Jupiter and Neptune textures, anyone?

Guest · Post #1by **Guest** » 20.11.2002, 06:38

Hello!

Last night I tried my best to create ring textures for Jupiter and Neptune and guess what? I am no good at creating textures!
Could someone create textures for the rings of Jupiter and Neptune? Please? :roll:

Neptune? Does Neptune have rings?

Guest · Post #3by **Guest** » 20.11.2002, 08:01

Yes. Neptune has complete rings. Not faint arcs. You might learn more at http://www.seds.org/billa/tnp/neptune.html

This picture shows a twisted ring around Neptune. Like the above link, this picture is hosted by The Nine Planets.

Well if you have photoshop open a new texture, select transparent background, at 1024 x 64 and draw a couple of faint white lines next to each other...blur it a bit and save as a .png file...thats it...jupiter may be a bit same, all depends on what you want for detail....Who knows at one point I might make some of my own and post them here...

Well here's some pics of the new Neptune rings i just made. I created a low bright texture to make them faint but visible

I used this pic as a reference:

Here are the screenshots:

Let me know what u think and if u like it i?ll post the texture and ring declarations

not bad... not bad at all. actually, they look really good. but how accurate are they?

praesepe · Post #8by **praesepe** » 20.11.2002, 22:29

I used the data from Solarviews to make the ring declaration for the .scc file, see it at http://www.solarviews.com/eng/neptune.htm so they are accurate

Ok, here you are :wink:

The PNG texture: http://www.la-guarida.com/Celestia/Text ... -rings.png

The ring declaration:

Rings
{
Inner 41900
Outer 62930
Texture "neptune-rings.png"
}

It is me again, the guy who created this topic. OK, how about making a Jupiter ring texture? :cool:

chris: Could you include the Neptune rings in 1.2.5 final?

Wow! Looks very nice - excellent job!
Thanks praesepe!

Well, it looks great from here, anyway...
I can't seem to get the rings to show up on my pc. I added the declaration to the solarsys.ssc file and saved the neptune-rings.png to lo/med/hi res folders (just in case :wink:

) but I'm still not seeing the rings. (Saturn and Uranus are showing their rings fine, btw).

Here's what I've got for Neptune in the .ssc:

"Neptune" "Sol"
{
Texture "neptune.jpg"
Color [ 0.75 0.75 1.0 ]
HazeColor [ 0.6 1 0.75 ]
HazeDensity 0.35
Radius 25225
Oblateness 0.027

CustomOrbit "vsop87-neptune"
EllipticalOrbit
{
Period 164.793
SemiMajorAxis 30.0690
Eccentricity 0.0086
Inclination 1.7692
AscendingNode 131.722
LongOfPericenter 44.971
MeanLongitude 304.880
}

RotationPeriod 16.11
Obliquity 28.03
EquatorAscendingNode 0 # 49.235

Albedo 0.62
}

Rings {
Inner 41900
Outer 62930
Texture "neptune-rings.png"
}
}

What did I do wrong? Please help!

Cheers!
Sean

PS: I would love to see Jupiter's rings as well...

praesepe · Post #14by **praesepe** » 21.11.2002, 03:58

Ok, i?m on it. I saw other requests for Jupiter rings so i'll start a new texture

Give a few tries and i'll i post the results :wink:

try miving the rings section so it will look like this:
"Neptune" "Sol"
{
Texture "neptune.jpg"
Color [ 0.75 0.75 1.0 ]
HazeColor [ 0.6 1 0.75 ]
HazeDensity 0.35
Radius 25225
Oblateness 0.027

CustomOrbit "vsop87-neptune"
EllipticalOrbit
{
Period 164.793
SemiMajorAxis 30.0690
Eccentricity 0.0086
Inclination 1.7692
AscendingNode 131.722
LongOfPericenter 44.971
MeanLongitude 304.880
}
RotationPeriod 16.11
Obliquity 28.03
EquatorAscendingNode 0 # 49.235
Rings {
Inner 41900
Outer 62930
Texture "neptune-rings.png"
}
Albedo 0.62
}

maybe that will work...

Yep - that did the trick! Thanks!

I arranged it that way after comparing it to the way Uranus was written - I guess this doesn't apply to Neptune?

Looks fantastic! Thanks again!

Rings {

Is neptune-rings.png a PNG (short for Portable Network Graphics) that is 1024x64? It is the only ring texture size supported by Celestia.
