Star Field Plasma Wallpaper

Minimum required   KDE 4.x
Downloads:  2245
Submitted:  May 31 2009
Updated:  Jan 20 2013

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!!

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

Thanks for the package!

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

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.

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.

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

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 :)

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.
