Hi David,<br><br>Have you tried turning off labels while camera manipulation is happening and turning them on only after a still render?<br><br>hth,<br>Dave DeMarle<br><br><br><div><span class="gmail_quote">On 8/25/07, <b class="gmail_sendername">

Thanks for your reply, Berk. We've thought of that -- you're quite<br>right that 1000 labels is pretty useless. However, we need an efficient<br>way to turn the labels on and off for our use. For example, we may have
<br>10,000 points, each with one or more value(s) associated with it. Our<br>users want to see these values without having to select the points or<br>triangles (in our application, that's gonna get awfully tedious). When
<br>all 10,000 points are visible, they're so close together that there is<br>no point, but when the user zooms in to get a closer view, and can see<br>perhaps 100 points, we'd like the numbers to show up next to the points
<br>automatically. How might one accomplish that? Thanks again!<br><br>DG<br><br>Berk Geveci wrote:<br>> In paraview, we decided to only show labels of selected cells/points<br>> to overcome this issue. I don't think showing more than a few dozen
