Hi all,<br> I'm using a program to plot a huge number of points using vtk. My program is a two threaded program, in which one thread reads data from a file and another thread plots the read data using vtk. My program seems very non-responsive due to the huge loop inside the displaying function, which plots the large number of data points. Do you have any idea to improve my code so that I can make if more responsive to mouse events (such as zoom in and so on..)<br>
<br>Thanks,<br>Diluka.<br>
