I put an updated version of the instructions I wrote here: How to build VTK for Linux if you are a new user, hopefully other new users will find it easier to set up VTK by following these insteructions.
Yes I have read it, it will help a lot of new users. Your instructions are very clear and nice. Thanks very much.
So to answer your questions:
3. TK == Tkinter, yes. But I still don’t see why you will need it especially since Tcl has been removed from VTK.
4. Yes. Wheel is a special bundle format so it can be installed via pip install ./path/to/wheel. No additional feature in VTK, just a different output format which could also be a problem with what you are aiming to do.
Thanks Sebastien for the reply,
I am focusing on C++ examples now, Python perhaps later on.
