FBO and multisampling
Author
is it possible to have multismapling/antialaising when rendering to an FBO?
if so how?
Well, NVidia has one solution (it's one extension), but I don't know its name. ATI hasn't got anyone (I have ATI card at home, so...).
Another way is to write your own antialiasing. Supersampling, multisampling or another type, try search google - there are many things on this topic (how multisampling works, how supersampling works, etc.). All is done in postprocess.
On NVidia antialiasing topic - there http://developer.download.nvidia.com/SDK/10/opengl/samples.html the second demo FroggyAA is using FBOs and MSAA.

yes with nvidia u need ~100+ drivers
+ in your code instead of
glRenderbufferStorageEXT
use
glRenderbufferStorageMultisampleEXT

use
glRenderbufferStorageMultisampleEXT
