[osg-users] SSAO : Screen Space Ambient Occlusion

[Adrian Egli OpenSceneGraph (3D)]

Hi Andreas,

may you would be able to implement an opensource nodekit for openscenegraph,
like osgShadow. This would be greate to get, implementing twice similar
things are not so funny. if you would be able to add Inigo algorithm this
would be really greate.
