If someone could make an application where you design a seamless skybox that would be great, terragen cant be used for spacescapes and spherical spacescapes are very troublesome to get working and are lower resolution than 6 seperate skybox textures.

It would need the ability to apply some noise across the seams of the six textures, dont know how that would be done though.

To my knowledge Tattoo hasnt got noise filters,blur filters, etc.

The best way of doing it would be to use 1 picture of a spacescape and cut out 6 textures from it (automatically) if that is possible.

...But uses only one surface instead of six :)

As someone said before you need to apply the texture to a sphere, use a geosphere (assembled like a football, all tris have the same size) and then take 6 pictures from the center of it. all you need to do is adjusting the zoom of the camera, once for all, so it will tile seamlessy.

I think Fredborg or someone else started work on a skybox generator.. have a look in Gile[s] forums.


Dreamora(Posted 2004) [#5]
or buy the one at tgc *hahaha*

I did a quick few test, but haven't got time to finish it now. There are two different versions:

http://www.frecle.net/giles/download/SkyDemo.zip (better)

I'm working on it
A B3D app could create skydome and skybox

How do you set the 6 angles to take a picture from?
If it is textured to a sphere to begin with the distortions at the poles will be in the pictures surely?

There is a app called "skypaint" that does what you ask for!


Pongo(Posted 2004) [#10]
Save this as "filename.tgs" You can then run it from within Terragen to create six images for a cubemap/skydome

Creates a perfectly seamless skydome

; This script automates the process of outputting images
; which can be composited into a cubic panorama image, to
; be used to make a cubic QTVR movie or as an environment
; map. Of course you can also use this for cylindrical panos
; by only using the first 4 images rendered or deleting the
; last two sets of script commands from this file.
;
; IMPORTANT : Make sure the image is square and uncheck both
; the "Fixed height above surface" checkboxes in the Rendering
; Control window. 
;
; In case it isn't obvious, the fifth image goes at the top
; of the first image, and the sixth image goes at the bottom
; of the first image.

Is an interestnig site. Would be nice to see something like this in real time for cloud generation.


JoshK(Posted 2004) [#12]
Terragen can be used to make skybox. Look for a script called "terrasky".


Pongo(Posted 2004) [#13]
erm,... or run the script I posted above. ^^^ (creates a seamless skybox from terragen by making six views that can be mapped.


slenkar(Posted 2004) [#14]
Im looking for a spacescape though, e.g. a custom made picture made into a 360 view.
Custom made picture consisting of stars,nebulas only,
no ground, no clouds.

You might still want to try this one: http://www.frecle.net/giles/download/SkyDemo.zip


slenkar(Posted 2004) [#16]
yeh thats o.k. there is a little distortion at the poles but not too much, but there seems to be no way of designing your own spacescape (and it has DEMO all over it)
