I am working on my space simulator program myself. I now found good useful algorithm information about procedural star rendering in GLSL programming that Seed of Andromeda game and Space Engine simulator use that similar technique for. I googled and found a copy of open-source Seed of Andromeda package on GitHub has some example programs for that.

Does anyone have good alternative technique for procedural star rendering in GLSL programming?

Thanks,
Tim

I removed a link because it automatically added link without my knowledge after I clicked post button.. Thanks for let me know that.

@sword7 why are you looking for alternatives?

what you have found is good and is in glsl.

is there anything you don't like or understand in it?

@LorenzoGatti Yes view anywhere from one point to closeup like in Gaiasky, Celestia and Space Engine. I am figuring some routines in Seed of Andromeda source codes as well as in Celestia/Gaiasky source codes. For one point stars, just render as a pixel. When getting closer to star, switching to sphere rendering when checking star size is more than one pixel.

@ddlox I was searching for more but one good article for in GLSL programming is now enough good.
