stars.dat ver 1.20

[HB]

The new stars.dat version 1.20 doesn't work. Perhaps a few bytes to much by stellarclass from some stars?

Added later:

Yes, and I have build Celestia compiled from the latest CVS files.

"it works fine for me"

I just now used anonymous CVS to download the entire celestia directory tree from scratch (I did not do a partial update nor did I try to use the nightly tarball) and rebuilt Celestia under Windows XP with VisualStudio 2003 using makerelease.bat. Celestia started and displayed stars with no relevant error messages.

The console log (~) said

112524 stars in database
Loaded cross index data/hdxindex.dat
Loaded cross index data/saoxindex.dat

complained about the exoplanets with no primaries
loaded many ssc files
and solar system surface textures.


There are, umm, problems when trying to view a star close up, but I know Chris is in the middle of modifying that code. (Celestia draws an irregular white 3D shape inside a glowing photosphere.)

Curious indeed. I only see that when I specify a mesh for a star. Could you share a screenshot?

Not until this evening, ~7 hours from now. Sorry.

(I'm not set up to build Celestia at work.)

fwiw, there were no error messages in the console log. I think it *might* have looked like Phobos, but I'm not sure. Phobos happened to be the last object loaded, according to the console log.

I first noticed it when I did a GoTo of a random star, just to make sure stars.dat was loading properly. Then I typed H G (GoTo Sun) and saw it there.

It _is_ Phobos:

[selden]

Yup. That's what I saw, too.

Selden you'r right again.It seem's I've got a download or ZIP-problem.
After download again its working ok.
But it seems dat when dumping the stars.dat to a text file some of the StellarClass info isn't complete. By some of the star a "V" is missing. I didn't check it completly to find other missing items.

Another problem arose as wel.The latest tool, Makestardb v1.3, is complaining about linking problems during compilation. Something about textures and image. It become quite late to sort out this problem in more details.

Hans.

There are many missing data in the original Hipparcos catalogue. Celestia used to assign a luminosity class of "V" if no luminosity class was given, but this was often wrong.

It should be fixed in the latest CVS build. The problem arose because the model wasn't initialized to InvalidResource in a constructor. I also changed the rendering code so the photosphere isn't shown for stars with meshes.

I just checked in a fix for this. You should be able to build makestardb again.
