Hello, I have 2 questions about the lightSource node.
(1) Does lightSource affect all the geode nodes in the scenedata or only the ones that are under it in the sceneData structure? (2) In my application, a lightSource is attached to the main sceneNode, and this lightSource has a osg::group node (NodeA)as its child which contains several 3D models . There is also a pre render camera attached to the lightSource, and that pre render camera also has NodeA as child. When I set lightSource->setReferenceFrame(osg::LightSource::ABSOLUTE_RF), the color of the texture from the prerender camera varies as I use mouse to change the orientation of master camera displaying the 3D view. I don't know what is happening here. In my opinion, as the position and orientation of the pre render camera relative to the static 3D objects stay the same, the texture color should be the same too.
When Relative_RF is assigned, then the texture keeps the same however I change the master camera.
Can anyone give me some hints on that? Thanks a lot in advance! Best regards Shuiying _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
