It's not so much that the OSG code is out-of-date, more that a range of
different approaches to doing shadows, which approach works best is very
data/application specific so general purpose shadow code that osgShadow
provide can fall short, simply because it doesn't know what going to be
best for you scenes.  It's also a bit out-of-date too though :-)

For some scene types you might well find that one of osgShadow
ShadowTechnique implementations does actually work well for your scenes, if
so, great go an use it.

However, I would recommended learning about shadowing can be done in modern
hardware and modern extensions.  Then see what approaches might provide the
best visual quality/perfornance for your datasets.   Most modern
applications will also be writing your own shaders, so shadows is something
would fit within this well.   It does require more knowledge but the
results have the potential for being better.

Robert.
