DESCRIPTION

61       This node defines a set of 3D surface normal vectors to be used by ver‐
62       tex-based shape nodes that follow it in the scene graph. This node does
63       not  produce  a visible result during rendering; it simply replaces the
64       current normals in the rendering state for  subsequent  nodes  to  use.
65       This  node  contains one multiple-valued field that contains the normal
66       vectors.
67
68       Surface normals are needed to compute lighting when the Phong  lighting
69       model  is  used.  Most vertex-based shapes that use normals can compute
70       default normals if none are specified, depending on the current  normal
71       binding.
