Hello,<br><br>
I am not sure what method you are using to display your structured points
data set. Once you threshold to get a structured grid you have a lot of
primitives - perhaps when you display the structured points you are
rendering only the boundary and with the structured grid you are
rendering all cells? That would cause a significant slowdown. Also keep
in mind that the first render may take longer than subsequent ones when
immediate mode rendering is off (display lists are being used) -
this is the time to build the display list. <br><br>
If you only want to render the boundary there are filters you can use to
extract that. If you want to render all the cells, then you should
consider using volume rendering on the original structured
points.<br><br>

Actually, I am working on a 512*121*60 = 3.7 millions of points. It may
be more later...<br>
