Thanks, So you say that OSG is supposed to work the way I want. I suspected that EyePoint/ViewPoint methods could be somehow used for this purpose but it looks like one of them was exactly added for this purpose. Thanks for clarification. So now it seems that my ShadowMap derived code might have another problem. I will look into it and see what goes wrong.

Here are some related email threads: http://osgcvs.no-ip.com/osgarchiver/archives/August2006/0307.html http://lists.openscenegraph.org/htdig.cgi/osg-users-openscenegraph.org/2007- October/003697.html Eventually, Robert made some changes to OSG (including the addition of the View class) which eliminated this problem. It fixed my own shadows completely. I wonder if your shadows are just finding some corner case that is tricking Robert's fix into not working.... -- Terry Welsh - mogumbo 'at' gmail.com www.reallyslick.com | www.mogumbo.com > Message: 5 > Date: Tue, 26 Feb 2008 15:18:13 +0100 > From: "Wojciech Lewandowski" <[EMAIL PROTECTED]> > Subject: [osg-users] Problem to consider: Shadow maps and LOD > computation > To: <osg-users@lists.openscenegraph.org> > Message-ID: <[EMAIL PROTECTED]> > Content-Type: text/plain; charset="windows-1250" > > 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 plain wrong: LODs should be always selected based on distance from main camera. Is there a way to overcome this problem and force LODs drawn into shadow map to be base on distances from main cam ? > > Thanks in advance, any ideas would be appreciated, > > Wojtek Lewandowski _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
