surface with edges representation in 5.7

gbug · October 15, 2019, 1:19pm

Hi!

I’ve noticed render problems with Surface with edges representation and unstructured meshes (vtu) in 5.7 (see screenshots):

Is it a known problem? Tried run with -dr option – didn’t help.

env: debian testing amd64 with KF5, PV downloaded from the site (py3.7).

I have the same problem as described by Gena Bug. I’m using ParaView 5.7.0 on Windows 10 with an NVIDIA GeForce RTX 2080 Ti.

Looks good to me. I checked software rendering (remote server) and Windows hardware rendering (NVIDIA Quadro M4000).

Parallel projection mode seems to cause the crosshair artifact. Indeed, for perspective view it works well.

Kyoshimi,
Well done. I have replicated the bug. i will write it up.

Bug has been written up here: https://gitlab.kitware.com/paraview/paraview/issues/19398. I wrote it up for ParaView 5.8.0, but it very likely will slip to 5.9.0. 5.8.0 is both already full, and coming quickly (early winter).

This can be worked around by going into Edit/ Settings/ Render View/ Line Offset Parameters, and changing -4 to a MUCH smaller number, such as -0.1.

Thanks for the workaround, it really helps. However I should mention that in my case mesh in perspective projection looks better than in parallel:

I wanted to mention that this is being worked in https://gitlab.kitware.com/paraview/paraview/issues/19437/ It has become a big enough issue we will try to get it into 5.8, out this winter.
