+// fVert2[] == array for 2nd point (3 elements are x, y, and z).
+// fVert3[] == array for 3rd point (3 elements are x, y, and z).
+//
+// Returns:
+// fNormalX == X vector for the normal vector
+// fNormalY == Y vector for the normal vector
+// fNormalZ == Z vector for the normal vector
+//*************************************************************************
