We have a new GEGL starfield filter that I made. It is partially based around David Wood's firework tutorial and the classic Windows XP screensaver.
https://github.com/LinuxBeaver/GEGL-StarfieldAlso the raw GEGL graph to making the filter is
- Code:
color-overlay value=#ffffff
noise-hsv saturation-distance=0.000 value-distance=4 holdness=4.5 seed=4
invert
levels out-high=4.10 in-high=0.3
gamma value=55
gaussian-blur std-dev-x=1.0 std-dev-y=1.0
crop
softglow
Enjoy!

Update, Filter now has a zoom motion blur slider!

Looking good man. My two most used filters when I want to create effects are HSV Noise and Solid Noise so seeing more uses for them is always good.
Maybe add a precompiled version so it's more easily accessible, I've never gotten into coding.

There you go!
For GIMP 2.10:
Version for Gimp-2.10.32 Win 64 Bit attached.
Place the file in Gegl plugins in a directory: C:\Users\YourName\AppData\Local\gegl-0.4\plug-ins
If you're missing the plugin-ins folder, create one.

I was just thinking if i would have moved those two larger stars to become Wilbers eyes he would be a constellation.

Wow @contrast_ your filter is very nice and simplifies the way I do stars BG in just one filter. Thank you very much

That picture feels so early 2000s Windows XP-ish I love it

Hey Rod! The credit really goes to contrast_
who created the Gegl filter, I just only compiled it for Windows users.

For various reasons, the best for me (taking into account Ofnuts' comments) is
Create a starfield plugin.

I would have said "from a sick brain of the ~90s", though
Thanks David for the kind word.

On that note, @contrast_ is possible to limit the stars colors within the Plank's law? To not have green nor pink or other strange colors.
The color range a bit something like below (Ok, the "white" part in the gradient is too big
)

As for an example, Albireo A and B in the Cygnus constellation shows well the difference in temperature (A is ~4000k and B is ~13000k)
Or the Antares system
Stars images are from Wikipedia

On a side note, plumbers got it wrong with their marking on the faucet, colors for hot and cold water should have been the opposite as the whole universe shows us

no. The filter is based on hsv noise and can only do what hsv noise can do.

That's OK

Starfield got an update that makes it work regardless if the background is opaque or not. It works on normal transparent backgrounds.
