[osg-users] Are there any good effects libraries that can be integrated into OSG?

[OpenSceneGraph Users]

I don't know of any good general effects libraries, basically the problem 
with this type of stuff it tends to be pretty specialized for your 
rendering pipeline, and OSG allows a lot flexibility with setting up 
rendering pipelines, making one size fits all solutions for something like 
SSAO to be tough. 

I strongly suspect rolling your own solution for a lot of the effects is 
going to be the easier way of going.  I would look at the osgdeferred 
example, which is good to show you how to do multiple passes, which is key 
for most of these effects:

For SSAO, you want to setup a rendering pipeline like:
Forward Depth Pass->A SSAO pass ->Blur Pass ->Lighting Pass
A basic  tutorial on SSAO:

For shadows, OSG does have osg::shadows, which works......but if you have a 
larger scene, and have a more complicated pipeline....you are likely better 
off creating your own, which basically involves a depth pass from your 
lights perspective, then your forward lighting pass.
