    v1 v1  
     1This example program demonstrates the use of several shadow techniques that are available in osg or that are currently under development. 
     2 
     3=== Volumetric shadowing ===  
     4Not fully implemented yet 
     5=== Shadow mapping === 
     6Standard depth shadow mapping 
     7=== Soft shadow maps === 
     8Needs shader model 3.0+ support. 
     9=== Parallel split shadow maps === 
     10Currently under development
