Hi Adrian, I do not think that a nodekit just for this purpose is usefull or needed.
This kind of screen space algorithms can be perfectly described by the osgPPU. I really like this kind of effects and it seems that it is very straight forward to implement. I will try to create a .ppu file which can be easyly used with osgPPU to apply the SSAO onto your currently bounded camera (the same way as it is shown in the example of osgPPU for the blurring or hdr). The osgPPU will be released as developer/stable release soon, since I now get little bit more time to fight the last bugs away ;-) Best regards, Art --- "Adrian Egli OpenSceneGraph (3D)" <[EMAIL PROTECTED]> schrieb: > Hi Andreas, > > may you would be able to implement an opensource > nodekit for openscenegraph, > like osgShadow.
