Dmitri,

Please reply to the list rather than an individual so everyone can benefit
from the conversation.

Yes, that explanation is exactly what I thought you were talking about. See
this example for how to attach that temperature value to your grid points:

http://www.vtk.org/Wiki/Add_Miscellaneous_Data_to_Points_in_a_Polydata
http://www.vtk.org/Wiki/Add_Miscellaneous_Data_to_Cells_in_a_Polydata

I'm assuming the values are already in that type of array in your vtk file?
If you can't get it from here please provide the vtk file and we'll take a
look.

Thanks,

David
