[Paraview] Re-render when hovering over color legend

Tue Apr 12 08:24:11 EDT 2016

Hello,

I noticed that Paraview redraws a scene whenever the mouse cursor passes over the color legend or a text source. This is especially noticeable when one performs volume rendering on unstructured grids which takes some time to render. Each time I accidentally cross the color legend or a text source with the cursor, Paraview redraws the scene twice, wasting a lot of time.

To reproduce you need to volume render an unstructured data set which is big enough to take a few seconds on your machine. In my case I generated a wavelet source with the following extents:
-100 10
-100 10
-100 10

Thresholded the whole RTData extent to convert into an unstructured grid and volume rendered the Threshold. Once you see the volume render hover the mouse cursor over the color legend and your scene will be re-rendered.

Regards,
Lukasz
