Is zfp used in VTK?

(Orion Poplawski) #1

There is ThirdParty/zfp in the VTK source - but I can’t find any evidence that it is in use. Is there some planned future use or should it be removed?

Its (future) use is here: https://gitlab.kitware.com/vtk/vtk/merge_requests/2783

The original contribution came in with adding zfp and the compression filter. I did the third party import steps separately so that one MR didn’t have to deal with that process and adding the code. The contributor’s time ran out though, so I started to take it over and fixed a bunch of memory leaks. However, without tests or knowledge of how to test it, it has stalled out due to a lack of feedback.

So: feel free to disable it if you wish today.
