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.

Changelog:

0.1, 0.2, 0.3
1 Faster skeleton animation function for fish. (this dropped CPU usage by half or more on my computer even with wave added. Matrix is only calculated once for each bone instead of once for each vertex)
2 Added ocean surface with waves. (Please let me know what you think)
3 Moved things around to make it more aesthetic

Please give feedback so I know if I'm going in the right direction

0.4
1. Changed time basted movement (much faster now)
2. Adding Setting Dialog.
3. Adding new fish

0.5
1 Changed form qmake to cmake.

0.6
1 Added rocking motion.

0.7
1. Bug fixes and performance improvements.
2. Added Orca.
3. Added new function for attached fish (remora).

0.8
1. Bug fixes (fish disapeare after screen suspend)
2 Added fish: Grouper.

Some more "stuff" on the bottom ( plants, corals, rocks ) that the fish could swim around would be great.

Also, the chest looks very solid and "in your face". I would expect it to look a bit softer being under water. Perhaps just moving it backs a bit would help.

Thanks for the idea. You any good with a 3D modeler like blender? If so, would you be willing to help out with that? Not to put you on the spot but anyone is welcome to help. I will add your name to the list of credits. Just let me know. That goes for anyone who would like to help and contributes.

No, to be honest I don't know the first thing about 3D modeling. Also, I simply don't have much time to spend on other projects as I am quite deeply involved in Amarok 2.

I hope other people will joining you though, and I am sure they will as this projects seems to have so much potential.

And it runs slow. Edit Ocean.cpp line 34
Ocean::Ocean(QWidget parent) : QGLWidget(QGLFormat(QGL::SampleBuffers|QGL::AlphaChannel|QGL::DirectRendering), parent)

to look like

Ocean::Ocean(QWidget parent) : QGLWidget(parent)

Will speed thins up for you.

Great work. It still has some rough edges, but with some work, this could turn into something really fantastic!

I am already looking forwards to future versions! :-)

How about donating cycles?

I understand that this is only a screensaver, not really an "Ocean Saver" per se, but it would be nice if part of the config for this screensaver could somehow tie into donating spare CPU cycles to (in this case) an ocean-related research group.

Just a thought :)

Good question. Sorry I did not explain this before.

1 download.
2 extract (tar -xzf "the file you downloaded")
3 change to the new directory (KOceanSaver)
4 run "qmake KOceanSaver.pro"
5 run "sudo make install"

That should do it.

Let me know if it works ok for you. Hope you enjoy it.

Cool that would be grate. There are some pictures of fish in the data directory. Make low polygon models of the ones you like and let me know. Don't make the fins one sided They have to have two sides. My e-mail is down so just let me know when you get something with a comment. I will try to get my e-mail up soon.

Thanks a lot for your help.
