The old Threshold python interface looked like this:
someThresholdFilter.ThresholdRange = [5.0, 1000.0]

this now has to be:

someThresholdFilter.LowerThreshold = 5.0
someThresholdFilter.UpperThreshold = 1000.0

one also may need to set the used threshold method:

someThresholdFilter.ThresholdMethod = "Between" # default
someThresholdFilter.ThresholdMethod = "Above Upper Threshold"
someThresholdFilter.ThresholdMethod = "Below Lower Threshold"

@pierre-guillou
the following state files look broken:

• states/cinemaReader.pvsm
• states/nestedTrackingGraph.pvsm
• states/trackingFromOverlap.pvsm

thanks for having a quick look!
cheers

the example states/contourAroundPoint.pvsm is broken.
it currently looks like this:

while it should look like that:
https://topology-tool-kit.github.io/img/gallery/contourAroundPoint.jpg

this is a consequence of PR#40.

@kappe-c
this one is for you.
I suggest to roll back this state file to its previous version (I can roll back PR #40 if it's any easier for you) and only edit (with a text editor) the necessary part of the pvsm state file (see the following example: ba0daad)

Using the latest TTK (91d38a0522342af312ce11fea8118f76e5549d4b) and ParaView master (3aa1b5818b4b724cac09aaf62114011869d90706) the dragon state file gives an invalid result:

Changing the Upper/Lower Threshold in Pairs and PersitenceThreshold seems to fix the issue

There are no examples of how to use ttkSurfaceGeometrySmoother but there are multiple references suggesting that an example exists:

1. https://topology-tool-kit.github.io/examples/persistentGenerators_fertility/
2. https://topology-tool-kit.github.io/examples/persistentGenerators_casting/
3. https://topology-tool-kit.github.io/examples/persistentGenerators_skull/

All of the above examples mention ttkSurfaceGeometrySmoother but don't use the class at all. I would suggest removing the cross references or even better adding an example.

I'm able to run all examples except the nested tracking graph. Got a bunch of error messages "No proxy that matches: group=filters and proxy=MeshGraph were found... Could not create a proxy of group: filters type:MeshGraph"

While testing the ttk-data states with my ParaView 5.8.1, the following error occurred with nestedTrackingFromOverlap.py:

AttributeError: type object 'RenderView' has no attribute 'EnvironmentNorth'

Apart from nestedTrackingFromOverlap.py, the EnvironmentNorth attribute is also present in trackingFromOverlap.py which fails in the same manner. Both of these files were introduced in #62.

No error occurred when testing with ParaView 5.9.
Should the states be only compatible with the last ParaView version?
