Poly Line Source field Points broken in animation view
If I add a Line source, the following information is made available in the animation view:
- Point1 (0)
- Point1 (1)
- Point1 (2)
- Point2 (0)
- Point2 (1)
- Point2 (2)
- Resolution
- Visibility
- Opacity
All of these are scalar quantities. They work as expected, too.
If I add a Poly Line Source source (not sure why it has the Source again in the name), I get the following fields in the animation view:
- Closed
- Points
- Visibility
- Opacity
The fields Closed, Visibility, and Opacity again work as expected. But Points already looks odd when you add it: It shows up as "PolyLineSource - Points (-1)", with a default value of 0 (whatever that means). Sure enough, when I run the animation this way, ParaView 5.1.2 crashes.
I'd like to change the coordinates of certain points at certain keyframes, albeit not their number. Is that possible from within python at least?
PS: I'm not sure how to do anything with the animation view from within python because changes in it appear not to be traced.
PPS: The Expression field of the Python Annotation filter also appears to behave rather weirdly in the animation view (not entirely surprisingly, e.g. because interpolation of expressions would be weird -- only the step function approach could really be expected to work)
