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.

FIELDS

METHODS

79                         SoNormal()

81
82     static SoType       getClassTypeId()
83          Returns type identifier for this class.
