Hello everyone,
I have following problem: Shadow Mapping - so called duelling frusta case ie
light direction opposite to view direction. Objects drawn into Shadow Map also
contain LOD nodes. When rendering shadow map LODs are drawn based on distance
computed from shadow camera. But this is
Hi Wojtek,

plain wrong: LODs should be always selected based on distance from main
camera.
Oh, nice problem there... It's probably just an oversight, and the fact

Hi Paul,
Ideally, you would want the shadow caster's LOD to be selected based on
the
distance between the eyepoint and the shadow receiver, wouldn't you?
Actually I would like it to be based on the distance from eyepoint to Shadow
Caster (measured in main camera view space). If its based on

Hi Brian,
It looks like you'll need to create a custom cull visitor that stores the
desired eye point and overrides the CullVisitor::getViewPoint method to
return the stored eye point instead of the CullStack view point.
Thats sounds like it something I might be able to do ;-). Do you know if
