[osg-users] Parallel Split Shadow Map (Update)

[Adrian Egli OpenSceneGraph (3D)]

Hi all again,

now i came from ATI X1600M test, same artifact as you described, small
shadowed line. i will try to figure out where it comes from. i guess we have
to set another polygonoffset. 0.5,0.5 is may not as good as it seams to be.
may -0.5,-0.5 or -1.0,-1.0 will work for ATI and NVidia. please check this
with the option
for polygonoffset and tell me what is a good offset.

thanks adrian
