[Paraview] Opacity Issues

[Paluszek, Lukasz]

It doesn’t happen all the time, I suppose you need a fairly large surface dataset. I managed to reproduce the problem on a wavelet source (attached state file), try increasing the number of elements if you do not see any artifacts. I have bult Paraview from source on OpenSuse 13.1 but also cross-checked with the Linux binaries from Paraview.org and had same issues. There was no problem with the osmesa-llvm flavor though.

Hello,

In Paraview 5.1.0 with OpenGL2, I have black slices throughout the model when opacity is on in parallel mode (see attached picture). When switching depth peeling off, the black slices disappear but the image gets blurred and some pixels glow with random colours. I can’t reproduce it with 5.0.0, my NVidia driver is 361.42. Does anyone else experience similar behaviour?

Interesting, I haven't seen this before. Does it happen for all depth peeled transparent rendering, or just certain scenes? If it's only certain scenes, can you provide a state file or details on the scene?

Also, which OS is this?

Thanks,
Dave
