Hello, I'm using "scaled discs" mode to render stars, but even with bright textures they seem too dark for me. Is it possible to make them more luminous by change of any parameters? I found buildstardb.pl
file, but it contains infos about B-V factor mainly. Maybe any way?
There is a range of star brightness adjustment available via the "[" and "]" keys. I suppose you exploited that option already? (With some knowledge of the sources, it is VERY easy to increase that range)
Are you sure that you did correctly adjust your monitor? There is special software for that depending on your OS.
The scaled disc star model is a very bad approximation to account for the large range of star brightness on typically low-dynamics monitors. Eventually so-called "shader stars" should be implemented, as existing in form of a patch by ChrisL viewtopic.php?f=10&t=16031&start=0
or as a regular feature in my forthcoming celestia.Sci. viewtopic.php?f=3&t=16981&start=4
The "shader stars" combine a varying (OGL) pointsize with a (possible) Gaussian halo to increase the renderable range of brightness. Below a certain threshold brightness, stars have no halos. These sophisticated stars are implemented by means of the fast OGL shader technology. Hence the name.
After patching the sources, one needs to recompile, however. There are several discussions about these much better stars in this forum. See the first link and/or use the search engine.
