[osg-users] How to document osgShadow?

[Adrian Egli OpenSceneGraph (3D)]

Hi all,

there are still some other issues in pssm implementations.
i got this morning an email from david roger and we decided to check the
pssm algorithm with latest svn, hopely we can find the bugs.

may others can review the code, then we can retest it
