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.
