Extended PSM (XPSM) (http://xpsm.org) provides practical solution for real time shadows rendering. Distinguishing features of this method from other shadow map reparameterization techniques is:
* high quality shadows, based on suboptimal projective space parameterization
* complete artifact reduction with correct post perspective space Z bias
* stability, free from singularities
* easy integration into any shadow map based engine
* patent clearance
