[osg-users] Deferred shading + normal mapping + shadow mapping?

[Christian Buchner]

Hi,

I've just submitted a related code sample to osg-submissions. It currently
does bump mapping and soft shadows.

Things to improve are:
  - this needs to support more light sources (not necessarily for shadowing
though)
  - it needs better material handling (support for emissive colors,
reflective surfaces, gloss maps...)
