Detailed Description

The SoVRMLVertexPoint class is a superclass for point based VRML shapes.

Constructor & Destructor Documentation

SoVRMLVertexPoint()

SoVRMLVertexPoint::SoVRMLVertexPoint ( void )

~SoVRMLVertexPoint()

SoVRMLVertexPoint::~SoVRMLVertexPoint ( )

protectedvirtual

Destructor.

Member Function Documentation

callback()

void SoVRMLVertexPoint::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 SoShape.

computeBBox()

void SoVRMLVertexPoint::computeBBox ( SoAction * action, SbBox3f & box, SbVec3f & center )

protectedvirtual

Implemented by SoShape subclasses to let the SoShape superclass know the exact size and weighted center point of the shape's bounding box.

The bounding box and center point should be calculated and returned in the local coordinate system.

The method implements action behavior for shape nodes for SoGetBoundingBoxAction. It is invoked from SoShape::getBoundingBox(). (Subclasses should not override SoNode::getBoundingBox().)

The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry.

Implements SoShape.

doAction()

void SoVRMLVertexPoint::doAction ( SoAction * action )

virtual

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

Reimplemented from SoNode.

getBoundingBox()

void SoVRMLVertexPoint::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 SoShape.

Reimplemented in SoVRMLPointSet.

getClassTypeId()

SoType SoVRMLVertexPoint::getClassTypeId ( void )

static

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

getFieldData()

const SoFieldData * SoVRMLVertexPoint::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 SoVRMLGeometry.

Reimplemented in SoVRMLPointSet.

getFieldDataPtr()

const SoFieldData ** SoVRMLVertexPoint::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.

getPrimitiveCount()

void SoVRMLVertexPoint::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 SoShape.

getTypeId()

SoType SoVRMLVertexPoint::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 SoVRMLGeometry.

Reimplemented in SoVRMLPointSet.

GLRender()

void SoVRMLVertexPoint::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 SoShape.

Reimplemented in SoVRMLPointSet.

initClass()

void SoVRMLVertexPoint::initClass ( void )

static

notify()

void SoVRMLVertexPoint::notify ( SoNotList * l )

virtual

Notifies all auditors for this instance when changes are made.

Reimplemented from SoVRMLGeometry.

pick()

void SoVRMLVertexPoint::pick ( SoPickAction * action )

virtual

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

shouldGLRender()

SbBool SoVRMLVertexPoint::shouldGLRender ( SoGLRenderAction * action )

protectedvirtual

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

Reimplemented from SoVRMLGeometry.
