<font face="Droid Sans">Hello!<br>
Could you please help me with the following problem:<br>
<br>
For my purposes I need to store unchanged Unstructured Grid
across several time steps.<br>
At each time step the Scalars array for CellData is modified.<br>
I found out that if I can use the XDMF format in order not to
have to write the same Grid at each time step into new .vtk
file.<br>
<br>
But unfortunately it seems to be that in XDMF it is impossible
to use Lookup Tables to color the Scalars array in the proper
way to build the desired animation...<br>
Am I right or may be I missed this possibility?..<br>
<br>
I think also that I might try to use the manually specify color
lookup table in Paraview using "Interpret Values as Categories"
in Color Map Editor.<br>
It would be brilliant if it worked, but I </font><font
face="Droid Sans"><font face="Droid Sans">also </font>need to
specify the alpha (transparency) for colors of categories, which
seems to be unavailable feature...<br>
<br>
Could you please give me a hint on either 1) how to specify
Lookup Tables when using XDMF or 2) how to add transparency for
categorical colormaps in Paraview?<br>
<br>
Thanks in advance!<br>
<br>
