Re: [osg-users] Shdows Problem o vista
Hi Danny, does anybody has any idea on that issiue? We've used both osgShadow::ShadowMap and the newer osgShadow::LightSpacePerspectiveShadowMap (and variants) on XP, Vista and Linux without any problems such as what you describe. The only thing I can think of is if you don't have recent video drivers (or even if they are recent, perhaps there's a driver bug) on your Vista machine. You can try updating them. Other than that, it should work fine. Though I note you're setting the shadow map resolution at 4096^2, have you tried reducing that? I can't see a reason why it would cause a problem on Vista but not on XP, but... And BTW, using osgShadow::LightSpacePerspectiveShadowMap will allow you to use a smaller shadow map while avoiding shadow aliasing. Sorry I can't help more, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Shdows Problem o vista
Hi, I'm using Visual Studio 2008 with osg 2.8.1. I have vary strange problem with with shadows on my scene. On vista all shadows are moved chaoticaly (see attached pictures ). However on XP everything is OK and I can see my shadows casted by camera lights. I'm using the following code: const int ShadowTraversalMask = 0x2; osg::ref_ptrosgShadow::ShadowedScene shadowedScene = new osgShadow::ShadowedScene; shadowedScene-setReceivesShadowTraversalMask(ShadowTraversalMask); shadowedScene-setCastsShadowTraversalMask(ShadowTraversalMask); osg::ref_ptrosgShadow::ShadowMap sm = new osgShadow::ShadowMap; shadowedScene-setShadowTechnique(sm.get()); int mapres = 4096; sm-setTextureSize(osg::Vec2s(mapres,mapres)); node-setNodeMask(ShadowTraversalMask); shadowedScene-addChild(node); How can I solve this problem on Vista Thank you!
