Hello Jim,
ShadowMap does suffer from bad aliasing when the viewpoint is very
near the shadow.
The Orange book (GLSL shader) describes how to super-sample
the depth buffer to mitigate aliasing.
Indeed, aliasing is a big problem with vanilla shadow mapping in
almost all real-world cases.

Hello Dan,
I'm looking at shadow techniques provided by the osgshadow nodekit for use
in a production project. On the wiki it reads like only ShadowMap is production
ready and all the others have problems. Is this the case? Or have the others
been marked as experimental because they do not

Hello Adrian,
Parallel Split Shadow Map: it's still under *beta* release :-) i wait
for a review by a specialist, ... please review, test this algorithme,
for terrain, ... it's once of the most robust algorithm, but it has to
be tested.
I knew any talk about PSSM would get a reply from you

No, i have no problem with the PSSM and all of the discussion about it. but
i would like to pass the pssm through a review, because i am not computer
graphics specialist, i am more computer vision guy. :-) this is the only
raison why i am answering all of the emails people asking for enhanced
