Spacey Skyboxes from high-res NASA Solar photography

Post by The Yak » 07 Jul 2013, 23:47

So what happens when you take NASA high-res imagery, distort by polar coordinates, and turn it into a skybox? Well something along the lines of this...
Image

That's from an image taken from NASA's Solar Dynamics Observatory (http://sdo.gsfc.nasa.gov/data/), which is a gallery of regularly updated photos of the sun taken at different frequencies of the electromagnetic spectrum... cool stuff.

100% filter free baby, only polar coordinate re-mapping so it can be made into a six sided cube :-)

How did you do the polar coordinate distortion? I made a skybox from some NASA Eta Carinae nebula images and the distortion always bothered me.

In GIMP I just used the Polar Coordinates dialog, circle depth 100%, 0 offset, checked Map from top, uncheck To Polar, and from a spherical sun ending up with something like:

There's always going to be some distortion transforming an image like that, but it makes it very easy to just import into Cube The Sphere and split it into 6 seperate images, and then just re-assemble in ATI Cubemapgen.

I wanted to see one ingame...download...copypaste into map...suddendly armageddon! So I had to add a new picture to my interblog.
Looks very impressive ingame..

Also nice how one .sdd is 24MB but zipped it is only 4MB. Or still a bit big maybe for something that is only visible when looking up?
Oh and mirror to springfiles?

could you later move this to the resources area? that would make it more readily available to people

added a few more to the first post, pack now available on Springfiles

Not necessarily only visible when looking up, but also around edges of map, even more visible if there is /voidwater used like with the asteroid maps. More commonly, good reflective water/bumpwater settings should noticably the reflect the sky.

ah yes it can reflect in water.
But around the map I can not see skybox? Unless there is reflective water of course.
Or maybe the maps I tried do not have a skybox with a "bottom" or is it some map setting?

You mean if it's a dry map? Yeah, as long as water isn't visible and /waterplanecolor isn't used bottoms of skyboxes should show up fine.

Granted, this is where the downside of my method is apparent, the bottoms of the skyboxes are distorted more then other parts.

VRgrid map edge extension works well with these skyboxen.

I had already added the thread to resources page on wiki:
http://springrts.com/mediawiki/index.ph ... ldid=26921
There is no need to move threads to this forum to archive them, because there is such resource collection page.
Now nobody (except moderators) can comment on the thread anymore and give feedback or ask question. Not even Yak himself.
...

All that was discussed before:
