[osg-users] osgShadow and osgearth
I am trying to implement the shadow of an object flying above the earth( rendered from osgEarth). It is not working . I tried every technique, none of them are working. But if I render simple sphere of same size in place of osgearth, then shadow works on the sphere. Is there anything else I am missing?

Re: [osg-users] osgShadow and osgearth
Hi, as far as I know, osgEarth ist shader based, so you have to integrate your shadow in the osgEarth shaders (look for shader Composition) Cheers, Torben -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39269#39269 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Sumit, Please see my response to your post in the osgEarth forum for an answer. http://forum.osgearth.org/Shadow-in-osgearth-td6351086.html Glenn Waldron / Pelican Mapping / @glennwaldron On Wed, May 11, 2011 at 5:15 AM, Kumar Saurabh Arora saur...@vizexperts.com wrote: I am trying to implement the shadow of an object flying above the earth( rendered from osgEarth).

[osg-users] osgShadow and osgearth
Hi all, I m trying to get the shadows on earth(rendered by osgEarth). I have just inserted the earth node in osgShadow example. I could not get any shadow of mountains on terrain(self shadowing) by any shadowmap technique. I have tried to increase texture resolution but it's still not working. It was working for small terrain(created in osgShadow example model 2). Am I missing something?

Re: [osg-users] osgShadow and osgearth
Hi Sumit, Have you tried LispSM ? I have not tested it with osgEarth but it works with osgDEM data. See osgShadow -4 --lispsm example. With large Dataset you will probably have to take advantage of two Lispsm methods inherited from MinimalShadowMap void setModellingSpaceToWorldTransform( const osg::Matrix modellingSpaceToWorld ); and void setMaxFarPlane( float maxShadowDistance ); to optimize shadow map resolution usage. Look how they are used in osgShadow example.
