Abstract
A method and apparatus comprising computer code configured to cause a processor or processors to obtain a coded bitstream comprising a mesh sequence of a plurality of meshes of the 3D visual content and a displacement of a local coordinate system (LCS) or a global coordinate system (GCS) of at least one mesh of the plurality of meshes, the LCS or GCS being at a vertex of the at least one mesh, determine a projection coefficient of the displacement of the LCS or GCS, the projection coefficient indicating a unit tangent vector of the LCS or GCS in a normal direction to the vertex and is based on normalizing a tangent basis vector of the LCS or GCS, and decode the mesh sequence based on the projection coefficient of the displacement.
