That is to say...Jupiter.


I used the map of Bjorn Jonsson, which is 2880*1440 pixels: http://www.mmedia.is/~bjj/planetary_maps.html

Rendering time: one hour. Since it is a very simple scene...

I have a question about the atmosphere layout: what is the difference between "Bluesky horizon colour" and "Bluesky density colour"?

hello, I can't answer your question since I know about a much as nothing technical about terragen, but I know taht your scene is pretty nice. Maybe some other heading/ elevation of the sun and/or a more glowing atmosphere would make it a bit more interesting thoug (;

Great use of image maps ;).  Someone else will have to answer your bluesky question for you, though.  I personally would like to see a little more of an atmosphere in order to get a slight blur at the edge of the planet but I'm not sure what that would do to realism.

nice Jupiter image...add some moons if you can...

Nice image, but it looks flat...needs something to bring out the 3D side.  Thanks for the link.

Horizon color is the horizon color as opposed to the sky color.

So this is Disney World.  Can we live here?

Nice image, but I think your texture has seen one too many jpeg compressions - the colors are much less vivid than they should be. Take a look at the atrtached image - it's brighter than the one you've used, but it still isn't anywhere near as bright as it should be (it's been compressed as well, but probably not as many times).

Try taking a look at the stuff at http://maps.jpl.nasa.gov.

Thanks, but I already knew this site! It is in my list: http://elgastro22.free.fr/liens.html (3D/TEXTURES ET DONNEES ALTIMETRIQUES)
The texture of Bjorn Jonsonn has been made from the images that the Cassini probe took during its flyby, while the textures in your attached image has been made from the Voyager images!
About the brightness, I've decreased the sunlight strength to 1, since the 3.5 default value was too high and saturated the image.

@elegac - It looks flat.  Somehow your projection isn't accurate or is it that the one Harvey is showing looks flat?

Ah. Very good!   :)

Exactly what I was thinking. I think the problem is that on a real planet, you see the image projection get stretched as it approaches the horizon, as if you're looking at a flat projection through a fisheye lens, but your planet doesn't look like that. I think what you (elegac, that is, not calico) should do is try to get the mapping like that on your planet. It will look much more realistic that way.

Oh, et ta langue maternelle, est-ce que c'est le français? Parce que, en anglais, 'the map of Bjorn Jonsson' indique que c'est une carte qui vraiment représente la surface de Bjorn Jonsson. Si on veut parler d'une carte que Bjorn Jonsson a créée, ou une carte que Bjorn Jonsson possède, on dit 'Bjorn Jonsson's map'.
You know what's worse than not being able to do anything right or make anything good? Not being able to blame it on anyone but yourself.

Then I think THIS image is better: I changed the projection type to "spherical", instead of the default "through camera"!


Next steps:
-increase the thickness of the atmosphere
-add Io (with a realistic position and size)

Oups...autant pour moi...tu est français aussi? Est-ce que tu va sur le forum "Planète Terragen"?

This is somewhat better, I agree.  Spherical works best for these, from what I've seen.

This would look fantastic from IO's shoreline. 

Don't forget to coordinate the coordinates of your spherical maps with the location of your planets / moons.  These two things must always match up.  Just a reminder...

old_blaggard

Using spherical projection was a good idea ;).  Nicely done!

And you all thought my little blurb beneath my posts was a lie.
The world is round... so you have to use spherical projection.

invasion de français en ce moment ;)
