[Paraview] [VTK] Grouping vtk objects to share attributes

[William Oquendo]

Dear all,

I have a simulation of complex bodies where a single complex body can be
though as formed by 2 planes and 4 spheres. For each of these objects I
have some data attributes to assign (let's say a vector force and a scalar
mass). I want to write a vtk (.vtp?) file to visualize (in Paraview) the
system, and to use the attributes to color/analyse the objects. Since each
object is composed of six primitives (2 planes and 4 spheres), in my
(naive) approach I will need to print the same data attributes to each of
these 6 primitives, which results into a 6x increases in data and
redundancy. I would like to know if there is a better way to print the
object data, like, for example, printing the data per object just once and
then sharing it to each of primitives of the object, or to group the
object's primitives into a group and then assigning the data to the group,
or something better.

Thanks in advance.

PS: I have already posted this question to the vtk list with no luck.
