Activate only one Constelation

[Cham]

Thanks Andrea.

Do you know the other commands ? How to change back the colors to the default ?

Thanks Andrea.

You are welcome, Cham.
regarding the default setting, I think that actually the only way is to put a"#" in front of every command line.
Not so nice, I agree.
Perhaps m3ntol....
BTW, Cham, could you please check if you have the same problem I submitted a few messages ago, i.e.

Code: Select all

setlabelcolor { item "galaxies" color [0.24 0.63 0.05] }

gives this error, crashing Celestia:
"Bad Parameter Error"

Thanks a lot.
Bye

Andrea,
with your code (is it really a CEL, or a CELX ?) :

Code: Select all

{
setlabelcolor { item "galaxies" color [0.84 0.63 0.05] }
}

nothing happens with this code, defined as a CEL script.

And what about alpha effects for the constellation labels and lines ?

How to set a different color to the constellation label, and a separate color for its lines ?

Cham, it's a cel script that I applied to the m3ntol's addon: add_2.zip as given in his message posted: Fri Feb 29, 2008 10:31 am

And what about alpha effects for the constellation labels and lines ?

Cham, what do you mean with alpha effects on labels and lines?
Their transparency?
If it?€™s so, don?€™t know how to obtain this, sorry, I think it?€™s not available, yet.

How to set a different color to the constellation label, and a separate color for its lines ?

In the above given link there is too this possibility.

Sorry, I don't find it.

What I mean is to define a different color for Orion's label (say), and another one for its lines, without changing the others.

Cham, this
http://celestiaproject.net/forum/viewtopic.php ... c&start=15
makes only half of what you want, I think, because it changes the same way BOTH label AND lines color of the chosen constellation, sorry.
Give a look at my image.
I think you should need cel commands like these:

constellationlinecolor { color [0 1 0] set "Ursa_Major" }
constellationlabelcolor { color [0 0 1] set "Cygnus" }

Ahaa !

Code: Select all

{
constellationcolor { clear "all" }
}

sets back all constellations to the default rendering. Good !

You are right, Cham, I missed it.
This makes me think that we should need some update to cel script manual.

This makes me think that we should need some update to cel script manual.

I'm afraid that many new commands (CEL, CELX, SSC, STC, etc) are't known enough and that they'll become forgotten, after a while. The Wiki books could help, but it isn't enough, since the Wiki tends to be very technical and may terrorise the "typical" users.

I agree, but we need an English speaking guy for updating Don Goyette's Cel_Script_Guide_v1-0g.doc, IMO.

Okay, for reference, here are three simple CEL scripts I made permanent in my installation. They should be very usefull in the classroom !

1. This CEL script changes the colors of the Zodiac and few "important" constellations :

Code: Select all

# Title: Show the Zodiac and few other constellations with a different color

{

constellationcolor { color [ 0.2 0.5 0.6 ] set "Aries|Virgo|Scorpius|Capricornus|Cancer|Leo|Libra|Sagittarius|Pisces|Gemini|Taurus|Aquarius" }

constellationcolor { color [ 0.54 0.24 0.12 ] set "Orion|Cassiopeia" }

constellationcolor { color [ 0.42 0.36 0.24 ] set "Ursa_Major|Ursa_Minor" }
 
}

2. This CEL script erases all the constellations, except the Zodiac and few others :

Code: Select all

# Title: Show the Zodiac only, plus few others ...

{
constellations { clear "all" }

constellations { set "Aries|Virgo|Scorpius|Capricornus|Cancer|Leo|Libra|Sagittarius|Pisces|Gemini|Taurus|Aquarius" }

constellations { set "Orion|Cassiopeia" }
constellationcolor { color [ 0.54 0.24 0.12 ] set "Orion|Cassiopeia" }

constellations { set "Ursa_Major|Ursa_Minor" }
constellationcolor { color [ 0.42 0.36 0.24 ] set "Ursa_Major|Ursa_Minor" }

}


3. This CEL script reset everything to the default rendering :

Code: Select all

# Title: Reset the constellations to the default rendering

{
constellationcolor { clear "all" }
constellations { set "all" }
}


I think this new capability of Celestia will be VERY usefull !

[m3ntol]

Well, changes done! Sintaxt is as Chris described:
setlinecolor { item "equatorialgrid" color [0 0 1] }
And that's all folks

Hello m3ntol, sorry but I didn't try the setlabelcolor for galaxies before, and now I see that

Code: Select all

setlabelcolor { item "galaxies" color [0.24 0.63 0.05] }

gives this error, crashing Celestia:
"Bad Parameter Error"
I checked and I'm sure that the error is due to that command line.
I supposed that in the addon perhaps the galaxies name could be wrongly written, so I tried galaxes and galaxyes, but without results.
Any idea?
Bye and thank you.

