Bug Description

Stellarium Version 0.11.0 The red ellipse of the Laomedeia's orbit is irregular

Added by Bogdan Marinov:
The problem with moon orbits noticed by me in the comments applies for all planets with moons. See bug #889712:
https://bugs.launchpad.net/stellarium/+bug/889712
The issue with Laomedeia may be unrelated, as it looks visually different and appears even if the time is not changed.

Wrong compared to what? Do you have light speed simulation turned on?

We need to decide what to do about moon orbits. See bug #834727.

Hi

The problem is not with the code, but with ssystem. The parameter names are case sensitive. Changing orbit_epoch and orbit_period to orbit_Epoch and orbit_Period under laomedeia solves the problem.

Oh, thanks! I think it's my fault.

O.K. I'm made a simple investigation of this issue and found troubles with rendering of orbits not related with typos for their elements.

Look at screenshots - it's like of troubles with rounding or double/float transformation.

I'm sorry, I couldn't reproduce the error. Changing the time shifts the orbit appropriately. Could you please elaborate on how to reproduce the result you got. I used the qt-4.8-compact branch (recently created).

It's from trunk

Shantanu Agarwal (shantanuag) wrote :

I use windows and therefore can't compile from trunk with the latest revision. Could it be that this problem occurs only in trunk? That's highly unlikely though.

Revision 5305 enable Qt 4.8 compatible mode for trunk.

Shantanu Agarwal (shantanuag) wrote :

Thanks for that. But I couldn't reproduce the error even in this branch. When I change the time, the orbit also moves in sync with the planet.
