Any good OpenGL book will tell you about Normals or tutorials such as http://nehe.gamedev.net/
Also simple search of the examples files using something like 'normal' or 'setNormalArray' will show you many examples of setting normals such as in OpenSceneGraph\examples\osggeometry Gordon Tomlinson Product Manager 3d Technology & Project Wyvern Overwatch(r) An Operating Unit of Textron Systems -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Suvajit Sengupta Sent: Tuesday, April 20, 2010 3:55 AM To: [email protected] Subject: Re: [osg-users] [3rdparty] 3DShapefile immune to Lighting/Material Hi Gordon, Yes, now I am able to view the surfaces with shades after adding a normal to the geometries. But it was it of trial and error to set up the normal. I am still not clear theoretically what is a Normal and how a Normal Array for a given geometry is defined. I am trying something to read about it. It will good to have some references/links about a normal. ... Thank you!
