In directory sc8-pr-cvs1:/tmp/cvs-serv8787

Added Files:
	ssgVertSplitter.cxx 
Log Message:
Andy Ross's vertex splitter

--- NEW FILE: ssgVertSplitter.cxx ---
////////////////////////////////////////////////////////////////////////
//
// Copyright 2003, Andrew Ross
//
// Walk through an indexed triangle list, splitting vertices that
// share "sharp" edges, and calculate normals for the resulting mesh.
//
// This code should really live inside the OptVertexList class in
// ssgOptimizer.cxx, whose data model is almost 1:1 compatible with
// the indexed triangle representation here.  It is a separate file
// because it comes from separate code that Andy Ross wrote for a
// different project, and this was the cleanest way to do the port.
