... and now there has been a VTK 8.1.0 available since December. Since VTK6 is in such good shape, I am wondering if it would be useful to try to have multiple VTK versions co-installable in Debian (VTK6 6.3, VTK7 7.1.1, VTK8 8.1) or if we should head towards a Buster release with the single latest VTK and Python3 support.
I know it's been a while since I've looked into VTK, but I have some renewed interest and am making packages for VTK 8.1.0 for my own use. If I can help close this bug that would be good too. -Maitland
