The sky is falling

Unsnapped vertices in the sky dome? Version 3.1.0 from about a week ago.

[f-ojac]

Yep, this is known, I remember seeing it and a thread about it further down. Thorsten answered about it.

[daveculp]

Excellent. Thanks f-ojac.

Hmm, I noticed that as well when I took my first flight in 3.0. Is there a fix?

Unsnapped vertices in the sky dome?

My diagnosis says yes - someone who can affect the core probably needs to take a look at the skydome vertex structure at some point. I'm fairly certain this isn't a shader issue.

I've looked for this a couple times and never could spot anything wrong ... it probably requires someone to go in and strip out portions of the code to try to figure out if this a vertex problem, normal problem, shader problem, or maybe it's some subtle combination of multiple things, etc.

I took another look at this, and got lucky. I found a small indexing error which was causing one of the vertex positions to be wrong.

There's a fix now available in simgear/next.

wow-kudos, that's one of the longest-standing scenery "annoyances" I'm aware of!

[stuart]

Yes - and one I've looked at before but not been able to find. I guess all bugs are shallow with sufficient eyes and time staring .

[Hooray]

if you keep making so many changes in a single month, we'll need a new newsletter category just for all the things you've been working on

[Thorsten]

Terrific, Stuart! Many thanks!

[curt]

Awesome Stuart, thanks!

[f-ojac]

Great stuff, Stuart, thanks a lot!

[daveculp]

Thanks, Stuart! When I saw those nested loops in the skydome algorithm I didn't think there was enough coffee at Starbucks to fuel an investigation. Kudos!

[wlbragg]

Just compiled it, well done!
