Description:

A very nice screen saver of the the cosmos, complete with an infinite field of stars whizzing past your screen as rotating planets, asteroids and space ships randomly appear against multicolored galaxies off in the distance. Installation is very simple works great for all X11 with QT4 installed. I will try to build some pre-compiled packages when I get time.

"Floating point exception"

I am getting this more often than not. Running KDE 3.5, Qt 4.3.3, QMake 2.01a

Also, how do I set it up as a screen saver in KDE? I ran qcosmos -setup and and got a setup screen to enter parameters, but it don't show up in KDE screen saver list

Very nice app otherwise. :)

I found out that qstars (and thus qcosmos) can be easily customized: just drop any planet texture in the planet folder, and the screen saver will draw it. In addition, the size of the planets appearing on the screensaver depends on the size of the textures. Taking advantage of this, I heavily modified it and now I have about 60 planet and star textures of various sizes.

So, by the way, why don't you try to improve qcosmos since you went through the trouble to make it for qt4? I could post you my textures, but I don't know/remember all the sources and some might be copyrighted. However, here's a good place to start:
http://simsolsys.com/
It includes links of it's sources. Also don't forget to use Celestial textures.

It would also be nice if you could program some other improvements, like drawing shadows on the planets or changing the camera angle. It's truly a very nice screensaver, but it can become even better.

Just a few ideas.

Now that I looked a little more into this... it seems that qcosmos looks suspiciously like the much older qstar screensaver, also available here (which I managed to install, since I found an rpm package for it). If your work is based on this, which looks certain, you should mention it. In addition, people would like to know what you've modified.

Hi there, you are correct it's a port from Qstars. I did mention that and give full credit in the documentation... But just to be clear. This was forked from QStars 0.4, (at the request of the author of QStars) and is merely a port from QT3 to QT4 libraries. There has also been some small changes in regards to the centering of some of the objects for very large desktop resolutions but other than that it is essentially the same.

You probable need the QT devel packages to obtain qmake.

...I was looking for a screensaver like this. Unfortunately it seems that my terminal doesn't recognise the qmake command, even though I have qt4 installed. Anyway, I'll be patient until you make an rpm package.
