Summary0013264: pvbatch surface with edges, opacity draws funny in parallel
DescriptionA user found a bug with python. Basically, when you are showing surface with edges, with a non 1.0 opacity, the surface with edges draws with triangles rather than rectangles. This seems to only happen in parallel. In serial (pvpython), it works fine.

8 pvbatch's, a Linux cluster, 3.14.0.

I am including a python file that shows this, along with two screenshots - good and bad.

The reason is that when you turn on translucent rendering in parallel, the geometry is redistributed for ordered compositing (which is needed for good rendering in parallel for translucent data). That redistribution is change the type of cells from quads to triangles.

Developer notes:

D3 (vtkDistributedDataFilter) is used inside vtkOrderedCompositeDistributor filter. D3 uses vtkBoxClipDataSet to clip the cells. vtkBoxClipDataSet triangulates the cells during clipping and hence the problem.

Attached patch (BUG.13264.patch) adds a mode to vtkDistributedDataFilter to use vtkTableBasedClipDataSet, but that doesn't help since vtkTableBasedClipDataSet is buggy (try loading disk_out-ref.ex2 in parallel).
