Description:

This plasma wallpaper draws an animated starfield in the background of your
desktop. It was inspired by the star field chrome experiment -
www.chromeexperiments.com/detail/starfield/

INSTALLATION
------------
Firstly make sure you have the KDE workspace development files installed. For ubuntu run: sudo apt-get install kdebase-workspace-dev

If the source came in a zip then unzip it first. To install run install.sh:
Open up a terminal, navigate to the the starfield directory which has
install.sh then type:

./install.sh

You may be asked for your root password during installation.

After installing log out and then log back in. Then right click on your
desktop, go to 'Desktop Settings'. Then in wallpaper type you should see
'Star Field'.

CONTROLS
--------
- Dragging the starfield with the left mouse button will change it position
- Middle clicking on the wallpaper will pause the animation
- Mouse wheel scrolling will change the perspective of the view.

CPU USAGE
---------
This wallpaper can be quite CPU intensive. To reduce the CPU usage you may try
the following:
- Pause the wallpaper. This should make the wallpaper use 0% CPU
- Enable 'Pause when desktop loses focus' in the advanced options
- Reduce the frames per second. This is THE main factor in deciding the CPU
usage. 15 FPS gives a somewhat smooth animation.
- Reduce number of stars
- Use a blank background (Leave the background path empty)
- Reduce trail length
- Use a lower quality
- Turn off antialiasing
- Use plasma in raster mode. To do this first quit plasma then restart it with
-graphicssystem raster argument:
For KDE 4.2:
kquitapp plasma
plasma -graphicssystem raster

For KDE 4.3:
kquitapp plasma-desktop
plasma -graphicssystem raster

However be warned that this method has not been thoroughly tested.

NOTE: Star speed does not affect CPU usage.


ENJOY!!

cool! I'm using it with Yuri_Planet background.
Only if it was a bit less cpu-consuming ... even on rather low detail it takes my dualcore 3,2GHz at about 30% when "idle" ...

Keep it on :-)

In the next version I'm hoping to add the ability to pause the animation. That way when it not visible or you don't need it to be animated, it won't eat up your CPU :).

Funny - yesterday I was just thinking about proposing the same idea ...
Would be great if you implemented this function soon!
Thx for your efforts!!!

In my PC Athlon64 3800, nvidia 6200, 1GB RAM can not be used, the whole system slow.
In Laptop Core 2 Duo 2.4GHz, NVIDIA 8600M, 4GB RAM, runs stable, but considerably consume resources.

Yes this wallpaper is very resource consuming :). I recommend leaving it in paused mode most of the time.

In the next version I'm thinking of adding the ability to pause the wallpaper automatically when there are windows open or a window is maximised.

The reason why it uses so much resources is because it uses software rendering. Using hardware accelerated drawing like openGL would considerably reduce resource usage.

So far I have not been able to successfully use direct openGL rendering. If anyone out there can help me it will be very much appreciated :D.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
