Re: [osg-users] [vtp] Segfault in VTP, but looks like OSG

Rick, Is the problem specific to your exact platform? glutSimple runs fine elsewhere, including the Windows and Ubuntu boxes here. The most likely explanation is that you have two copies of OSG on your system, compiling against the headers of one, linking against the other. -Ben

Re: [osg-users] ShadowMap uses wrong mask for traversal

to be set. Yes, and that logic is preserved by the fix i proposed. I'm know you're very busy, but really this is a simple 1-line fix, applying the fix would keep users with non-default traversalMask from having to fork the OSG code in order to draw shadows. -Ben __

Re: [osg-users] ShadowMap uses wrong mask for traversal

same pattern as getCastsShadowTraversalMask. As you can see in the example case i presented, this is not the case. Nor should it be the case, because if they have bits in common, then there is a conflict. -Ben ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] ShadowMap uses wrong mask for traversal

ore powerful visitor capability in OSG that would save the day here? -Ben ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] ShadowMap is wiping out ambient light; how to fix?

ShadowMap can use that light with black ambient, and leave the real light alone. But, this is messy; we don't actually want 2 lights turned on in the OpenGL pipeline, and we'd have to constantly copy values (like direction) from the real light to the dummy light. -Ben _

Re: [osg-users] osgShadow, node traversal, and node mask

ing a shadow, because the algorithm can't do both. Try replacing your ShadowTexture with a ShadowMap and see if the behavior changes; ShadowMap does support self-shadowing. -Ben > - > From: Alejandro Segovia [EMAIL PROTECTED] > Sent: Thursday, May 15, 2008 8:20 AM > > I&
