[osg-users] Getting texture coordinates and normals of each vertex of a loaded model

[Franclin Foping]

Dear All,
 Is there any algorithm in OSG to compute normals and texture coordinates of each vertex of a loaded model? 
 With the osg::TriangleFunctor and osg::TriangleIndexFunctor, I can perfectly find out all triangles making up of a given node. However, the (big) issue is to be able to find out normals and texture coordinates of each vertex of a loaded model. 
 Any help will be appreciated.
 Waiting for your reply.
 Franclin.
