Detailed Description

The SoPointSizeElement changes the point size setting of the render state.

Requests from the scene graph to change the point size when rendering point primitives will be made through this element.

The SoPointSizeElement class itself is just a generic abstraction for the underlying So*PointSizeElement classes with code specific for each supported immediate mode rendering library.

Constructor & Destructor Documentation

~SoPointSizeElement()

SoPointSizeElement::~SoPointSizeElement ( void )

protectedvirtual

Destructor.

Member Function Documentation

createInstance()

void * SoPointSizeElement::createInstance ( void )

static

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

Creates a new instance of the class type corresponding to the SoType object.

get()

float SoPointSizeElement::get ( SoState *const state )

static

Static method for returning the current point size setting in the given traversal state.

getClassStackIndex()

int SoPointSizeElement::getClassStackIndex ( void )

static

This static method returns the state stack index for the class.

getClassTypeId()

SoType SoPointSizeElement::getClassTypeId ( void )

static

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

getDefault()

float SoPointSizeElement::getDefault ( void )

static

Returns default point size setting.

init()

void SoPointSizeElement::init ( SoState * state )

virtual

Initializes the element to its default value. The default value for point size is 0.0.

Reimplemented from SoFloatElement.

Reimplemented in SoGLPointSizeElement.

initClass()

void SoPointSizeElement::initClass ( void )

static

Initialize relevant common data for all instances, like the type system.

set() [1/2]

void SoPointSizeElement::set ( SoState *const state, const float pointSize )

static

Static method for setting the current pointSize value in the given traversal state.

set() [2/2]

void SoPointSizeElement::set ( SoState *const state, SoNode *const node, const float pointSize )

static

Static method for setting the current pointSize value in the given traversal state.
