[Paraview] Highlighting specific nodes as a function of time

[Pradeep Jha]

Hello,

I have a NxNxN (N=512) cube data stored in multiple h5 format files for a
time varying solution. I read it in Paraview using a xmf file. I am able to
make a time varying movie of a particular iso-surface using the xmf file.

For each time step I have a particular node, say (x*, y*, z*), which I want
to highlight (using a sphere, for example). I have all these coordinates
stored in a another file. Can anyone please suggest me, how can I make a
movie where these particular nodes are highlighted along with the
iso-suface movie?

Thank you,
Pradeep

My present xmf file looks like this:

<?xml version="1.0" ?>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []>
<Xdmf Version="2.0">
  <Domain>
    <Grid Name="Box" GridType="Collection" CollectionType="Temporal">
    <Grid Name="mesh1" GridType="Uniform">
      <Topology TopologyType="3DCoRectMesh" Dimensions="512 512 512"/>
      <Geometry GeometryType="ORIGIN_DXDYDZ">

      </Geometry>
      <Time Value="00006" />
      <Attribute Name="vor" AttributeType="Scalar" Center="Node">
       <DataItem Dimensions="512 512 512" NumberType="Float" Precision="4"
Format="HDF">
        filename6.h5:/variable
       </DataItem>
      </Attribute>
    </Grid>
  ******many blocks like these************
    </Grid>
 </Domain>
</Xdmf>


And the points I want to highlight have coordinates like this:

 00000       241          54         310
 00006       241          54         308
 00012       240          55         310
 00018       239          55         310
 00024       261         294         395
 00030       256         373          32
 00036       257         372          32
 00042       257         371          32
 00048       258         370          32
 00054       258         369          32
