Description:

An under water screen saver for KDE4
Thanks to John Stamp for your help.

todo:
sea creature swimming pattern
camera movement (swimming through seen)

How to Install:
1 install package build-essential cmake kdebase-workspace-dev libqt4-opengl-dev or your distros equivalent
2 download.
3 extract (tar -xzf "the file you downloaded")
4 change to the new directory (KOceanSaver)
5 cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr CMakeLists.txt
6 sudo make install

And a big thanks to the guys and gals at mepis-deb.org for making the debian packages for all of us who use a debian distro.

If your distro is not (k)ubuntu then you may or may not need the -DCMAKE_INSTALL_PREFIX:PATH=/usr. a simple
1 cmake CMakeLists.txt
2 sudo make install
will work for you.

Would it be possible to convert this wonderful screensaver to an xscreensaver module (as Plasma 5 doen't support/provide kscreensavers anymore)?

At the conclusion of final compilation, you suggested to run kbuildsycoca4
here are the final Terminal lines:
-- Up-to-date: /usr/local/share/kde4/services/ScreenSavers/koceansaver.desktop
-- Up-to-date: /usr/local/share/man/man1/koceansaver.kss.1
bumpy@bumpyputer:~/Downloads/KOceanSaver$ kbuildsycoca4
kbuildsycoca4 running...

nothing happens after that, & koceansaver.desktop is not listed in the OpenGL screensavers.
How can I fix that?

I got that solved, but since then have updated to kubuntu 12.10 & your wonderful screensaver is working fine.. except for one thing: what do I have to change to keep KOceanSaver running for a specified time length?
Also would like to know the file settings location.
Like every other fan, any hopes of more fish etc?
Big Thanks again for your magnificent screensaver!!

I love this screensaver! Please, can you also make an aquarium screensaver or add an aquarium mode?

Or maybe you could add the option to use an own background picture that is slightly (according to the settings on the graphic tab) covered by the waves and "fog" and color. I'd love to have a background that is not so monochrome: e.g. beige sandy gravel at the bottom, something more dark in the background, some green water plants, some more rock formations or corals.

And maybe some additional small fishes with a little more color ;).

I would love to. but I don't have the time. I was going to work on a better background but I think camera movement is what I'm going to do next.

Hi
this is a GREAT screensaver. I installed it on Kubuntu Oneric.
I noticed a "to do" about "swimming through the scene".
I don't know how hard that would be to do, but an idea I had that "might" be easier would be to have an option to where it is like one is swimming and just "hanging" in the water and kind of "moving up and down a little" with the underwater wave action. Don't know, just a though, but it is a great screensaver.

Well it is done. I fell bad because I did this so quick and someone else has ask for a remora attached to the shark. I have had no success. But your idea looks good. Thanks
