One crazy orbit in 1.4.0

Post #1by jromer » 26.12.2005, 20:14

Here's at least one example...

2.8G P-4 512k NVidia FX-5200
Celestia 1.4.1 running on WinXP (NVidia 61.77)
Celestia 1.4.1 running on Ubuntu6.06 (kind of...)

Yikes! Can you give a little more information about this orbit?

Is it the track of a flying saucer, perhaps? :)

Since I first posted, I restarted Celestia and the orbit seems to be OK again. I don't know what happened to cause Iapetus' orbit to do this. I have been unable to reproduce so I don't know what happened.

But here's another orbit issue I've never seen in previous releases. This one is reproducible. Celestia consistently seems to split orbit's at certain angles and distances, for example...

I think one of the fixes for Celestia 1.4.0 was that a 2nd set of orbit lines is drawn for the parts of orbits that pass in front of bodies. Without this fix in 1.3.2, orbits would be hidden by bodies. While I haven't had problems since the fix was tested and committed, this issue may be related to that fix.
