Summary0007789: D3 is broken with opacity not 1
DescriptionThis needs to go into ParaView 3.4.2

Run ParaView client/server. I am using 4 servers.

Open disk_out_ref.exo. I am coloring by Temp, but it shouldn't matter.

Filter D3, Divide Cells. Apply.
Change opacity to 0.50. Touch the main window, for instance rotating the object slightly. The object totally disappears.

I tried volume rendering, but it took so long I gave up. Probably killed the server.

I tried changing the opacity from 1 to 0.5 using mesa and 12 pvservers. As I rtotated it, it quickly hung. I tried with 4 servers, and it seemed OK.

So, to replicate this, try using more servers.

Sorry, forgot to mention this is on the ParaView trunk.

This should now be fix. There were issues with updates when OrderedCompositing was employed which resulted in deadlocks. Tested with 12 servers and seems to work for me now.

This now works - sort of.

Do as listed below. Then, change opacity back to 1.0. The object will get really strange - opaque. Click off the Interpolate Colors button, all is now normal, click on the Interpolate Colors button, all is still normal.

The check to use previously generated texture did not take into
consideration if the last-used-opacity was different than the current one
explicitly. It relied on it being different from the opacity of the LUT, which
worked in most cases but failed in some. eg. change opacity to something
(say .5) and then back to 1.0. Fixed that.

Tested client/server. Looks good!
