Celestia v1.4.1 final: bugs

[selden]

When star labels are selected in the Render/View Options menu, some stars are not labelled that should be.

For example, when I select Sirius, its name is not drawn although "Sirius" is listed in celestia.cfg

If I insert "Sirius A" into the list before or after "Sirius" or replacing it, the label "Sirius A" is drawn.

Hmmm. My own reply somehow got lost. Maybe I forgot to click on Submit?

Anyhow,

It seems that Barycenters aren't labelled.
ALF Cen isn't labelled either, for example.

I am trying to build Celestia 1.4.1 from source under Slackware Linux 10.0 with KDE 3.2.3. I configure it with:

Code: Select all

./configure --prefix=/usr/local/celestia --with-kde --with-lua=/usr/local/lua

Configuration works fine, but compilation aborts with this error:

Code: Select all

[...]
celsplashscreen.cpp: In member function `virtual void
   CelSplashScreen::update(const std::string&)':
celsplashscreen.cpp:59: error: no matching function for call to `TextItem::

   std::allocator<char> >&)'
celsplashscreen.h:37: error: candidates are: void TextItem::setContent(const
   QString&)

The comets tails disappear in some angles.If you centralize the comets??nucleus and drag it a bit,the entire comet vanishes,or at least the tail and coma rendering.The Celestia 1.4.1 patch didn??t fix it.

The comet tail has to vanish along the direction where you are looking "head on" and similarly "tail-on" (180 degrees relative to "head-on") . I am sure that during my extensive code tests everything looked perfectly reasonable at ALL angles...

This is fixed with my automatic star labeling changes, which I'll be checking in soon. The LabelledStars list in celestia.cfg is no longer necessary. The first star name is chosen for the label; thus with the default starnames.dat, ALF Cen is labeled with 'Rigel Kentaurus A'

Thanks!

Moon orbits are drawn incorrectly, and will sometimes jitter. This is most noticeable when the orbit radius of the moon is small and the orbit radius of the parent body is large. The half orbit is drawn correctly, but the full orbit is not.
