New Revision: 1866

Added:
   trunk/Engine/Shadows/NoDirect.cc
   trunk/Engine/Shadows/NoDirect.h
Modified:
   trunk/Engine/Shadows/CMakeLists.txt
Log:
Added a shadow algorithm that produces no direct light.  This is useful for
getting only the ambient contribution, although it might be useful to create
a more efficient method at some point.
