Abstract:
1. A method for transmitting a 3D model synchronized with at least a first video frame of a 3D video representing stereoscopic content, the 3D model being provided for rendering along with the at least first video frame of the 3D video, wherein the 3D model includes one or more components and is comprised of a set of connected points in 3D space forming a polygonal mesh structure, the method comprising: generating a list of components of the 3D model, in which the components of the 3D model are ordered in accordance with their depth; based on the list of components, determining whether a component of the 3D model is completely hidden by other 3D content, wherein the other 3D content comprises at least one of the first video frame of the 3D video, another component of the 3D model, and another 3D model, wherein a component is an atomic part of the 3D model and can be individually transmitted for rendering purposes; transmitting those components of the 3D model that are not completely hidden by other 3D content; from remaining components of the 3D model, selecting one or more components of the 3D model that are not completely hidden by a next video frame of the 3D video or another component of the 3D model or another 3D model; and transmitting the selected components of the 3D model.
