SoClipPlaneElement::~SoClipPlaneElement () [protected], [virtual]¶

The destructor.

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.

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.

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.

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.

const SoClipPlaneElement * SoClipPlaneElement::getInstance (SoState *const state) [static]¶

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

int SoClipPlaneElement::getNum (void) const¶

Returns the current number of active clipping planes.

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

Returns the \index'th plane.

void SoClipPlaneElement::addToElt (const SbPlane & plane, const SbMatrix & modelMatrix) [protected], [virtual]¶

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

Reimplemented in SoGLClipPlaneElement.

SoClipPlaneElement::planes [protected]¶

List of currently active planes.

SoClipPlaneElement::startIndex [protected]¶

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