Hello @all,

i am work on some ideas for an 3d space game..at this point its about the stars background.

(its not a problem to create a starfield jpg with gimp2), more the problem is.. the background

is dynamicly created when entering the system/orbit of an planet.. but how to

handle the background in 3d..




at moment i create 6 face in FBO Textures with view angle of 90 (rendered each with same scenario,but different view angels)

and put them in a skybox

and i always still see the edges of the skybox..is there any other method i can use?




do you have a hint/link for an good page about rendering planets/athomsperic effects etc?

(at the end the planets surfaces/clouds is created dynamicly..to get a giant amount a different planets)




anybody remember StarGilder2 in the 1988




much thanks

here a small picture of the problem and what i do..




i render the same scene to 6 fbo textures (changing camera angel) and the camera got an view range of 90 degrees

the stars are pointsprites (with a little alpha color..the more of them overlapping the more the "blue" color becomes visible)

the pointspite work a following... the matrix is rotated around the camera so that the pointsprites always facing the camera

when rendered into the fbo




in this picture you see the connection of 3 fbo textures..you see that the rendering of the stars fit...but i see the edge of the box...hard to describe

Yeah you can definitely see the seams there. Some stuff to try:

- are you sure all sides are tiled perfectly?
- is there no lighting at all on the cube surfaces?

Here's some free skybox cubemap textures you might try:

Maybe see if you can still see the cube corners with those textures.The edges of the textures need to be specially distorted around the cube edges. Try googling for a Cube Map Generator that works on your dev platform.

i try the textures tomorrow (need some sleep)




but at the first look of the texture i see something intressting... the pointsprites in mein demo always facing the camera...

in the cubemap textures they do not...
