Star Field Plasma Wallpaper

Plasma 4 Extensions

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!!

Thanks for making a video! BTW I like your desktop layout ;)

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!!!

So nice!! This preview show the powerfull of plasma!

I suggest you to use openGL. I will try to do something like that with GLUON.

I'm currently trying to port over to openGL, but it keeps crashing ;). Once I get that done it should be much better.

Good luck with your project :)

Thanks again! :) I very much appreciate package contributions, because most users probably don't have development files installed.

If you could add a space background, or user could do it, it would be amazing :D

Yeah :). One of the features I have planned for the next version is to have a image as a background.

This is really cool, but it pegs my CPU at 100% so I can't use it.

The current code can probably be made more efficient. In later versions I might use openGL instead (if its possible). Once the efficiency issues are resolved it might be ready for everyday use.

Hopefully if I can port it to openGL then it should drastically reduce the CPU Usage
