Gas Giants

here is two variations on a theme
all 4 maps are 4k images

I hope I don't get accused of necroposting, but I have a couple questions about the process of gaseous-giganticus and cubic2erect. Firstly, I've getting the command-line thing sorted out. Using the cubic2erect command in the terminal is WAAAAAAAAAAY easier than the GUI. The Hugin program was confusing at best.

So the question is regarding the output: Is there anyway to control the size of the output of cubic2erect? It comes out as a 3216x1608 size .tif file. Can that be changed in the command line, not just the size, but also the file type? Currently, I've been opening them in GIMP, resizing it and exporting as png. Not a big problem, but curious to know if I can skip that process.

Love the work you've been producing. Thank you for being inspiring.

I find myself binge-creating gas giant textures now. Thanks.

It comes out as a 3216x1608 size .tif file

as far as i know there is not a way , i just resize the tif image and save it as a png

i start with a stripped image like this one

then i have a text file with the commands in it that i copy/past from into the terminal

Code: Select all

erect2cubic --filespec=PNG_m --erect=8.3.22.png --face=1024 --ptofile=cubic.pto

nona cubic.pto -o test
 
./gaseous-giganticus -b 11 -V -c 400 -k test000 -o gaseous
 
 
cubic2erect gaseous0.png gaseous1.png gaseous2.png gaseous3.png gaseous4.png gaseous5.png equirectangular



i edit the above commands as needed then copy / past into the terminal

Well, it's well and good. Personally, I'll start with a 200 x 1200 multicolored strip and go from there. Recently I used a piece of rhodonite and a photo of watermelon rind. (Why? Because, that's why!) I will find myself trying multiple versions of an original file to see what I can get. So far, I like where I get fairly wide belts and a lot of turbulence at the edges...of course, the output can get a bit messy.

I'll have to try the stripes. Putting a little more thought into what I'm doing might give me results I can be happier with.

Thank you again for your patience. (On the old forum, I remember your signature saying something about how you don't pitch linux, you let microsoft do that for you. I wish I had paid better attention; I would have gotten into Linux way sooner than I did. But thank you for that too!)

" I don't pitch Linux OS's to my friends,

I let MS Windows 10 do that for me!!"

that is my e-mail signature , and i might have had it also on the forum but i can not recall right now .

Apologies for resurrecting an old thread...

I'm the author of gaseous-giganticus. I noticed you guys seem to be manually converting cubemaps to equirectangular images.

Since Jan 2022, gaseous-giganticus has the -E option which allows outputting equirectangular images directly. From the man page:

-E, --equirectangular
Output an equirectangular image in addition to the usual cubemap
images. The image height must be an integer power of 2. The im‐
age width will be twice the height. The file will be named end‐
ing with "-eqr.png". (See -o option)

Perhaps you will find this option to be useful.

[John Van Vliet]

i will have to start using that option, thanks

Many thanks! I've been doing more work lately on my terrestrial worlds, so now I'll have to get back to the gas giants!

Gorgeous work! Been trying to bring my gas giants more in line with what they've got going on over at Orion's Arm. Having everything look like Jupiter or Saturn makes for uninspiring art. Thank you for being different!

And thank you, smcameron!

I upscaled and recolored John Van Vliet's gas giant texture.
