Abstract:
Systems and methods relate to receiving a plurality of video streams captured of a subject by a plurality of video cameras, each video stream including video frames time-synchronized according to a shared frame rate, each video camera having a known vantage point in a predetermined coordinate system; obtaining at least one three-dimensional (3D) mesh of the subject at the shared frame rate, the 3D mesh time-synchronized with the video frames of the video streams, the at least one mesh including a plurality of vertices with known locations in the predetermined coordinate system; calculating one or more lists of visible-vertices at the shared frame rate, each list including a subset of the plurality of vertices of the at least one 3D mesh of the subject, the subset being a function of the location of the known vantage point associated with at least one of the plurality of video cameras; generating one or more time-synchronized data streams at the shared frame rate, the one or more time-synchronized data streams including: one or more video streams encoding at least one of the plurality of video streams; and one or more geometric-data streams including the calculated one or more visible-vertices lists; and transmitting the one or more time-synchronized data streams to a receiver for rendering of a viewpoint-adaptive 3D persona of the subject.

Claim (Index 19):
A presenter server system comprising:\n a communication interface; a processor; and data storage containing instructions executable by the processor for causing the presenter server system to carry out a set of functions, wherein the set of functions includes:\n receiving, via the communication interface, a plurality of video streams captured of a subject by a plurality of video cameras, each video stream including video frames that are time-synchronized according to a shared frame rate, each video camera having a known vantage point in a predetermined coordinate system; \n obtaining at least one three-dimensional (3D) mesh of the subject at the shared frame rate, the 3D mesh time-synchronized with the video frames of the video streams, the at least one mesh including a plurality of vertices with known locations in the predetermined coordinate system; \n calculating, by the processor, one or more lists of visible-vertices at the shared frame rate, each list including a subset of the plurality of vertices of the at least one 3D mesh of the subject, the subset being a function of the location of the known vantage point associated with at least one of the plurality of video cameras; \n generating, by the processor, one or more time-synchronized data streams at the shared frame rate, the one or more time-synchronized data streams including:\n one or more video streams encoding at least one of the plurality of video streams; and \n one or more geometric-data streams including the calculated one or more visible-vertices lists; and \n \n transmitting, via the communications interface, the one or more time-synchronized data streams to a receiver for rendering of a viewpoint-adaptive 3D persona of the subject.
