Hi everybody
i search 3D algorythms to make a 3Dmodeler and a simply 3D scanner.
do anybody know where i can found it?

There is a lot of algorythms about it. Please specify what are you
looking for?
You can find a little about it within documentation for POV 3.5
Just follow right links on top bar:
http://www.povray.org/working-docs/id000107.html#4_2
What you mean: 3D scanner ?

whow i dont speak english very well but i will:
i want to make a 3Dmodeler which make meshes so i search algorythms to
smooth meshes, make booleans operations, fill meshe's hole.
and for the scanner i must find algo to join two meshes correctly.

thank you
> What you mean: 3D scanner ?
i've used a projector to project ray on the object to scan and i take a
photograph of it.
i've programing a soft which create meshe from this picture (it's not yet
automatic) but this software cant join two meshes and haven't opengl
preview. I'm working on this last point but i can't find how i can do this!
You can see exemple on my scanner website: http://3dsman.free.fr/freescan3D/

Launch your favorites search engine and search for "image based
rendering." There are various methods to reconstruct 3D geometry from
photograph of an object or scene.

Here's some advice:
1. Go to http://graphics.stanford.edu/ and check their publications,
there has been quite a lot of work done on geometry reconstruction
2. Go to http://www.siggraph.org/ and check there.
3. You might have some luck on the ASME or IEEE websites, www.asme.org
and www.ieee.org
4. Lastly, if you're having problems posting in English, there is a
newsgroup on this server called povray.international (it was launched
a few days ago so you might need to refresh your groups list). Post
your question in French there, just indicate that in the subject line
like this:
Subject: [fr] I search 3D algorithms
I hope this information will give you some starting point.

my mesh is already made! i just want to join two meshes in one.

but what do you mean by that ? can't you just join data structures ?

You mean like pasting an arm on Venus of Milo?
Well, the points I made are still valid, Stanford, MIT and SIGGRAPH
are your best bet as far as I can tell. Unfortunately, this is not my
field by far so I can't really recommend authors or papers, but I'm
sure that with the proper keywords you'll find what you need.