Andrea

Hello,
I was on vacation this weekend, but now I'm back

I've try the command and works fine for me. No idea why fails on your system. Please, try this script:

Code: Select all

{

  cancel{}
  renderflags { clear "boundaries|grid|orbits|planets"}
   labels { clear "asteroids|comets|constellations|galaxies|moons|planets|spacecraft|stars"}
   unmarkall {}
   set {name "ambientlightlevel" value 0.0}
   setfaintestautomag45deg {magnitude 9.0}
   set {name "fov" value 80}
   set {name "stardistancelimit" value 1000000}
   
   timerate { rate 1.0 }

 setlabelcolor { item "galaxies" color [0.24 0.63 0.05] }
 
  renderflags { set "boundaries|grid|orbits|planets|galaxies"}
  labels { set "boundaries|grid|orbits|planets|galaxies"}
   
 }

I can see SMC, LMC, Sagittarius and other galaxy labels in green. Please, ANDREA, try it without adding anything, may be the error is in other part of your script file.

WOW! lot of new post... i'm going to read it...

[m3ntol]

m3ntol,

I've added quite a lot of new Celx methods to Celestia 1.5.0, but I only added the corresponding Cel commands for a minority of them. Would you be interested in adding the remaining Cel commands? You'll find a list of the new Celx methods added to Celestia 1.5.0 here:
http://celestiaproject.net/forum/viewtopic.php?t=10936

Ok,
let me take a look. As I see I only need to add new commands and change the parser to read it.

[m3ntol]

And what about alpha effects for the constellation labels and lines ?

How to set a different color to the constellation label, and a separate color for its lines ?

Alpha is not supported yet.

About setting different colors for lines and labels, you can usa a combination of constellations commands and this two new ones:

setlinecolor { item "constellations" color [0 0 1] }
setlabelcolor { item "constellations" color [1 0 0] }

I don't see how it should work. Can you give a specific example, for "Orion", say ?

[m3ntol]

Try this cel script:

Code: Select all

{

  cancel{}
  renderflags { clear "boundaries|grid|orbits|planets"}
   labels { clear "asteroids|comets|constellations|galaxies|moons|planets|spacecraft|stars"}
   unmarkall {}

   setfaintestautomag45deg {magnitude 9.0}
   set {name "fov" value 80}
   set {name "stardistancelimit" value 1000000}
   
   timerate { rate 1.0 }

setlinecolor { item "constellations" color [0 0 1] }
setlabelcolor { item "constellations" color [1 0 0] }
constellations { clear "all" }
constellations { set "Orion" }

renderflags { set "constellations|boundaries|grid|orbits|planets|galaxies"}
  labels { set "constellations|boundaries|grid|orbits|planets|galaxies"}
   
 }


[Cham]

m3ntol,

what I mean is to set different colors for several constellations. For example, all constellations are drawn with the default colors, while "Orion" is set with different colors (with lines and labels having different colors too).

[m3ntol]

Not supported yet

You can set differents colors for each constellations, but labels would diplay same color than its constellation. Or you can set a color for all constellations and a different one for all labels, but not two things at time.

[Cham]

Ok, that's what I presumed. Thanks.

Personaly, I don't need the transparency (alpha effect). Just to set a different color to the labels, for each constellation. Thanks a lot for your efforts, it's really appreciated.

Hello m3ntol, ?€¦

Code: Select all

setlabelcolor { item "galaxies" color [0.24 0.63 0.05] }

gives this error, "Bad Parameter Error"
I'm sure that the error is due to that command line. Andrea

Hello, ... I've try the command and works fine for me. No idea why fails on your system. Please, try this script?€¦Please, ANDREA, try it without adding anything, may be the error is in other part of your script file.

Hello m3ntol, my fault, or better, it?€™s a fault of my poor sight.
I didn?€™t find the mistake until I printed with large characters my script?€™s command line, that I found to be this:
setlabelcolor { item "galaxies" color [0.71 0.23 0.23] )
As you can see the last parenthesis is a round bracket instead of a curly one.
In the example posted here I copied your command line, that obviously was correct, while the one I used in my script was wrong.
A stupid error, sorry for your time lost uselessly, beg your pardon.
Bye

Andrea
