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

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::Binding Enumeration 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.
Constructor & Destructor Documentation
SoNormalBinding::SoNormalBinding (void) Constructor.
SoNormalBinding::~SoNormalBinding () [protected, virtual] Destructor.
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.
void SoNormalBinding::doAction (SoAction * action) [virtual] This function
performs the typical operation of a node for any action.
Reimplemented from SoNode.
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.
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.
void SoNormalBinding::pick (SoPickAction * action) [virtual] Action method
for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
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.
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.
Member Data Documentation
SoSFEnum SoNormalBinding::value The normal binding to use for subsequent
shape nodes in the scene graph.
