See documentation of \fBSoMaterialBinding\fP node for explanation of the different values\&. .PP Note that SoNormalBinding::DEFAULT and SoNormalBinding::NONE has been obsoleted and are both mapped to SoNormalBinding::PER_VERTEX_INDEXED\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoNormalBinding::SoNormalBinding (void)" Constructor\&. .SS "SoNormalBinding::~SoNormalBinding ()\fC [protected]\fP, \fC [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoNormalBinding::getTypeId (void) const\fC [virtual]\fP" .PP Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example: .PP .PP .nf void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } } .fi .PP .PP For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP subclasses\&. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&. .PP For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups\&. .PP Implements \fBSoBase\fP\&. .SS "const \fBSoFieldData\fP * SoNormalBinding::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP" Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. .PP Reimplemented from \fBSoFieldContainer\fP\&. .SS "void SoNormalBinding::doAction (\fBSoAction\fP *action)\fC [virtual]\fP" This function performs the typical operation of a node for any action\&. .PP Reimplemented from \fBSoNode\fP\&. .SS "void SoNormalBinding::GLRender (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP" Action method for the \fBSoGLRenderAction\fP\&. .PP 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\&. .PP Reimplemented from \fBSoNode\fP\&. .SS "void SoNormalBinding::callback (\fBSoCallbackAction\fP *action)\fC [virtual]\fP" Action method for \fBSoCallbackAction\fP\&. .PP Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&. .PP Reimplemented from \fBSoNode\fP\&. .SS "void SoNormalBinding::pick (\fBSoPickAction\fP *action)\fC [virtual]\fP" Action method for \fBSoPickAction\fP\&. .PP Does common processing for \fBSoPickAction\fP \fIaction\fP instances\&. .PP Reimplemented from \fBSoNode\fP\&. .SS "void SoNormalBinding::getPrimitiveCount (\fBSoGetPrimitiveCountAction\fP *action)\fC [virtual]\fP" Action method for the \fBSoGetPrimitiveCountAction\fP\&. .PP Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the \fIaction\fP\&. .PP Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables\&. .PP Reimplemented from \fBSoNode\fP\&. .SS "SbBool SoNormalBinding::readInstance (\fBSoInput\fP *in, unsigned shortflags)\fC [protected]\fP, \fC [virtual]\fP" This method is mainly intended for internal use during file import operations\&. .PP It reads a definition of an instance from the input stream \fIin\fP\&. The input stream state points to the start of a serialized / persistant representation of an instance of this class type\&. .PP \fCTRUE\fP or \fCFALSE\fP 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 \fCFALSE\fP\&. .PP \fIflags\fP is used internally during binary import when reading user extension nodes, group nodes or engines\&. .PP Reimplemented from \fBSoNode\fP\&. .SH "Member Data Documentation" .PP .SS "\fBSoSFEnum\fP SoNormalBinding::value" The normal binding to use for subsequent shape nodes in the scene graph\&. .SH "Author" .PP Generated automatically by Doxygen for Coin from the source code\&.
