Detailed Description

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


Constructor & Destructor Documentation

SoVRMLVertexPoint::SoVRMLVertexPoint ( void  )
protected

Constructor.

References color, and coord.

SoVRMLVertexPoint::~SoVRMLVertexPoint ( )
protectedvirtual

Destructor.


Member Function Documentation

SoType SoVRMLVertexPoint::getClassTypeId ( void  )
static

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

Reimplemented from SoVRMLGeometry.

Reimplemented in SoVRMLPointSet.

SoType SoVRMLVertexPoint::getTypeId ( void  ) const
virtual

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

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
SoGroup * group = (SoGroup *)node; // safe downward cast, knows the type
}
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all 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 Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoVRMLGeometry.

Reimplemented in SoVRMLPointSet.

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.

Reimplemented from SoVRMLGeometry.

Reimplemented in SoVRMLPointSet.

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.

void SoVRMLVertexPoint::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 SoVRMLGeometry.

Reimplemented in SoVRMLPointSet.

void SoVRMLVertexPoint::doAction ( SoAction action)
virtual

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

Reimplemented from SoNode.

References color, coord, and SoNode::doAction().

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 who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoShape.

Reimplemented in SoVRMLPointSet.

References color, coord, and SoNode::GLRender().

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 calculates their bounding box also overrides this method to change the relevant state variables.

Reimplemented from SoShape.

Reimplemented in SoVRMLPointSet.

References SoShape::getBoundingBox().

Referenced by SoVRMLPointSet::getBoundingBox().

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.

References SoShape::callback().

void SoVRMLVertexPoint::pick ( SoPickAction action)
virtual

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

References SoNode::pick().

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 calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoShape.

References SoGetPrimitiveCountAction::addNumPoints(), coord, SoMField::getNum(), SoVRMLCoordinate::point, and SoShape::shouldPrimitiveCount().

void SoVRMLVertexPoint::notify ( SoNotList l)
virtual

Notifies all auditors for this instance when changes are made.

Reimplemented from SoVRMLGeometry.

References SoVRMLGeometry::notify().

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.

References coord, and SoVRMLGeometry::shouldGLRender().

Referenced by SoVRMLPointSet::GLRender().

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.
