Public Member Functions

 SoNormalBinding ()
 Creates a normal binding node with default settings.
virtual void doAction (SoAction *action)
 This method performs the "typical" operation of a node for any action.
virtual void GLRender (SoGLRenderAction *action)
 These virtual functions implement all of the actions for nodes, Most of the default implementations do nothing.
virtual void callback (SoCallbackAction *action)
virtual void pick (SoPickAction *action)

Static Public Member Functions

static void initClass ()
 Initializes base node class.

Public Attributes

Fields
SoSFEnum value
 Specifies how to bind normals to shapes.

Protected Member Functions

virtual ~SoNormalBinding ()
virtual SbBool readInstance (SoInput *in, unsigned short flags)
 Reads stuff into instance. Upgrades old bindings.

Detailed Description

This node specifies how the current normals are bound to shapes that follow in the scene graph. Each shape node may interpret bindings differently.

The bindings for faces and vertices are meaningful only for shapes that are made from faces and vertices. Similarly, the indexed bindings are only used by the shapes that allow indexing. For bindings that require multiple normals, be sure to have at least as many normals defined as are necessary; otherwise, errors will occur.

File Format/Default
NormalBinding {
  value PER_VERTEX_INDEXED
}
Action Behavior
SoGLRenderAction, SoCallbackAction, SoRayPickAction
