Detailed Description

The SoClipPlaneElement class is used to manage the clip plane stack.

Constructor & Destructor Documentation

◆ ~SoClipPlaneElement()

SoClipPlaneElement::~SoClipPlaneElement ( )
protectedvirtual

The destructor.

Member Function Documentation

◆ createInstance()

void * SoClipPlaneElement::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.

◆ init()

void SoClipPlaneElement::init ( SoState state)
virtual

This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLClipPlaneElement.

◆ push()

void SoClipPlaneElement::push ( SoState state)
virtual

This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.

Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().

Reimplemented from SoAccumulatedElement.

◆ add()

void SoClipPlaneElement::add ( SoState *const  state,
SoNode *const  node,
const SbPlane plane 
)
static

Adds plane as an active plane. Calls addToElt() to do the job.

◆ getInstance()

const SoClipPlaneElement * SoClipPlaneElement::getInstance ( SoState *const  state)
static

Returns the current (top-of-stack) element.

◆ getNum()

int SoClipPlaneElement::getNum ( void  ) const

Returns the current number of active clipping planes.

◆ get()

const SbPlane & SoClipPlaneElement::get ( const int  index,
const SbBool  inworldspace = TRUE 
) const

Returns the index'th plane.

◆ addToElt()

void SoClipPlaneElement::addToElt ( const SbPlane plane,
const SbMatrix modelMatrix 
)
protectedvirtual

This method adds the clipping plane, plane, to an instance. modelmatrix is the current model matrix.

Reimplemented in SoGLClipPlaneElement.

Member Data Documentation

◆ planes

SoClipPlaneElement::planes
protected

List of currently active planes.

◆ startIndex

SoClipPlaneElement::startIndex
protected

Index of first clip plane in this element. Used to disable clip planes in SoGLClipPlaneElement::pop().
