if you look at the implementation of osgShadow, in particular the osg::ShadowMap class you will see how to render the scene from the light's point of view for the purpose of creating a depth map. The depth map is then later used when rendering the main view, for superimposing a shadow.
Warning: the default behavior turns on backface culling and only enables the back faces for rendering. This may not be what you want - but it's easy enough to change. 2012/12/12 Peterakos <[email protected]> > Hello. > > Lets say there is cessna as a child in LightSource group. > LightSource has 1 light. > > What i want to do is to get the depth map from light's point of view. > How can i do this ? > > I am thinking of placing a Camera as a child in LightSource. > This camera will look at exactly the same direction as the light and > will also has the same position. > Is this the right way to do it ? > > ( I know how to make camera render to texture) > > Thank you for your time. > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >
