[vtkusers] vtk file format

[Vincent MEYER]

Hi Immo,

Tanks for your answer, but the problem is that I have to use an unstructured 
grid as dataset and when I try to write the dataset attributes like you've 
showed me, an error message appears.
That is the type of vtk files I use. Have you got an idea how to add other 
scalar or vector attributes in the same file?

ASCII
DATASET UNSTRUCTURED_GRID
POINTS 77 float
0.000000 0.000000 0.000000
0.000000 0.003333 0.000000
....
CELLS 120 480
3 0 7 8
3 8 1 0
....
CELL_TYPES 120
5
5
....
CELL_DATA 120
SCALARS von_mises_stress float
LOOKUP_TABLE LookupTable1
61204.687064
40063.806155
....
POINT_DATA 77
VECTORS displacement float
0.000029 0.000022 0.000000
0.000030 0.000014 0.000000
........
Thanks

Vincent
