[vtkusers] Need help for understanding LOOKUP_TABLE.

Thu Jun 14 12:28:28 EDT 2007

Dear All,

I am confusing with the meaning of the LOOKUP_TABLE in legacy vtk format.

The following codes contain 4 streamlines and I want to color these with 

LOOKUP_TABLE my_table 4
0.0 1.0 0.0 1.0
0.0 0.0 1.0 1.0
1.0 0.0 0.0 1.0
1.0 1.0 1.0 1.0

I'd expecte the streamlines will result in green, blue, red and black in order under ParavView 2.6

but the result I got from Paraview is green, white, white, white streamlines. 

Can someone tell me what's wrong with the file?

And what is the meaning of "SCALARS" keyword?

Thank you.
