The data are cells from CFD FVM. I just found that the PV gui could export files which can then be loaded into meshlab; it implies that the problem should be related to my python script.
I report the gui way worked with both pv 3.8.1 and 3.10.1, both vrml and x3d formats. I am doing more study on my code. Thanks a lot for all your help.
