There is a demo using current hardware texturing capabilities which implements
shadows using depthmaps but it doesn't perform the "percentage closer
filtering" of supersampled shadow maps devised by Reeves, Salesin & Cook. If
this is specifically what you are after then I don't know, sorry. Otherwise
check out the demo in:
/usr/people/4Dgifts/examples/grafix/realityengine/fastshadows/

Angus.
