Detailed Description

The SoTransformSeparator class is a group node preserving the current transformations.

This node works like the SoSeparator group node, except that it only stores and restores the current model matrix transformation. Other appearance settings, like materials, textures, cameras, lights, etc, will affect the remaining parts of the scene graph after traversal, just like as for the SoGroup node.

Constructor & Destructor Documentation

SoTransformSeparator() [1/2]

SoTransformSeparator::SoTransformSeparator

(

void

)

Default constructor.

SoTransformSeparator() [2/2]

SoTransformSeparator::SoTransformSeparator

(

int

nChildren

)

Constructor.

The argument should be the approximate number of children which is expected to be inserted below this node. The number need not be exact, as it is only used as a hint for better memory resource allocation.

~SoTransformSeparator()

SoTransformSeparator::~SoTransformSeparator ( )

protectedvirtual

Destructor.

Member Function Documentation

audioRender()

void SoTransformSeparator::audioRender ( SoAudioRenderAction * action )

virtual

Action method for SoAudioRenderAction.

Does common processing for SoAudioRenderAction action instances.

Reimplemented from SoGroup.

callback()

void SoTransformSeparator::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 SoGroup.

doAction()

void SoTransformSeparator::doAction ( SoAction * action )

virtual

This function performs the typical operation of a node for any action.

Reimplemented from SoGroup.

getBoundingBox()

void SoTransformSeparator::getBoundingBox ( SoGetBoundingBoxAction * action )

virtual

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from SoGroup.

getClassTypeId()

SoType SoTransformSeparator::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

getFieldData()

const SoFieldData * SoTransformSeparator::getFieldData ( void ) const

protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoGroup.

getFieldDataPtr()

const SoFieldData ** SoTransformSeparator::getFieldDataPtr ( void )

staticprotected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Returns the SoFieldData class which holds information about fields in this node.

getMatrix()

void SoTransformSeparator::getMatrix ( SoGetMatrixAction * action )

virtual

Action method for SoGetMatrixAction.

Updates action by accumulating with the transformation matrix of this node (if any).

Reimplemented from SoGroup.

getPrimitiveCount()

void SoTransformSeparator::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 calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from SoGroup.

getTypeId()

SoType SoTransformSeparator::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Reimplemented from SoGroup.

GLRender()

void SoTransformSeparator::GLRender ( SoGLRenderAction * action )

virtual

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from SoGroup.

pick()

void SoTransformSeparator::pick ( SoPickAction * action )

virtual

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoGroup.
