This archive contains the data-sets and ParaView state files required to 
reproduce the examples provided on the TTK website (gallery and tutorials).

To run these examples, from the current directory, enter the following command
(omit the '$' character):
$ paraview --state=states/<example demo state file .pvsm>

See the TTK tutorial page for more details:
