[Paraview] vtu file format

[Thierry Dubuis]

No, sorry I did't find any information about that.
There are information about XML part, binary datas must be encryted with 
Base64 algorithm and they could be compressed or not,
but no information about datas organization.

But perhaps must I ask this question to the VTK developpers group ?

Thanks again for your help,

Thierry Dubuis
