[osg-users] How to make sure that both the back and the front side of a polygon are lit...
Hello everybody, I would like to have both the front and the back side of the polygons I draw lit. Right now I have specified the normals and only the side which is on the same side as that of the normals is being lit.. Should I render the same-geometry twice and add normals to it so that it is lit on both sides.. I realized this might not be the right way to do it.. Does any of you have any suggestion?

Re: [osg-users] unable to link ..
The list of libraries that it is linking against .. * * *libosg.a libosgDB.a libosgGA.a libosgManipulator.a libosgShadow.a libosgTerrain.a libosgUtil.alibosgVolume.a* *libosgAnimation.a libosgFX.a libosgIntrospection.a libosgParticle.a libosgSim.a libosgText.a libosgViewer.a libosgWidget.a* * * I included everything .. since I was getting a lot of linker errors .. I am not sure if even that could cause problems.. Sunil.

[osg-users] CompositeViewerFLTK CompositeViewerQT CompositeViewerQOSG are not documented .. are these not supposed to be used??
Hello everybody, CompositeViewerFLTK CompositeViewerQT CompositeViewerQOSG are left undocumented .. is there a reason behind it? does it mean it is not supposed to be used?

Re: [osg-users] AutoTransform
Thanks John, I had run the example before .. but after you told me the difference .. I could figure out the difference in the output... Sunil.

[osg-users] AutoTransform
Hello Everybody, I would like to know as to what is the difference between *ROTATE_TO_SCREEN* *ROTATE_TO_CAMERA* in the AutoTransform class. I was also wondering if there is some inbuilt feature to place an axis in the corner of the screen indicating the world axis .. as is common in most cad applications.. Thanks in advance...
