Request: Antares (updated):

Post #1by Joey P. » 30.11.2017, 04:24

Could someone create an .stc that updates Antares to have the new artistic texture as well as Antares' blue star companion?

I already have the texture file:
https://drive.google.com/file/d/1ybYTyBPfgLEjF3zU_tgj_OGG2trWji1w/view?usp=sharing

Please take the information needed from https://www.aavso.org/vsots_alphasco

(note: do NOT include the nebula as I have another addon that includes it. I will upload the finished file to Celestia Motherlode.)

Thank you, Joey p.

The stc is quite simple:

Code: Select all

Modify "Antares" { Texture "antares.*" }


See the addon that I've included below.

Unfortunately, though, there are some problems with the surface texture image: it should be a power of two on a side and twice as wide as it is tall (e.g. 2048x1024 instead of 2000x964) and it needs to be an "equirectangular" projection. As it is now, it results in a "polar pinch" of the star's surface. See below.

When I tried to replace the existing texture with the new one, it would not work. Do you know how to fix it?

Make sure you're using the correct file name: either rename the jpg or edit your .STC file.

Except for that minor glitch it worked fine for me.

Still doesn't work, there might be a bug, but I think it could be OK.

Added after 11 minutes 46 seconds:
Anyway, where is the type B companion? There is no addon in the motherlode that includes it.

Here's a crude addon. I had problems finding good values for orbital parameters.

The minor glitch was in the .stc, not in your image, which is fine.

The texture specified in the Antares .stc was "antares.*" so in the updated antares.zip Addon, I renamed your image to match.
