Why? You will not see seams if you use exactly the same sets of 
coordinates, sharing them by DEF/USE, for all shapes. GPUs guarantee a 
proper pixel fill here, if all the shapes are under the same 
transformation, and rendered internally by the same method (e.g. all by 
OpenGL display lists, or none by OpenGL display lists, all by shaders or 
none by shaders).

Otherwise, the seams would be unavoidable, regardless if X3D has a 
special node for submeshes or not.
