  • Publication number: 20200273354
    Abstract: A method of visibility event navigation includes receiving, via processing circuitry of a client device, a first visibility event packet from a server, the first visibility event packet including information representing 3D surface elements of an environmental model that are occluded from a first viewcell and not occluded from a second viewcell, the first and second viewcells representing spatial regions of a specified navigational route within a real environment modeled by the environmental model. The method also includes acquiring, surface information representing the visible surfaces of the real environment at a sensor and determining, a position in the real environment by matching the surface information to the visibility event packet information. The method further includes transmitting, the position from the client device to the server and receiving a second visibility event packet from the server if the at least one position is within the specified navigational route.

  • Patent number: 10469568
    Abstract: There is provided a method of predictive prefetching and transmitting from a server to a client device at least one partial visibility event packet and/or deferred visibility event packet including renderable graphics information occluded from a first viewcell and not occluded from a second viewcell, including otherwise renderable graphics information in a client view frustum not previously transmitted to the client device; determining an estimated maximal client view frustum; calculating a subset comprising renderable graphics information that is included in the estimated maximal client view frustum; determining whether the calculated subset has previously been transmitted to the client device by comparing the calculated subset to the stored renderable graphics information previously transmitted, and transmitting the at least one partial visibility event packet and/or deferred visibility event packet to the client device if said packet has not been previously transmitted to the client device.

  • Patent number: 9892546
    Abstract: A method of pursuit path camera model navigation includes, providing, via processing circuitry of one server, a future viewpoint located at a first location and a current viewpoint located at a second location and calculating a first prefetch region including one or more viewcells and one or more visibility even packets, the first prefetch region corresponding to the first location of the future viewpoint and the second location of the current viewpoint. The method further includes receiving commands to modify the first location of the future viewpoint to a third location at a first velocity, calculating a navigational intent of the future viewpoint based on the commands, and calculating a second prefetch region including the viewcells and the visibility event packets by collapsing the calculated first prefetch region into the second prefetch region, the second prefetch region corresponding to a predicted pursuit path based on the calculated navigational intent.

  • Patent number: 9852538
    Abstract: In an exemplary embodiment, a computer-implemented method determines a set of mesh polygons or fragments of the mesh polygons visible from a navigation cell. The method includes determining a composite view frustum containing predetermined view frusta and determining mesh polygons contained in the composite view frustum. The method includes determining at least one supporting polygon between the navigation cell and the contained mesh polygons. The method further includes constructing at least one wedge from the at least one supporting polygon, the at least one wedge extending away from the navigation cell beyond at least the contained mesh polygons. The method includes determining one or more intersections of the at least one wedge with the contained mesh polygons. The method also includes determining the set of the contained mesh polygons or fragments of the contained mesh polygons visible from the navigation cell using the determined one or more intersections.

  • Patent number: 9489762
    Abstract: In an exemplary embodiment, a method, conducted on a server, sends renderable graphics information to a client device, said graphics information including at least one set of graphics information visible from a second view region and not visible from a first view region. The method includes determining a likelihood that a viewpoint undergoes movement from said first view region to said second view region. The method further includes sending said at least one set of graphics information upon determination that the likelihood that the viewpoint undergoes movement from said first view region to said second view region is greater than a predetermined threshold, said movement determined according to a predetermined motion path.
