Abstract:
1. A method comprising: computing, via a processor, visual smoothness values for each node in a wireframe mesh, each node comprising an indexed set of vertices in the wireframe mesh; partitioning the indexed set of vertices to produce a partitioned mesh having more nodes than the wireframe mesh; computing a visual smoothness for each node in the partitioned mesh; layering data describing the wireframe mesh into a plurality of layers by ordering nodes into a respective layer according to whether the nodes have a similar visual smoothness; and allocating first nodes associated with visible parts of the wireframe mesh to a first layer of the plurality of layers and allocating second nodes associated with non-visible parts to a second layer of the plurality of layers, wherein the second layer is only transmitted to a decoder where a user at the decoder is able to rotate the wireframe mesh to view the nodes associated with the non-visible parts, wherein average visual smoothness values associated with each of the plurality of layers reflect a respective layer's importance in the animation sequence; applying different parameters n, FR, Sp, and F applying unequal error protection to each respective layer of the plurality of layers according to a result of the channel bitrate algorithm.
