Abstract: A plurality of vertices corresponding to a mesh of a current frame that is positionally tracked is divided into a plurality of vertex groups based on a predetermined constant integer. The plurality of vertex groups includes a first vertex group. A first position of a current vertex in the first vertex group is estimated based on a second position of a reference vertex in a reference frame that is different from the current frame. An estimation error indicating a difference between the reference vertex in the reference frame and the current vertex in the first vertex group is determined. A prediction mode of vertices in the first vertex group is encoded based at least on the estimation error between the reference vertex and the current vertex. Prediction information of the vertices in the first vertex group is generated based on the encoded prediction mode of the vertices of the first vertex group.
