Hi J-S,
Thank you Wojtek, I'll check that out! I'm really very grateful to you
for contributing this. I've been banging my head on this and we're still
on OSG 2.2 here so I didn't think of going to see in the new additions
if there was something that would help me out.
You're welcome. I
Hi J-S,
This is the part I'm having trouble with. I actually don't mind using
the scene bound I get with the ComputeBoundingBoxVisitor, but getting a
usable camera frustum (both for main and light cameras) and then
intersecting those is the hard part for me. Any tips there? How do you
create the

And thats it. Thank you Robert !

Hello Sebastian,
I'm quite confused regarding the osgShadow implementation.
My scene and my light-positions are static
to submit it around the end of March.

Hello Wojtek,
then I compute intersection of this convex scene hull with main camera
frustum and coarse light (shadow) camera frustum. This produces my
minimal scene bound polytope which I then use to further narrow shadow
camera projection.
This is the part I'm having trouble with. I

Hello Wojtek,
Actually most of the time was spent
on algorithms finding minimal shadowed scene bounds under OSG. It was a key
to good shadow mapping results.
Well, that's what I'm working on right now too! If you are planning on
contributing this sometime, would it be possible for you to
Hello Sebastian,
I'm quite confused regarding the osgShadow implementation.
My scene and my light-positions are static. My idea was to capture the
shadow-map only once
and apply it consecutively in all frames. I'm a bit lost where to start.
Neither update nor cull seems to be the right

Hello Wojtek,
ShadowMap::cull invokes culls traversal for both main camera
(ShadowReceiving) graph shadow camera (ShadowCasting) graphs. So if you
block whole cull on ShadowMap level - it won't draw the scene as well. The
trick is to block only the portion that culls ShadowCasting graph.
