Asymmetric features in sim 22° halo about ice_halo_sim HOT 11 CLOSED

This issue cannot be reproduced on my computer. Could you show your settings for that simulation? I guess it could be a rendering problem.

This is my configure file:
Issue-config.zip

from ice_halo_sim.

Still it cannot be reproduced on my computer. I highly recommend you update your code to the latest version. Maybe it is caused by a minor bug and I have fixed it several commits before.

I'm still developing on this project. And codes are going better and better.

Issue closed.

Please feel free to comment here if still any strange arcs appear on your render result. I'll reopen this issue then.

from ice_halo_sim.

Maybe here is a reason: these arcs occurred only when I usecmake -D CMAKE_BUILD_TYPE=release.
However, there are still some very dim lines which can be noticed when the build type was not specified. The image below is rendered in 30M lights.
Here is the cmake output on screen which might have some usable information:

I also confirmed that this issue is located in Sim not Render

from ice_halo_sim.

After edited flag -O3 to -O2, -O1 and -O0 in CMakeList, I found that -O1 to -O3 lead to same result (and similar time). -O0 is better but spends doubled time.

Well..., interesting...
I tried again and rendered with intensity of 10.0, and I confirmed there were strange arcs. Seems much fainter than your case.
I'm trying to figure out why.

Issue reopened.

Here is my result. FYI.

It looks much fainter than yours.

from ice_halo_sim.

These arcs are also fainter in my color image.
Rounding error?

@XuebingZhao I have made major refactors recently. It seems all right with your case now. So I decide to close the issue. If there is still problem, pls comment here and I'll reopen it.
