Does someone knows where to find some implementation examples (with source if possible) of image based renderign using OpenGL ??
Thanks in advance.

What do you mean by image based rendering??
Perhaps are you interested in volumetric texturing (Using 3D texture and viewpoint aligned slices or 2D textures and object aligned slices) ?
A way to render complex objects as textures on planes, interpolating just few shoots of the objects themselves.
For example I have a really complex real object, I take some shoots of it from (say) right, front, left and back.
Then interpolating theese images I can render the object from ANY POINT OF VIEW interpolating source images and using 'em as a texture.
That’s wat I ment, sorry for not being more precise.

I’ve got a pdf document about texture wrapping, I will send it to you.
If anyone want it, mail to me.
These sites both have IBR information and demos:

no need to apologize, shoould have known what you meant since i am using image based and geometriy based rendring, for the last few months 
The links provided by Tom are very helpful, thx.

Yes, I’ve already seen theese sites, but I can’t find an implementation with sources to look at.
I tought it was usefull not to “skew” images by software but rendering a rotated textured poly (qith the source images) adn then read back it to a texture to use on a cube.
It could be more fast than doing calculations by software. maybe
