Hello, I'm new here

[TT1]

Oh, this is really amazing. I wanna play with this.

[Chick]

Well, THAT imgbox page gave me a bunch of virus popups that I had to ALT-CNTL-DEL to stop -- you know the kind that when you close a window it reopens itself forever.

odd , i see no advertising and no pop up windows

Linux users unite!

I need to play with this program. It seems super awesome... Can someone send me some extra time?

not time

but the code builds just fine on my OpenSUSE 13.2 install using gcc 4.8
read the Makefile !!!!
you can just build "gaseous-giganticus" and "earthlike"

[Robbie]

Oh it's not about whether or not I can pull off the build, it's whether or not I have time to do the build.

I started my Linux journey on opensuse! I'm on a pretty awesome custom built arch Linux now.

Very interesting stuff!

And welcome!

gaseous-giganticus.c is cool

been playing around with it for a bit

planet clouds are "fun"

Cool, glad to see someone other than me getting something out of it.

Been getting a little better at clouds, but still not quite as good as I'd like.

Procedure for how to make something like the above is described here:

Oh, also johnvanvliet, since you're actually using gaseous-giganticus, you may find this interesting. I ran the thing with various noise scales systematically, which oddly, I'd not really done properly before, and got a much better feel for how the velocity field looks at various scales. You can see here: http://smcameron.github.io/space-ner...ise-scale.html

Also, I noticed you seem to convert to equirectangular projection... don't you get weird artifacts at the poles? Perhaps some other software you're using requires an equirectangular projection? I originally began with equirectangular projections, but quickly moved to cubemaps because of the problems at the poles. Now, the cubemap layout that gaseous-giganticus outputs is probably non-standard, as I just made it up, though I don't know if there is anything like a standard for that sort of thing.

[johnvanvliet]

The software i use, uses Simple cylindrical
( but some software can use a cross CUBE map or a UV mapped cube faces )

For making a NormalMap from a DEM I use a custom tool for converting 16 bit DEM's to a normal map that CORRECTS for the poles so that the tangent Normalmap dose wrap around a Sphere and NOT a flat plain like most tools do .The program also can be used on HUGE MAPS!! ( 131072 x 65536 pixels -- 16 Gig )
-- crasy-bump dose NOT map to a sphere
-- PhotoShop dose not map to a sphere
-- the NVIDIA dds normalmap tools do not map to a sphere

Polar -"pinch" is a problem but a manageable one that can be fixed but care must be used .
things like DO NOT use Gaussian interpretation in remapping ( linear or nearest neighbor )



just started looking at the "earthlike" code to see if a easy hack can output a 16 bit or 32 bit heightmap instead of a normal map , but i can create a height map from a normal
but the earthlike NormalMap cubes have been a bit of a challenge
-- earthlike defaults except for my own input heightmap

( i introduced a error in the conversion above ,and have not yet redid it to FIX the error i added )

the HUGIN "Panotools" are what i use to move from cube to simplecylindrical and to a Cube map from simplecylindrical
and that handles 16 bit gray tiff's

Most of the time i am using gaseous-giganticus , as other software can output a decent "earth like" heightmap that i can then use as a base for coloring the land



have you had much luck in getting a good cratered planet , like Mercury or the Moon ( and rocky moons of Jupiter and Saturn)

something like this real Height data map of Ceres ( very EARLY map from last March )


PS. if you have seen the above Ceres HeightMap around , it is the map i posted back in March -- this one is the only one in the public
