[Tkinter-discuss] Canvas performance, OpenGL, VTK

[Beinan Li]

Hi tkinter,

I'm investigating into tkinter for data visualization with Python.
Seems that the Canvas widget is the one for drawing data curves,
and I will need several Canvas at the same time for different views
and the same data.

Now the question is how is the general graphics performance if I
need to update the Canvas frequently, e.g., 30-60fps?

If the performance does not meet my expectation,
should I consider using OpenGL instead?

If yes, I have no idea how to hook GL up with tkinter.
There is a tk OpenGL widget, but seems it is not easy to set up:

So I wonder if there are any documents about how to make Canvas work with
OpenGL or VTK.

Thanks
Beinan
