hello,

you can also try to render into a frambuffer with size 2n+1.
rendering this texture should performe a simple AA.

You could try a shader that does edge detection and above a certain threshold 
apply a simple blur.  That should give some sort of AA.  A more complex version 
could adjust the blur based on how strong the edge is.

I would like to get the render (started with only geos) from the
[gemframebuffer] anti-aliased. And I was wondering if someone has worked
on a shader to get this effect and if this person would like to share
his shader or to help in development ?
Thanx.

You could try a shader that does edge detection and above a certain
threshold apply a simple blur.  That should give some sort of AA.  A more
complex version could adjust the blur based on how strong the edge is.
