<div>it sounds like what happens when one leaks datasets,
filters, or other vtk objects that hold large amounts of
data. Could you share your script? <br>

<div dir="ltr">Hi,
<div><br>
</div>
<div>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?</div>
