I was wondering if anyone knew of a simple opengl game engine for linux where the source is available to read.
I basically want to read the source to get a better idea of how things are put together without worrying about the code being cross platform or having fancy particle effects or anything.

Have a look at DevMaster, a website with a lot of information about game programming and a 3D Engines Database.

SDL supports OpenGL, is open source, and you can port your game to Windows if you want. I've used it to write a Tetris program. It supports C and C++.
A simple engine for beginners, written in C++, contains samples to start with and sample game project to study:

I'm new in C++ and looking for a way to create gui just like windowbuilder under eclipse (java).
I will appreciate if someone can help me to find tool like windowbuilder.
OS : Linux
Thank you
Personally I'm a fan of Qt.
However, it depends entirely on what you want to do. Qt is primarily for cross platform development, so it'll look and act mostly the same between any platform, it also has a large library that may require a bit of a learning curve at first - but the licencing options make it look pretty. Also the documentation is very awesome.
There are of course a lot of other options like:
GTKmm (based on GTK+), wxWidgets, FLTK, etc...
Also this is a duplicate question, so look at some of these other answers:
How do I create a GUI for a windows application using C++?
How do I build a GUI in C++?

I'm looking for a sample code.
It's 3D modeling using camera.
like this: http://mi.eng.cam.ac.uk/~qp202/my_papers/BMVC09/
Hopefully, I want to use c or c++.
Thanks.
openCv is probably the easiest place to start.
There are a few chapters about creatign scenes from stereo pairs (which is a bit easier) in the opencv book otherwise 3d models from image understanding is still possible - but a lot harder mathematically.
You may want to check out OpenCV for computer vision functionality and OpenGL for 3D graphics. Both are widely used APIs with plenty of online documentation and examples, both official and third-party.
You could try contacting the author of the paper to see if he's willing to release his source code to you. It looks like he used CGAL (for the Delauny Tetrahedralisation) so if you go that route, you'll need to get a copy of that.

later this year I'm going to have a lot of time on my hands, and I thought I'd start a "small" project for myself and release it as open source.
I'd like to code my own Fraps alternative. (or continue with Taksi http://taksi.sourceforge.net ).
Fraps is a video & sound recording programm, which captures the screen during gameplay. It has way more functions than I need and its commercial.
All I want is being able to record the screen / game I'm currently playing continuously including sound no other extras.
Now this is a new area for me, but not the programming languages. I thought I'll be using C++ (& others if needed).
What I need are hints where to look, and what to look for, where to read stuff rearding it. Etc. etc.
I hope y'all can help me!
Here is some good info on the techniques used by FRAPS.

My company published a source code in C++ for hooking into DirectX to capture video and calculate FPS (audio is not included). It is available on github as AVRecorderTool.

On DevMaster.net I found only RealmForge. Is this the only choice? Are C/C++ game engines suitable for D? If yes, what difficulties I need to overcome to work with them?
D supports calling C functions directly, so you could use a C engine, though you'd have to convert the header to D to allow interfacing. This can be somewhat automated with the htod utility. If you want an engine written in D, you can look on dsource, though I don't know if any of these are actually usable right now.
I think OGRE has D bindings http://www.ogre3d.org/
I know OpenMW is using Ogre and D http://openmw.sourceforge.net/jaws/

(Yet Another Game Engine) is an open source, cross-platform, and free 3D game engine. It is currently in the early stages of development but is planned to incorporate many features of leading commercial game engines when finished.

The current version of libsdl (1.2.x branch) is very, very slow with blending and per pixel alpha (as it uses software blending). Is there any other good alternative to it?
SFML is exactly what you need: http://sfml-dev.org/.
Skim through the tutorials, you'll see that it's way easier and more powerful than SDL.
There is SFML : http://www.sfml-dev.org/
Or... just use OpenGL on top of SDL.
GLFW. It only tries to do one thing (window creation/input handling). It is C based and pretty easy to use provides bindings for several languages.
SFML does all that and also provides an API for audio, fonts, and networking. It's nativity a C++ API but provides bindings for several languages.
There are other thousands of options: SDL (older), Unity and UDK if you want to create a game, ...
