[Paraview] How to re-render or update the window through python script

[Junyi Han]

Hi,

I'm using python script to read data files. Render() function is called as
many times as the number of files. I found that after I call render() for
40 or 50 times, the speed of rendering is very slow. Is there a way to
solve it? Instead of calling Render() function several times, is there a
way to update or re-render?

Best wishes,
Junyi Han
