizing at least one meaningful element within the scene content; (B) selecting, from the at least one recognized meaningful element, at least one selected meaningful scene element; (C) determining, based at least in part on the at least one selected meaningful scene element, at least one scene transform; and (D) utilizing the at least one determined scene transform, rendering multiple 2-dimensional perspectives of the content, the multiple 2-dimensional perspectives being configured for visually improved presentation on at least one holographic display device.

Abstract: Communication methods, systems and computer program products (“software”) (1) facilitate virtual immersion of one or more remote viewing participants into a captured scene which may include any number of physically present participants, and (2) provide indications of the remote viewing participants that can be seen or discerned by the physically present participants.

Abstract: Systems and methods for producing an acceleration structure provide for subdividing a 3-D scene into a plurality of volumetric portions, which have different sizes, each being addressable using a multipart address indicating a location and a relative size of each volumetric portion. A stream of primitives is processed by characterizing each according to one or more criteria, selecting a relative size of volumetric portions for use in bounding the primitive, and finding a set of volumetric portions of that relative size which bound the primitive. A primitive ID is stored in each location of a cache associated with each volumetric portion of the set of volumetric portions. A cache location is selected for eviction, responsive to each cache eviction decision made during the processing. An element of an acceleration structure according to the contents of the evicted cache location is generated, responsive to the evicted cache location.

Abstract: Methods, devices, systems and computer software/program code products improve the reliability of scene reconstruction through the use of a persistent store or cache to retain scene information observed across one or more previous frames.
