I am just curious how OpenGL handles normals. I would like to know if you can only specify a normal for an entire polygon, or you can specify a normal for each vertex of the polygon.

Yes, you can specify a normal for an entire polygon or by vertex in OpenGL.

See http://ask.ii.uib.no/ebt-bin/nph-dweb/dynaweb/SGI_Developer/OpenGL_PG/ for more info on any OpenGL stuff.
