Detailed Description

The SoGLDepthBufferElement controls the OpenGL depth buffer.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since

Coin 3.0

Constructor & Destructor Documentation

~SoGLDepthBufferElement()

SoGLDepthBufferElement::~SoGLDepthBufferElement ( void )

protectedvirtual

Destructor.

Member Function Documentation

createInstance()

void * SoGLDepthBufferElement::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.

getClassStackIndex()

int SoGLDepthBufferElement::getClassStackIndex ( void )

static

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

getClassTypeId()

SoType SoGLDepthBufferElement::getClassTypeId ( void )

static

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

init()

void SoGLDepthBufferElement::init ( SoState * state )

virtual

Internal Coin method.

Reimplemented from SoDepthBufferElement.

initClass()

void SoGLDepthBufferElement::initClass ( void )

static

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

pop()

void SoGLDepthBufferElement::pop ( SoState * state, const SoElement * prevTopElement )

virtual

Internal Coin method.

Reimplemented from SoDepthBufferElement.

push()

void SoGLDepthBufferElement::push ( SoState * state )

virtual

Internal Coin method.

Reimplemented from SoDepthBufferElement.

setElt()

void SoGLDepthBufferElement::setElt ( SbBool test, SbBool write, DepthWriteFunction function, SbVec2f range )

protectedvirtual

Set this element's values.

Reimplemented from SoDepthBufferElement.
