Volume rendering blending artifacts #1208

Open alexanderbock opened 4 years ago

alexanderbock commented 4 years ago

Report from Alex @ NCMNS • Black square frame surrounding MW galaxy blocks out the background.

I assume this means that the transparent layers of the volume rendering are blocking the incoming Tully billboards

I cannot reproduce this issue (see pic attached). @alexanderbock, I propose we close this issue. Screenshot from 2020-07-01 09-39-45

Do you think this can be what he means?

@WeirdRubberDuck, I don't have permission to watch (access) the video.

WeirdRubberDuck commented 4 years ago

@jccosta sorry! Changed the link, please try again :)

The artifact is seen easier if the milky way image in scaled up. Also, the result differs when varying transparency:

Weirdest thing, it only happens if the fade-in effect is enabled for Tully galaxies. I tested w/ it disabled.

Disabled: Fade-In-Disabled

Enabled: Fade-In-Enabled

Np! Just happy the time I spent wondering about this and fiddling with values happened to be relevant :D

Seems to still be there, at least with the stellar streams data added.

Reopening for macos

Need to investigate if it is still an issue and whether it is actually still an issue on Windows.

Also: What is the proposed solution for dealing with the depth-testing issue?
