a vertex is a point of intersection between 2 or more paths. a control vertex is an intersection of two control paths that calculates the shape of a B Spline. this is the true definition in regards to Nurbs identification regardless of what some documentation may say. CV's are vertexes/verticies. Feel free to prove me wrong if you think you can. MWaaaaa hahaha hahahaha ahahahahaha LOL
