Surface with Edges creates extra edges
When loading a parallel dataset and showing 'Surface With Edges', extra edges are present at cells which are at the border of data partitions. It looks like the edges are "going into" the mesh. These extra edges make it impossible for our users to really understand the structure of the mesh on the surface.
This is present in Paraview 5.6.2, but for some reason it's hard to create the right situation where it occurs. It surprisingly is most obvious in Paraview 5.8.0.
If the mesh is even larger, the errors look even worse. There are many more extra edges. Below is a similar mesh, except that the number of cells were increased by 1000x. It looks like there are small fences along the data partitions.
Here is the dataset used for the first two images: rti_small.tar.gz
Camera angle file used for first two images: viewpoint.pvcvbc
I can't include the large mesh because it's about 12GB.
How to reproduce:
- use Paraview 5.8.0 (can use in serial)
- load the dataset
- rotate the mesh at an angle
- zoom into the mesh until you see the extra edges
- or you can download viewpoint.pvcvbc, load it with the 'Configure custom viewpoints' button, and click on the newly created Viewpoint
