NAME
SoNormalBinding -The SoNormalBinding class is a node for specifying normal vector bindings.
Use nodes of this type to specify how to map normal vectors from SoNormal nodes in the scene graph to shape nodes.
SYNOPSIS
#include <Inventor/nodes/SoNormalBinding.h>
Inherits SoNode.
Public Types
enum Binding { OVERALL = SoNormalBindingElement::OVERALL, PER_PART = SoNormalBindingElement::PER_PART, PER_PART_INDEXED = SoNormalBindingElement::PER_PART_INDEXED, PER_FACE = SoNormalBindingElement::PER_FACE, PER_FACE_INDEXED = SoNormalBindingElement::PER_FACE_INDEXED, PER_VERTEX = SoNormalBindingElement::PER_VERTEX, PER_VERTEX_INDEXED = SoNormalBindingElement::PER_VERTEX_INDEXED, DEFAULT = PER_VERTEX_INDEXED, NONE = PER_VERTEX_INDEXED }

Detailed Description
The SoNormalBinding class is a node for specifying normal vector bindings.
Use nodes of this type to specify how to map normal vectors from SoNormal nodes in the scene graph to shape nodes.
FILE FORMAT/DEFAULTS:
NormalBinding { value PER_VERTEX_INDEXED }
Member Enumeration Documentation
enum SoNormalBinding::BindingEnumeration of available types of mappings. See documentation of SoMaterialBinding node for explanation of the different values.
Note that SoNormalBinding::DEFAULT and SoNormalBinding::NONE has been obsoleted and are both mapped to SoNormalBinding::PER_VERTEX_INDEXED.

Member Function Documentation
void SoNormalBinding::initClass (void) [static]Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoNode.
References SoNode::VRML1.
void SoNormalBinding::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
References SoOverrideElement::getNormalBindingOverride(), SoAction::getState(), SoField::isIgnored(), SoNode::isOverride(), SoFieldContainer::set(), SoOverrideElement::setNormalBindingOverride(), and value.
Referenced by callback(), getPrimitiveCount(), GLRender(), and pick().
void SoNormalBinding::GLRender (SoGLRenderAction * action) [virtual]Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoNode.
References doAction().
void SoNormalBinding::callback (SoCallbackAction * action) [virtual]Action method for SoCallbackAction.
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.
Reimplemented from SoNode.
References doAction().
void SoNormalBinding::pick (SoPickAction * action) [virtual]Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
References doAction().
void SoNormalBinding::getPrimitiveCount (SoGetPrimitiveCountAction * action) [virtual]Action method for the SoGetPrimitiveCountAction.
Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.
Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.
Reimplemented from SoNode.
References doAction().
SbBool SoNormalBinding::readInstance (SoInput * in, unsigned short flags) [protected, virtual]This method is mainly intended for internal use during file import operations.
It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type.
TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE.
flags is used internally during binary import when reading user extension nodes, group nodes or engines.
Reimplemented from SoNode.
References SoNode::readInstance(), and value.
Member Data Documentation
SoSFEnum SoNormalBinding::valueThe normal binding to use for subsequent shape nodes in the scene graph.
Referenced by doAction(), readInstance(), and SoNormalBinding().
