Orbits and Labels colors

[t00fri]

How about decreasing 6.0f -> 2.0f here

Code: Select all

float distr = 2.0f * (labelThresholdMag - appMagEff)/labelThresholdMag;

Fridger,

I've found that using the value -7.5f gives some better result (I tried -6.0f, -7.0f, -7.5f and of course -8.0f). However, I still think the fading steps (fading range) are a bit too small. The fading process should last just a bit longer. It's too abrupt.

I did not tried your last suggestion yet.

My last suggestion INCREASES the fading step!

Fridger,

I think I'm very close. It's almost ideal now (just few more tweakings to do). Here's my modifications :

Code: Select all

 float appMagEff = 6.0f;
    switch (labelMask)
        {
            case Renderer::NebulaLabels:
                c = Color(0.85f, 0.35f, 0.29f);
                appMagEff = astro::absToAppMag(-7.5f, (float) distanceToDSO);
                break;
              case Renderer::OpenClusterLabels:
               c = Color(0.38f, 0.71f, 0.58f);
               appMagEff = astro::absToAppMag(-6.0f, (float) distanceToDSO);
                break;
           case Renderer::GalaxyLabels:
           default:
                c = Color(0.1f, 0.85f, 0.85f);
                appMagEff = appMag;
                break;                  
        }                         
          if(appMagEff < labelThresholdMag)
          {
              //cout<<labelThresholdMag<<endl;
           // introduce distance dependent label transparency.
           float distr = 4.0f * (labelThresholdMag - appMagEff)/labelThresholdMag;
           if (distr > 1.0f)
               distr = 1.0f;

I used -7.5f for the nebulas, -6f (to be tweaked ?) for the clusters, and 4f for the fading steps.

Yep, I'm almost certain the parameters I used above are ideal. No more crowdedness. The fading preocess is beautifull, everything is clearly visible and the spatial distribution (depth illusion) is very good too. What do you think ?

[t00fri]

Note that if you make the appMagEff function different for Nebulae and Clusters, they appear/fade at DIFFERENT distances...

i.e. they obey different visibility rules.

Of course ! That's what I wanted, since there are more clusters (larger crowdedness) than nebulas (at least, with the databases I'm using).

The -6f value used for the clusters may be tweaked a bit. I don't mind much about it, since it's actually very good. A value a bit larger (-7f) could be very good too, I believe.

[t00fri]

Your settings look GOOD.


Have a look with the galaxies: with 6.0f -> 4.0f the fading step is also slower for galaxies. If you prefer the previous settings, I can easily make a respective code change that preserves the galaxy settings.


Bye Fridger

[Cham]

I think it's perfect, even for the galaxies !

Having them fading a bit slower is great too.

Fridger, I think we have done it. We only have to wait for Chris comments. Do you agree ?

And what about the asteroids and comets ?

[t00fri]

Last not least, COLORS again.

I think that the green color for the clusters is too close to the galaxy color, if that is darkened in the fading regime!! I would suggest to make the green more bluish, perhaps. Also did you check the color harmony with the grid color?

Yes, I checked against the grid. I think it's ok. Making the clusters labels a bit bluer would close them to the galaxies labels (not good). Making them greener would close them to the location labels. And take note that, at the scale which let us see the clusters labels, there isn't much galaxies labels visible.

EDIT : Here's an example : (slider put to the max). There is no confusion possible here. Or if you prefer, I could make the clusters labels a bit greener ?

[ElChristou]

All this seems very nice but...

What would be really cool would be all labels and orbits colors harmonized with the current selection's color (to not break the palette on screen)...

All those purple, red, blue, yellow, green and other labels and orbits just fight each others and I cannot stand anymore my screen (it break the harmony of my Feng-Shui interior)...

I also tried another direction: I made the green bluer to start and then added some red. This gives a green-gray shade, which fits nicely to the red of the nebulae labels!

Finally I reduced the overall luminosity somewhat.

Have a look:

c = Color(0.416f, 0.568f, 0.544f);

Really?
Joke of course!

Sorry, good job mates! Tx!!

[Cham]

I just changed the cluster labels to Color(0.37f, 0.71f, 0.53f). It's nice.

I'll try your color in few min.

[t00fri]

Actually ...my Feng-Shui also signals on and off that it would prefer a somewhat "quieter" color harmony.

Of course we know it's hard, BUT...


Christophe, how about joining this proven collaboration for some further joint color trials?

Bye Fridger

[Cham]

Fridger, I just tried your color. It's nice but it's looking a bit "dead". I think I prefer my last suggestion :

Code: Select all

Color(0.37f, 0.71f, 0.53f)

By the way, ElChristou gave me an idea (I can't tell if it's hard to code, though) :

Is it possible to highlight the selected label in vivid red, like the selection marker ?

I've just waking up from a "p'tite sieste" after a canard ?  l'orange at my father's home... cognac to help the digestion... hard...

In a few hours I'll try a full set but indeed it's not so simple...

I think we definitely need some "quieter" colors. It looks simply too colorful. At least for "Old Europeans", perhaps

How about Christophe's vote. Here is my quieter suggestion for Nebulae (red) and clusters (green-gray)
