Hi all,

I'm sort of a GEM n00b but have the basic understanding down. For a project I'm working on it would be wonderful to have an effect that simulates depth of field (blurry foreground, focused background and vice versa).

From what I've read about GEM through tutorials and google searches,

there's no simple object to do this. The best explanation I've found so far is http://glprogramming.com/red/chapter10.html (search for dof.c) which provides c code for producing this effect using the accumulation buffer.

Now I'm pretty determined to get this to work. As I see it, my strategies for now could be a) have someone else tell there is already a simple object/patch that does this b) try to build a patch that can mimic the code c) use the c code from that example to build an external that does this or d) try and fake it some other way (manually blur images or something).

I'm leaning toward c since I think it could probably be used by others in the future. I've never done openGL programming and my skills in building externals aren't great but this seems worthwhile to do for myself and probably others who might use the effect.

Thoughts? Help? Strategies?

Cheers,
