[Paraview] name blocks or sets and export them in X3D files

[Pierre JUILLARD]

Dear Kristian,

I thank you for your answer.
I know understand a bit better how it works.

I was actually asking to guys of Web3D how should be managed a "mutli-part"
scene in X3D in this
thread<http://www.web3d.org/message_boards/viewtopic.php?f=7&t=2084>,
and I got the answer of using X3D <Switch> which I'm not sure is the correct
answer.

What you describe is interesting and I will have a deeper analysis of it.

Thanks for you help.
Best regards,


Pierre
