Recently in another thread I posted about a video of Sebastian Lague, where a generative algorithm allows for the creation of animated stellar granulation (see 15:46 in the video).

Later, midtskogen answered saying that this was probably too computationally expensive for the cadence of SpaceEngine renderings. So I searched for possible alternatives.

Using the Kuramoto-Sivashinsky equation it appears that animating granulation (at least mimicking similar behaviour) in stellar surfaces is archivable on the run. You can see the animation and implementation here.

Is this in the realm of possibilities SpaceEngineer?

Maybe it's hard because in Space Engine you can go backwards in time and maybe the algorithm doesn't allow that... Unless if the animation takes the time scale as absolute even if it's unrealistic  :D

Some suggestions I would like to see:
Planetary interiors
Atlas mode (features alternate textures for Solar System planets, such as topographical and false color maps for terrestrial planets and moons, Continental Drift and thematic maps for Earth, historical and false color maps for giant planets based on either Pioneer, Voyager, Hubble, Cassini, New Horizons, Juno imagery, etc., mostly reused from Celestia Origin)
The Sun under various light spectra, with those textures represented as transparent overlays (for visible light, the Sun texture from Solar System Scope is used to represent the Sun's chromosphere), also flares and prominences on the Sun's surface
Venus' surface texture is now reoriented (its map texture is made upside down so that it is rendered right-side up)
Corrected models for certain asteroids and comets (again mostly reused from Celestia Origin) and new textures for certain dwarf planets like Haumea, Makemake, Eris, Sedna, Gonggong, etc. based on either Snowfall or Kexitt's textures (also from Celestia Origin).
Redesigned and more visible ring textures for Jupiter, Uranus, and Neptune (again also from Celestia Origin)
A redesigned Milky Way texture featuring a spiral bar
Asteroid and Kuiper Belts and Oort Clouds (seen only from far away)
Interactive educational features

More of a question and if the sim doesn't have this a suggestion....is there any way to create a "flight plan" on SE?  For example.  I want to do a space flight from one side of the galaxy to the other going through the densest clusters and the center of the galaxy.  I would like to be able to input the amount of time this flight should take (my you tube upper limit for video length is 12 hours, so any video I would do would have to be at or less than that) and then the sim would adjust the flight time accordingly and fly me there in that amount of time- is anything like this already in the program or can it be added?

The planet editor should be altered to raise climate change awareness: altering either a planet's greenhouse gas concentration, orbital distance, and/or even its star's composition and luminosity would also affect its temperature, sea level, and ultimately its habitability. For example, this would potentially terraform uninhabitable worlds into possibly habitable worlds, and conversely, the opposite can be done to worlds that are already habitable, either culminating in either an Ice Age (increased ice cover lowers sea level by freezing seawater in ice) or a Snowball (the entire planet freezes over) planet if the planet is made too cold or a flooded (the ice caps melt, raising sea levels) or a Venus-like (the oceans boil away) planet if the planet is made too hot.

More realistic reactions to the properties of a planet is welcome but it'll hardly raise awareness given how niche Space Engine (and the planet editor) are.

How about habitable zones boundaries for planetary systems indicating planets that are habitable (green=habitable, red=too hot, blue=too cold), antique-like constellation art, and the Earth being reimagined as a Google Earth clone.

3.add back unique procedural planets
they where removed in 0.990 so add them back
now planets look very similar but back then they look unique
4.seperate volumetric resolution
separate them to galaxy resolution and nebula resolution

Planets are still procedurally generated. As for nebulae, it isn't easy finding a set of numbers that result in a nebula that doesn't look weird.

but they are not unique they are lots of the same planet like i ran into 10 blue greyish planets

There should be a search feature for individual procedural planets, moons, stars, and/or galaxies.

Then keep looking; desolate planets are common in the Universe.

I dont know why it is, but .980 seemed to have a lot more variation with much nicer colors and more photogenic planets.  I think there should be an option in the menu to create procedural worlds more like that.

How about a Star Trek-like planet classification system?

somebody that i know recently made a song that sounds somewhat familiar with the space engine ost
and i thought that it could be amazing having it in the soundtrack, dont you think?

here's the song:

Trees, rocks, roads, and buildings being rendered on Earth. Also, various animals (including prehistoric animals if one looks at it millions of years ago via Continental Drift) and vehicles roaming around (indicating the presence of humans).
