Hi Guys. I'm new to this forum.

I hope you can help me whit a very big problem I've got.

The fact is that I really need to implement a SSAO algorithm like the one described in the topic "A Simple and Practical Approach to SSAO"
found here in my XNA 3.1 deferred rendering engine (built from Catalin Zima's tutorial), but I just can't figure out how to do it.

I'm just wondering if someone cuold please explain it clearly to me or (if he's got it) send me a sample with something similar.
I've chosen the implementation described on this forum because it's really much better than the Crysis one which can be found on the XNA Community
(I've also tried implementing that one but with no results).

Please help me. I've looked all over the internet but couldn't find anything.

Thanks in advance.

What have you tried and which part of that are you having trouble with?

I've tried setting up the SSAO from this site first. But I couldn't get it working.
However I would much more prefer to implement the ambient occlusion described in this forum (the one I've linked in the first post).

The fact is that I'm not really sure of the process I have to follow to set up SSAO in a deferred renderer.

The document you linked in your first post explains this in detail.

Yes I know.
The problem is that I'm still a novice at programming. That's why I would really
appreciate some more explanations, especially related to a possible
implementation into Catalin Zima's example.
