A Triton like moon around a Neptune like planet

the Gas Giant was made using "GaseousGiganticus"
and the moon in Blender

if people want i can post a thread of fictional moon's ( earth and kbo like )

say 5 or 6 of each for people to use
4k tex and normal

still having issues with making Io like and Europa and Ganymede like procedural textures

John, since a long time... I have a dream...about EXO planet systems!

The idea is quite similar to my successful procedure of computer managing large numbers (10937) of galaxies (and also globulars) for Celestia and with much enhancement also for celestia.Sci .

  • Firstly, computer scripts (perl, python,...) read out and calculate locations, sizes, colors, spacial orientations etc from catalogs. This happens without human interference, even for very large numbers of objects, since the proper galaxy catalogs exist. Analogously, we have large EXO planet catalogs containing this type of info.

  • The tricky part comes with the 3d displays. For galaxies, I reduced the huge work of individually rendering 10937 galaxies to rendering only the Hubble types (my "templates") with fast shaders. Since for every galaxy the respective Hubble type is found in the catalogs, we end up with large numbers of properly oriented, properly sized, correctly located and pretty well rendered galaxies!

  • For EXO systems, the analogs of the Hubble types are different of course: For example, we have habitable templates, templates with lots of oceans or mostly rocky etc. Again given a map of these relatively few "EXO templates" onto the realistic EXO planets from catalogs would leave us with a probably successful project of rendering just a modest number of template-EXOs. The project will exhibit scientific rigor and yet, it will still please hobby astronomers / astrophysicists! ;-)

  • I think John, you would be an ideal member of such a project ;-)

so far i only have good looking Gas Giants and earth like planets

as for asteroids , i only have rocky and metallic ones , the "rubble pile" ones are not looking good

large moons are a issue still , ones that are like Earths moon look good and so dose the "Triton" like
but "Io", "Europa", "Ganymede " type are not looking good that is why i have not posted any of these

Small moons ( rocky asteroids basically ) need a mesh to look decent i have been able to get the cmod's down to about
6 meg before loosing the shape .

I think John, you would be an ideal member of such a project

sounds good to me

so something like a selection of say 5 to 10 different types gas giants and rocky and earthlike planets
for a script to randomly ( psudo random using a seed so that every exo system is the same on every visit ) select a texture for the type of exoplanet .

Great! It would be even better if Andrew (aka ajtribick) would also be interested. He's an expert on scripting, on EXOs, on celestia.Sci (and on many other topics, of course ...)

Although one would be talking (initially) only about order ~10 EXO "template" types, their graphical surface design might not be easy altogether. Starting from a list of known properties, the resulting planets and their stars should speak for themselves. Will say, clearly exhibit (only) recognizable visualizations of the basic properties.

How might the list of basic properties look like?

i am planning on starting with the easy ones first
1) the hot small rocky " venus like"
2) the cold small rocky " Mars like"
3) the habitable zone " earth like" and "super Earth's"

4) This is the question:
I was thinking of using "Sudarsky's classification" ... sification
As a starting point

However this dose not include the HOT Jupiter's and small Neptune's

A venus like example( 2k reductions from the 4k images ) :

the clouds

and normal
2k.VenusLikeNormal1.png [ 2.37 MiB | Viewed 2311 times ]

as to Texture size i am working with 4k maps
would you prefer 2k maps do to file size and the large number of textures
