Hi, The original code is :
Code: vPosition = ViewMatrix * ModelMatrix * vec4(Vertex * ModelScale, 1.0); So I think you can use this : Code: vPosition = osg_ModelViewMatrix * vec4(Vertex * ModelScale, 1.0); because "osg_ModelViewMatrix" is equivalent to "ViewMatrix * ModelMatrix". > Where i can find all the osg built-in variables? In "State.cpp" : look for "osg_*", you'll find : - osg_ModelViewMatrix => equivalent to gl_ModelViewMatrix - osg_ModelViewProjectionMatrix => equivalent to gl_ModelViewProjectionMatrix - osg_ProjectionMatrix => equivalent to gl_ProjectionMatrix - osg_NormalMatrix => equivalent to gl_NormalMatrix In "SceneView.cpp" : look for "osg_*", you'll find : - osg_ViewMatrix - osg_ViewMatrixInverse Cheers, Aurelien ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=52867#52867 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
