Cull callback as part of light perspective

[Anders Backman]

Is there anyway of understanding that when you get a cull callback as part of rendering the shadowmap from the lights perspective?

I am trying to set some LOD for when the light viewpoint is being rendered compared to the main camera perspective.

Hi Anders,

It's quite a few years since I worked on osgShadow so rather rusty.  From what I recall it's possible to set a viewpoint for controlling the LOD levels so that within a shader rendering pass the same LODs are used as for the main rendering pass.  Does this sound like what you are after?  I don't recall how to set it though, hopefully this will be enough to point you in the right direction.  Look at osg::Camera/osg::View./osg::LOD and osgShadow to see implementations to see if there what the exact mechanism is and how to control it.  

Cheers,

Robert.
